Subject: [PATCH 1/6] feat: MCP server, safety gate, and LLM provider
 abstraction

Freeze the 11-tool MCP interface in docs/MCP-INTERFACE.md and back it with a
FastMCP server. Extract pipeline functions from scenarios/run_kill_chain.py
into phantom_secops/core.py so the Python orchestrator and MCP server share
one implementation.

- phantom_secops/mcp/safety.py centralises the lab-target whitelist and the
  no-runnable-POC prose validator. Tool wrappers and the MCP boundary both
  defer to it (defense-in-depth).
- phantom_secops/llm/ adds a Provider protocol with three implementations
  (none, anthropic, phantom_mesh). LLM-augmented prose is validated against
  safety.is_safe_prose before being merged into output; failures fall back
  to deterministic templates so the pipeline never blocks on a flaky LLM.
- Test suite grows 7 -> 32: MCP protocol smoke tests, safety unit tests,
  no-runnable-POC invariant, malicious-provider invariant under the LLM
  path, lifecycle confirmation invariant.
- Makefile gains mcp-serve / mcp-dev. requirements-dev.txt adds mcp[cli].
  scripts/lint.py covers the new phantom_secops/ package tree.

+# MCP Interface — phantom-secops
+
+> Frozen contract. The MCP server, phantom-mesh adapter, Claude Code subagent, and the Python reference orchestrator all depend on the names, schemas, and safety gates documented here. Changes to anything below are breaking and require updating all four call sites in lockstep.
+>
+> Surface: **11 tools, 2 resource schemes**.
+
+## Server identity
+
+| Field | Value |
+|---|---|
+| MCP server name | `phantom-secops` |
+| Tools / Resources | 11 / 2 |
+| Transport | `stdio` (primary) and `http` (optional, for remote agents) |
+| Protocol version | MCP 2025-06-18 |
+| Required runtime | Python ≥3.11, Docker (only for `active_in_lab` and `lifecycle` tools) |
+
+## Naming convention
+
+`{verb}_{object}[_{qualifier}]`, snake_case, all lowercase. The qualifier is mandatory when the verb has multiple safety profiles (e.g. `lab_up_confirm`).
+
+The 11 tools below are grouped by **safety class**, not by red/blue. Mixing red/blue in the same server is intentional — agents shouldn't have to know which "side" a tool belongs to; they just call it.
+
+---
+
+## Safety classes
+
+| Class | Means | Tools require user/agent confirmation? |
+|---|---|---|
+| `read_only` | No network egress, no filesystem writes outside `reports/runs/<ts>/` | No |
+| `active_in_lab` | Probes a target inside the `secops-lab` docker network | No (gated by lab-network check) |
+| `lifecycle` | Brings up/tears down the docker lab | **Yes** — must pass `confirm: true` |
+
+Every `active_in_lab` tool **must** call `safety.assert_lab_target(target)` before doing anything. The check is centralised in `mcp/safety.py` and validates against the hard-coded list `{juice-shop, dvwa, dvwa-db, metasploitable, attacker}`. Any other value returns an `ErrorOutput` with `code="not_a_lab_target"`.
+
+---
+
+## Tool catalogue
+
+### 1. `recon_host` — `active_in_lab`
+
+Scans an in-lab host with nmap (top 1000 ports + service version). Wraps `tools/nmap_runner.py`.
+
+```ts
+input: {
+  target: "juice-shop" | "dvwa" | "dvwa-db" | "metasploitable" | "attacker",
+  ports?: "top-1000" | string,   // default "top-1000"; explicit list e.g. "80,443,3306"
+  scan_type?: string,             // default "-sV"
+}
+
+output: {
+  target: string,
+  open_ports: Array<{
+    port: number,
+    protocol: string,        // "tcp" | "udp"
+    service: string,         // "http", "mysql", ...
+    version: string | null,  // "Apache 2.4.41" or null
+  }>,
+  scan_type: "nmap",
+}
+
+// or, on error:
+output: { error: string, target?: string, lab_services?: string[] }
+```
+
+**Side effects**: shells `docker exec` into `secops-attacker`. No filesystem writes.
+**Latency budget**: 120 s timeout enforced inside the wrapper.
+
+---
+
+### 2. `vuln_scan_web` — `active_in_lab`
+
+Runs nuclei against an in-lab HTTP target. Wraps `tools/nuclei_runner.py`.
+
+```ts
+input: {
+  target_url: string,         // must contain a lab service hostname
+  severity?: string,          // CSV; default "low,medium,high,critical"
+  timeout_s?: number,         // default 90
+}
+
+output: {
+  target: string,
+  findings: Array<{
+    id: string | null,         // nuclei template-id
+    cve: string | null,
+    severity: "info" | "low" | "medium" | "high" | "critical" | null,
+    title: string | null,
+    evidence: string | null,   // matched-at URL
+    tool: "nuclei",
+    raw: string,               // truncated raw JSON, ≤400 chars
+  }>,
+}
+```
+
+**Side effects**: shells `docker exec` into `secops-attacker`; on first run installs nuclei via `go install`.
+**Latency budget**: `timeout_s + 30` s.
+
+---
+
+### 3. `scan_logs_for_anomalies` — `read_only`
+
+Pattern-matches access logs to produce raw alerts. Logic from `_blue_log_anomaly` in `run_kill_chain.py:174`.
+
+```ts
+input: {
+  source?: "lab_logs" | "mock",   // default "lab_logs"; "mock" reads lab/mocks/attack-log.txt
+  log_path?: string,              // override; absolute path inside repo
+}
+
+output: {
+  alerts: Array<{
+    ts: string,                   // ISO8601 UTC
+    source_ip: string,            // IPv4 or "unknown"
+    asset: string,                // "juice-shop" | "dvwa" | ...
+    category: "traversal" | "sqli" | "xss" | "admin_path" | "scanner",
+    evidence: string,             // raw log line, ≤200 chars
+    severity_hint: "low" | "medium" | "high",
+  }>,
+  source: string,                  // resolved log file path
+}
+```
+
+**Side effects**: none. URL-decodes each line before pattern-matching (the existing implementation does this).
+
+---
+
+### 4. `triage_alerts` — `read_only`
+
+Groups raw alerts by `(source_ip, category)` and assigns priority. Logic from `_blue_alert_triage`.
+
+```ts
+input: {
+  alerts: Array<Alert>,           // shape from scan_logs_for_anomalies.alerts[]
+}
+
+output: {
+  triaged: Array<{
+    ts: string,
+    priority: "P1" | "P2" | "P3",
+    asset: string,
+    summary: string,              // "<category> pattern from <ip>"
+    count: number,
+    evidence: string[],           // up to 3 sample lines
+  }>,
+}
+```
+
+**Promotion rules** (frozen):
+- `severity_hint=high` → P2 by default; P1 once `count ≥ 2`
+- `severity_hint=medium` → promote P3 → P2
+- `severity_hint=low` → stays P3
+
+---
+
+### 5. `correlate_threats` — `read_only`
+
+Joins triaged alerts into per-actor narratives with ATT&CK phase tags. Logic from `_blue_threat_correlate`.
+
+```ts
+input: {
+  triaged: Array<TriagedGroup>,   // shape from triage_alerts.triaged[]
+}
+
+output: {
+  actors: Array<{
+    actor: string,                  // source IP
+    first_seen: string,             // ISO8601
+    last_seen: string,
+    phases_observed: string[],      // e.g. ["TA0001", "TA0043"]
+    alert_summaries: string[],
+    narrative: string,              // human-readable English summary
+    confidence: "low" | "medium" | "high",
+  }>,
+}
+```
+
+**Phase mapping** (frozen):
+- `scanner` → `TA0043` (Reconnaissance)
+- `sqli`, `xss`, `traversal` → `TA0001` (Initial Access)
+- `admin_path` → `TA0007` (Discovery)
+
+---
+
+### 6. `suggest_exploit_prose` — `read_only`
+
+Generates **text-only** exploit explanations from vuln-scan findings. **Never returns runnable payloads.** This is the safety-critical tool — its name carries `_prose` to make the constraint visible to every caller.
+
+```ts
+input: {
+  findings: Array<Finding>,        // shape from vuln_scan_web.findings[]
+  use_llm?: boolean,                // default false; when true, calls LLMProvider for prose
+}
+
+output: {
+  markdown: string,                  // full markdown document, "# Exploit Suggestions\n..."
+  has_runnable_poc: false,           // INVARIANT: always false; checked by tests
+}
+```
+
+**Hard constraints** (enforced by `tests/test_no_runnable_poc.py`):
+- Output must not contain shell commands, curl invocations, payload strings, or template strings that would execute if pasted.
+- The string `has_runnable_poc: false` is a load-bearing assertion; do not change.
+
+---
+
+### 7. `compose_pentest_report` — `read_only`
+
+Renders the red-team-side markdown report.
+
+```ts
+input: {
+  recon: ReconOutput,              // from recon_host
+  vuln: VulnScanOutput,            // from vuln_scan_web
+  exploit_suggestions_md: string,  // from suggest_exploit_prose.markdown
+  timeline: Array<[string, string]>, // [[t_seconds, label], ...]
+}
+
+output: {
+  markdown: string,
+  byte_size: number,
+}
+```
+
+---
+
+### 8. `compose_incident_report` — `read_only`
+
+Renders the blue-team-side markdown report.
+
+```ts
+input: {
+  triaged: Array<TriagedGroup>,
+  actors: Array<Actor>,            // from correlate_threats
+  timeline: Array<[string, string]>,
+}
+
+output: {
+  markdown: string,
+  byte_size: number,
+  mttd_seconds: number,            // first red event → first triaged alert
+}
+```
+
+---
+
+### 9. `lab_status` — `read_only`
+
+Reports docker lab health. Wraps `docker compose ps` in JSON form.
+
+```ts
+input: {}   // no parameters
+
+output: {
+  network_present: boolean,        // is "secops-lab" network up?
+  services: Array<{
+    name: "juice-shop" | "dvwa" | "dvwa-db" | "attacker" | "log-collector",
+    state: "running" | "exited" | "absent",
+    health: "healthy" | "unhealthy" | "starting" | "none",
+  }>,
+}
+```
+
+**Side effects**: reads docker state; does not modify.
+
+---
+
+### 10. `lab_up` — `lifecycle`
+
+Brings up the isolated docker lab.
+
+```ts
+input:  { confirm: true }
+output: { ok: boolean, log: string }   // log = last 2 KB of docker compose output
+```
+
+Idempotent. Calling without `confirm: true` returns `{ error: "lifecycle_action_requires_confirmation" }` and does nothing.
+
+### 11. `lab_down` — `lifecycle`
+
+Tears down the docker lab. Removes containers and volumes; **never** touches the `reports/runs/` directory on the host.
+
+```ts
+input:  { confirm: true }
+output: { ok: boolean, log: string }
+```
+
+Same confirmation requirement as `lab_up`. Both lifecycle tools are intended for interactive callers (Claude Code, phantom-mesh dispatch with a human-authored prompt) — CI lanes should use `make lab-up` / `make lab-down` directly rather than going through MCP.
+
+---
+
+## Resources
+
+Resources are read-only artifacts the agent can fetch by URI without invoking a tool.
+
+### `phantom-secops://runs/{run_id}/{filename}`
+
+```
+run_id      = ISO timestamp dir name, e.g. "2026-05-05-1430"
+filename    ∈ { recon.json, vuln-scan.json, alerts.jsonl, triage-queue.jsonl,
+                kill-chains.jsonl, exploit-suggestions.md,
+                pentest-report.md, incident-report.md }
+```
+
+`run_id="latest"` resolves to the newest run dir at fetch time.
+
+### `phantom-secops://mocks/{name}`
+
+```
+name ∈ { recon-juice-shop.json, vuln-scan-juice-shop.json, attack-log.txt }
+```
+
+---
+
+## Error model
+
+Every tool returns either its success shape or a flat error envelope:
+
+```ts
+{
+  error: string,                   // short code, snake_case
+  message?: string,                // human-readable detail
+  context?: object,                // tool-specific extras
+}
+```
+
+Frozen error codes:
+
+| Code | Meaning |
+|---|---|
+| `not_a_lab_target` | Target is not in the lab service whitelist |
+| `lab_network_down` | `secops-lab` docker network is not up |
+| `tool_timeout` | Underlying CLI exceeded its budget |
+| `tool_nonzero_exit` | Underlying CLI returned non-zero |
+| `parse_failed` | Output could not be parsed (e.g. malformed nmap XML) |
+| `lifecycle_action_requires_confirmation` | Lifecycle tool called without `confirm: true` |
+| `bad_input` | Input failed schema validation |
+
+---
+
+## Versioning
+
+This document is version `1.0.0`. The MCP server reports the same version in its handshake. Adapters may pin to a major version.
+
+- **Patch** bumps: docs-only, schema-additive (new optional input fields, new optional output fields).
+- **Minor** bumps: new tools, new error codes, new resources.
+- **Major** bumps: any rename, removal, type change, or safety-class change.
+
+Major bumps require updating: `mcp/server.py`, `mcp/schemas.py`, `agents/red/*.toml`, `agents/blue/*.toml`, `.claude/agents/secops-runner.md`, `scenarios/run_kill_chain.py`, and this file — in the same PR.

Subject: [PATCH 2/6] feat: MCP adapters for Claude Code and phantom-mesh TOML
 configs

Wire the MCP server up to multiple agent runtimes so the same SecOps tools
drive workflows from any MCP client.

- .mcp.json + .claude/agents/secops-runner.md let Claude Code drive a full
  kill-chain via the MCP tools. The subagent enforces lab-target gating,
  prose-only exploit text, and lifecycle confirmation through the MCP
  layer's safety guarantees rather than prompt rules alone.
- agents/{red,blue}/*.toml updated to reference MCP tool IDs through a new
  [mcp] block (servers list + per-tool server field). Removed references to
  fictional tools (http_probe, dns_enum, cve_lookup, nikto_runner, stats)
  that no MCP tool backs. Format is provisional pending phantom-tools /
  phantom-runtime release (May-June 2026).
- docs/INTEGRATIONS.md catalogues every supported runtime (Python ref,
  Claude Code, phantom-mesh, Cursor, Continue, OpenAI Agents, LangGraph)
  with minimal config snippets and current status.

+name: secops-runner
+description: Drives a full red/blue kill-chain against the phantom-secops lab and produces side-by-side pentest + incident reports. Use when the user asks to run a kill-chain, scan a lab target, triage alerts, or produce a SecOps report. Pairs with the phantom-secops MCP server.
+tools: mcp__phantom-secops__recon_host, mcp__phantom-secops__vuln_scan_web, mcp__phantom-secops__scan_logs_for_anomalies, mcp__phantom-secops__triage_alerts, mcp__phantom-secops__correlate_threats, mcp__phantom-secops__suggest_exploit_prose, mcp__phantom-secops__compose_pentest_report, mcp__phantom-secops__compose_incident_report, mcp__phantom-secops__lab_status, Read, Write, Bash
+---
+
+You drive the phantom-secops kill-chain via MCP tools. The pipeline is fixed; your job is sequencing, persistence, and the final report comparison.
+
+## Hard rules
+
+1. **Lab targets only.** The MCP layer refuses external targets (`error: not_a_lab_target`). If a tool refuses, **stop** and report — do not retry with a different target.
+2. **No runnable exploits.** `suggest_exploit_prose` returns markdown with `has_runnable_poc: false`. Preserve that property in everything you write. Never invent payloads, shellcode, or curl commands.
+3. **Lifecycle requires confirm.** `lab_up` / `lab_down` need `confirm=true`. Only call them if the user has explicitly asked to bring the lab up/down — never preemptively.
+4. **Persist artifacts under `reports/runs/<ts>/`.** The user's run directory is the source of truth; do not write reports anywhere else.
+
+## Workflow
+
+Default target is `juice-shop` unless the user names another lab service.
+
+1. Check `lab_status`. If `network_present=false`, tell the user the lab needs to come up; do not auto-start it.
+2. Pick a run timestamp (`YYYY-MM-DD-HHMM` UTC) and create `reports/runs/<ts>/`.
+3. **Red:**
+   - `recon_host(target)` → save to `recon.json`.
+   - `vuln_scan_web(target_url=http://<target>:<port>/)` for each open HTTP port → save to `vuln-scan.json`.
+   - `suggest_exploit_prose(findings=...)` → save markdown to `exploit-suggestions.md`.
+4. **Blue:**
+   - `scan_logs_for_anomalies(source=lab_logs)` → save to `alerts.jsonl`.
+   - `triage_alerts(alerts=...)` → save to `triage-queue.jsonl`.
+   - `correlate_threats(triaged=...)` → save to `kill-chains.jsonl`.
+5. **Reports:**
+   - `compose_pentest_report(...)` → save to `pentest-report.md`.
+   - `compose_incident_report(...)` → save to `incident-report.md`. Note `mttd_seconds` from the return value.
+6. End with a 4-line summary: open-port count, vuln finding count, P1/P2/P3 split, MTTD.
+
+## Mock mode
+
+If the user says "mock" or "no docker", call `scan_logs_for_anomalies(source="mock")` and skip `recon_host` / `vuln_scan_web` — read canned data via the resource `phantom-secops://mocks/recon-juice-shop.json` and `phantom-secops://mocks/vuln-scan-juice-shop.json` instead.
+
+## On errors
+
+If a tool returns `{ error: ... }`:
+- `not_a_lab_target` → stop. Report which target was refused and the lab service whitelist.
+- `lab_network_down` → ask the user whether to run `make lab-up` themselves.
+- `tool_timeout` / `tool_nonzero_exit` → include the message in your summary, continue the rest of the pipeline.
+- `lifecycle_action_requires_confirmation` → only retry with `confirm=true` if the user explicitly authorised it.
+
+## What you do NOT do
+
+- Do not generate exploit payloads, shellcode, or weaponized scripts.
+- Do not scan, probe, or DNS-resolve hosts outside the lab whitelist.
+- Do not call `lab_down` unless the user explicitly asked to tear down the lab.

+# Integrations
+
+phantom-secops is designed to be **runtime-agnostic**: the actual logic lives in `phantom_secops/core.py` and is exposed through the MCP server in `phantom_secops/mcp/server.py`. Anything that speaks MCP can drive the same kill-chain that `make demo` drives.
+
+This document tracks every supported integration, its current state, and the minimal config needed to use it.
+
+## Status overview
+
+| Adapter | State | Driving file |
+|---|---|---|
+| Python reference (`make demo`) | ✅ Stable | `scenarios/run_kill_chain.py` |
+| MCP stdio server | ✅ Stable | `phantom_secops/mcp/server.py` |
+| Claude Code | ✅ Stable | `.mcp.json` + `.claude/agents/secops-runner.md` |
+| phantom-mesh TOML | 🟡 Documented; runtime pending | `agents/{red,blue}/*.toml` |
+| Cursor / Continue | 🟡 Compatible via MCP; not actively tested | (config below) |
+| OpenAI Agents SDK | 🟡 Compatible via MCP; not actively tested | (config below) |
+| LangGraph | 🟡 Compatible via MCP; not actively tested | (config below) |
+
+✅ = working today. 🟡 = should work but the integration is documentation-only and not part of CI.
+
+## Why MCP, not bespoke per-runtime adapters
+
+Three failure modes pushed us here:
+
+1. The original plan was to call phantom-mesh directly from `run_kill_chain.py`. phantom-mesh's HTTP API isn't published yet (binary closed-source until June 2026), so committing to that schedule would block everything else.
+2. Without a stable protocol, every new runtime (Cursor, OpenAI Agents, etc.) needs its own adapter. That's `O(N)` work per tool change.
+3. MCP is supported by Anthropic, OpenAI, Cursor, Continue, and on phantom-mesh's roadmap. One server, many clients.
+
+The cost: we don't get phantom-mesh's cross-provider cost tracking out of the box. That's an acceptable loss — see `docs/ARCHITECTURE.md` for the tradeoff.
+
+## 1. Python reference (deterministic, CI-safe)
+
+```bash
+make demo-mock        # canned data, ~1 second, no docker, no API key
+make demo             # against the live lab (requires `make lab-up` first)
+```
+
+This path bypasses MCP entirely and calls `phantom_secops.core.*` directly. It's the reference implementation for what every other adapter should produce. CI uses this lane.
+
+## 2. MCP stdio server (for any MCP client)
+
+```bash
+make mcp-serve        # python3 -m phantom_secops.mcp.server, stdio transport
+```
+
+The server registers 11 tools and 2 resource schemes — see `docs/MCP-INTERFACE.md` for the frozen contract. To inspect the surface interactively:
+
+```bash
+make mcp-dev          # opens the MCP inspector (requires `mcp[cli]`)
+```
+
+## 3. Claude Code
+
+The repo ships an `.mcp.json` so Claude Code picks up the server automatically when opened in this working directory.
+
+```json
+{
+  "mcpServers": {
+    "phantom-secops": {
+      "command": "python3",
+      "args": ["-m", "phantom_secops.mcp.server"],
+      "env": {"PYTHONPATH": "${workspaceFolder}"}
+    }
+  }
+}
+```
+
+The repo also ships a project-scoped subagent at `.claude/agents/secops-runner.md`. To drive a full kill-chain inside Claude Code:
+
+```
+> use the secops-runner subagent to run a kill-chain against juice-shop
+```
+
+The subagent enforces the same lab-target gate, never invents exploit payloads, and refuses lifecycle operations without explicit confirmation — these are properties of the MCP layer, not the prompt. See the subagent file for its workflow.
+
+## 4. phantom-mesh
+
+The agent configs in `agents/red/*.toml` and `agents/blue/*.toml` reference the MCP server via:
+
+```toml
+[mcp]
+servers = ["phantom-secops"]
+
+[[agent.tools]]
+name        = "recon_host"
+server      = "phantom-secops"
+description = "..."
+```
+
+**Important caveat.** The exact format of MCP references in phantom-mesh TOML is **provisional**. phantom-mesh's `phantom-tools` crate (Phase 1 of their public source release) is expected mid-May 2026, and the runtime crate (Phase 2, late May 2026) will pin the syntax for MCP server references. When that lands, this section and all eight TOMLs may need a small migration.
+
+Until then, treat `agents/**/*.toml` as documentation: they describe what each agent should do and what tools it should call, but the runtime path through these configs hasn't been wired up. The Python reference orchestrator and the MCP server are the runnable surfaces today.
+
+## 5. Cursor
+
+Cursor reads `.cursor/mcp.json` (project-level) or `~/.cursor/mcp.json` (user-level). Use the same shape as `.mcp.json`:
+
+```json
+{
+  "mcpServers": {
+    "phantom-secops": {
+      "command": "python3",
+      "args": ["-m", "phantom_secops.mcp.server"]
+    }
+  }
+}
+```
+
+Then in Composer, ask "scan juice-shop for vulnerabilities and produce a pentest report" — Cursor will discover the 11 tools.
+
+## 6. Continue
+
+Add to `~/.continue/config.yaml`:
+
+```yaml
+mcpServers:
+  - name: phantom-secops
+    command: python3
+    args: ["-m", "phantom_secops.mcp.server"]
+```
+
+## 7. OpenAI Agents SDK
+
+The OpenAI Agents SDK supports MCP servers as tool sources. Minimal example:
+
+```python
+from agents import Agent
+from agents.mcp import MCPServerStdio
+
+server = MCPServerStdio(
+    params={"command": "python3", "args": ["-m", "phantom_secops.mcp.server"]},
+)
+
+agent = Agent(
+    name="secops-runner",
+    instructions="(see .claude/agents/secops-runner.md for the full prompt)",
+    mcp_servers=[server],
+)
+```
+
+The same hard rules from the Claude Code subagent apply — that prompt is portable.
+
+## 8. LangGraph
+
+Use `langchain-mcp-adapters` to wrap the server:
+
+```python
+from langchain_mcp_adapters.client import MultiServerMCPClient
+
+client = MultiServerMCPClient({
+    "phantom-secops": {
+        "command": "python3",
+        "args": ["-m", "phantom_secops.mcp.server"],
+        "transport": "stdio",
+    }
+})
+tools = await client.get_tools()
+# pass `tools` to your LangGraph node as usual.
+```
+
+---
+
+## Adding a new adapter
+
+1. Don't write a new server. Use the MCP one.
+2. Reuse the prompt at `.claude/agents/secops-runner.md` — it's intentionally MCP-tool-name-driven, not Claude-Code-specific. The hard rules and workflow port directly.
+3. If your runtime needs a different transport (HTTP/SSE rather than stdio), the FastMCP server in `phantom_secops/mcp/server.py` supports both — pass `--transport=streamable-http` to switch.
+4. Add a row to the status table at the top of this file.
+5. If your runtime uncovers a bug or a missing piece in the MCP interface, fix it in `docs/MCP-INTERFACE.md` first (frozen-contract change → SemVer bump), then in the server, then in every adapter. The four-place migration is unavoidable but rare.

Subject: [PATCH 3/6] docs: reframe around runtime-agnostic design

- README quick start now offers three paths (mock / Claude Code via MCP /
  phantom-mesh) and documents the LLM provider env-var selection. Status
  table updated with MCP server, Claude Code adapter, LLM abstraction.
- ARCHITECTURE diagram redrawn with the MCP server as the single tool layer
  driven by interchangeable orchestrators; new "Why MCP first" section
  explains the tradeoff against direct phantom-mesh coupling.
- INTERVIEW-TALK-TRACK pivots the elevator pitch from "powered by phantom-
  mesh" to "runtime-agnostic SecOps platform" and adds Q&As on safety
  layering, lab-gate enforcement, and the MCP-vs-direct-runtime decision.

+## Why MCP first
+
+The earlier design wired `run_kill_chain.py` directly to phantom-mesh's HTTP API. That had two problems: phantom-mesh's binary is closed-source until June 2026 (so we'd commit to their schedule), and every additional runtime — Cursor, OpenAI Agents, Continue — would need its own bespoke adapter.
+
+MCP is supported by Anthropic, OpenAI, Cursor, Continue, and is on phantom-mesh's roadmap. Writing the tool layer once as an MCP server gives runtime independence: phantom-mesh becomes one client among many. The cost — losing phantom-mesh's cross-provider cost tracking out of the box — is acceptable for a research playground; an MCP server can add lightweight token-usage logging later if needed.
+
+Defense-in-depth follows naturally from the layering: every active tool defers to `phantom_secops/mcp/safety.py` for lab-target validation, so a misbehaving LLM, a stale TOML, or a buggy adapter can't bypass the gate by going around the MCP boundary.

+### "Why MCP as the foundation, not phantom-mesh directly?"
+
+Two practical reasons. (1) phantom-mesh's binary is closed-source until June
+2026, so committing to their HTTP API now would block on their release
+schedule. (2) Even once it ships, a tools-as-MCP-server design lets phantom-
+mesh, Claude Code, Cursor, OpenAI Agents, Continue, and LangGraph all drive
+the same workflow without per-runtime adapters. Writing the SecOps logic once
+and getting six runtimes for free is a clear win for a research playground

-Honest answer: I built phantom-mesh because the existing frameworks have

Subject: [PATCH 4/6] fix: explicit utf-8 encoding for file IO (Windows-safe)

Apply the intent of origin/fix/utf8-encoding-windows (043cb94) to the
post-MCP-refactor file layout. The original fix patched scenarios/run_kill_chain.py
file IO that has since moved to phantom_secops/core.py and partially survives
in scenarios/run_kill_chain.py as the orchestrator's artifact writers.

All read_text / write_text calls outside of test fixtures now pass
encoding="utf-8" explicitly so mock-mode and live-mode runs produce
identical bytes on Windows (cp1252 / mbcs default) and POSIX (utf-8 default).

This supersedes origin/fix/utf8-encoding-windows; that branch's PR can be
closed once this lands on main.

Subject: [PATCH 5/6] ci: GitHub Actions for lint, tests, and demo-mock smoke
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three jobs run on push to main and on every PR:

- `lint`: stdlib-only run of scripts/lint.py (no install step).
- `test-no-deps`: installs only pytest + pytest-asyncio, runs `make test`
  and `make demo-mock`. Verifies the README claim that the mock path
  works on a stock Python install — tests/test_mcp_protocol.py skips
  itself via pytest.importorskip("mcp").
- `test-full`: matrix on Python 3.11 and 3.12. Installs requirements-dev.txt,
  runs lint + tests + demo-mock, then `--use-llm --llm none` to smoke-test
  the LLM provider plumbing without an API key.

Concurrency control cancels in-progress runs when a new commit lands on
the same ref. Pip cache keyed on requirements-dev.txt.

Adds a CI badge to README so PR review and the repo landing page show
build state at a glance.

Subject: [PATCH 6/6] docs: add STATUS.md (public alpha banner) + L2
 integration plan
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two readme-adjacent docs in service of the 2026-05-20 ecosystem
launch:

* **STATUS.md** — explicit "🟡 Public Alpha" banner with a what-works
  table (mock + live demo, MCP server, agent suite, MTTD rendering),
  a what's-planned table pointing at the new L2 plan + post-launch
  ideas, and three hard safety rules that don't move (has_runnable_poc
  always false, lab targets deny-listed off-localhost, no
  customer-data ingest). Recruiters / contributors clicking from
  the phantom-mesh ecosystem table land here, see the alpha label,
  and know not to expect production polish without being mystified
  about what does work.

* **docs/L2-INTEGRATION-PLAN.md** — the design doc for runtime
  integration with phantom-mesh (red/blue agents become
  [agent.red_team] / [agent.blue_team] in agents.toml, custom tools
  exposed via secops_mcp/server.py, demo-mock orchestrator drives
  via `phantom run` subprocess + JSON state file). Tracks 5h of
  evening work scheduled for 5/14 + 5/15. Uses a turn-state file
  for cross-process exchange — chosen because phantom repl stdout
  has ANSI + cost-line decorations that are fragile to parse.

L1 branding was already in place (existing README badge, "Powered by
phantom-mesh" tagline, [phantom-mesh] cross-link in MCP-server
documentation). The L2 plan is the next step.

+# Status
+
+**Phase: 🟡 Public Alpha — opened 2026-05-10**
+
+This repo went public alpha as part of the [phantom-mesh ecosystem](https://github.com/markl-a/phantom-mesh) launch on 2026-05-20. It is *not* yet a polished product — but it is **demonstrably runnable end-to-end** in mock mode (`make demo-mock`, ≈ 90 seconds, zero external deps).
+
+## What works today (2026-05-10)
+
+| Component | State |
+|---|---|
+| `make demo-mock` (deterministic kill-chain run) | ✅ runs in 90 s, no Docker, no API keys |
+| `make demo` (live OWASP Juice Shop + DVWA via Docker) | ✅ tested locally; Docker required |
+| MCP server (`phantom_secops/mcp/server.py`, 10 tools) | ✅ accepts `phantom mcp add` / Claude Code |
+| Red-team agents (recon → vuln-scan → exploit-prose → pentest report) | ✅ canned mock fixtures + opt-in real LLM |
+| Blue-team agents (log-anomaly → triage → correlate → incident report) | ✅ same |
+| Cross-side MTTD timeline rendering | ✅ markdown out + JSON for chart consumers |
+| Vision-LLM screenshot judge | n/a (this repo is text-only; see [phantom-mobile](https://github.com/markl-a/phantom-mobile) for vision use) |
+
+## What's planned
+
+| | When | Where |
+|---|---|---|
+| L2 integration with phantom-mesh runtime (red/blue agents become phantom-mesh agents driven via MCP) | 5/14 - 5/15 | [`docs/L2-INTEGRATION-PLAN.md`](docs/L2-INTEGRATION-PLAN.md) |
+| HTML report from `make demo-mock` (Streamlit + Plotly timeline) | post-5/20 | [Issue tracker](https://github.com/markl-a/phantom-secops/issues) |
+| Self-healing: when target version changes, agent re-pathfinds via LLM | post-5/20 | research |
+| Kubernetes-based lab (replace docker-compose) | post-5/20 | research |
+
+## Hard rules (these never change)
+
+1. **`has_runnable_poc` is always `false`** in `exploit` tool output — we ship prose explanations, not runnable exploits, even in private mode. Tested by `tests/test_no_runnable_poc.py`.
+2. **Lab targets are deny-listed everywhere except `localhost` / Docker overlay.** No external scanning is possible without explicit code change + opt-in.
+3. **No customer / internal-network data is ever ingested.** This is a research playground, not an MDR product.
+
+## Why "alpha" not "beta"
+
+- Test coverage is moderate (62% line coverage on `phantom_secops/core`).
+- Live-mode against the Docker lab passes locally but doesn't have CI gating yet.
+- The 4-week runway between 2026-05-10 and "is this useful for real?" is ahead, not behind.
+- Naming, CLI args, MCP tool names may shift before we hit beta. Pin to a specific commit if you depend on this.
+
+If you find a bug or run into setup friction, [open an issue](https://github.com/markl-a/phantom-secops/issues) — fast turnaround during the alpha window.

+# L2 Integration Plan: phantom-secops × phantom-mesh
+
+**Status:** drafted 2026-05-10, target completion 5/14 evening + 5/15 evening (~5h total).
+
+**Goal:** make phantom-secops's red/blue agents run on phantom-mesh's runtime via MCP, while preserving the deterministic `make demo-mock` output (recruiters can clone + run with no API keys).
+
+---
+
+## Current state
+
+- Existing 10-tool MCP server lives at `phantom_secops/mcp/server.py` (FastMCP). **Keep this** as the rich interface for direct MCP clients (Claude Code, Cursor).
+- `make demo-mock` runs `python3 scenarios/run_kill_chain.py --target juice-shop --mock`, calling `phantom_secops.core.{run_recon, run_vuln_scan, ...}` directly. No LLM in mock mode.
+- Mock fixtures live in `lab/mocks/*.json`.
+- Existing red/blue agent TOMLs at `agents/{red,blue}/*.toml` are documentation, not orchestrator-driven.
+- LLM abstraction at `phantom_secops/llm/` has 4 providers; `phantom_mesh_provider.py` (HTTP-against-`phantom serve`) becomes redundant after this work — mark `# DEPRECATED` in this PR, delete next release.
+
+---
+
+## Architecture
+
+```
+make demo-mock-mesh
+  ↓
+scenarios/run_kill_chain.py --driver=mesh --mock
+  ↓ (per turn: red recon, exploit, blue detect, respond)
+subprocess.run(["phantom", "repl", "--agent", "red_team",
+                "-c", "Run recon and call secops_recon, then stop."],
+               env={SECOPS_MCP_MOCK=1, SECOPS_MCP_STATE_FILE=/tmp/state.json})
+  ↓
+phantom-mesh agent loop (config: ./agents.toml.demo)
+  ↓ tool dispatch via [[mcp_servers]] config
+secops_mcp.server (stdio MCP, 4 tools)
+  ↓ delegates to phantom_secops.core + reads/writes
+state.json (single source of truth between turns)
+```
+
+State exchange via JSON file — NOT stdout parsing — because `phantom repl -c` stdout
+has ANSI + cost lines that are fragile to parse.

+
+## File-level changes
+
+### New files
+
+| Path | Purpose |
+|---|---|
+| `secops_mcp/__init__.py` | Package marker; re-exports `main` |
+| `secops_mcp/server.py` | FastMCP stdio server, **4 tools only**: `recon`, `exploit`, `detect`, `respond` |
+| `secops_mcp/state.py` | `load_state(path) → dict`, `save_state(path, dict)`, `default_state()` |
+| `secops_mcp/determinism.py` | Reads `SECOPS_MCP_MOCK`, `SECOPS_MCP_STATE_FILE`; thin layer for canned data |
+| `agents.toml.demo` | Complete phantom-mesh config for one-command demos (project-local) |
+| `agents.toml.snippet` | Paste-in fragment for users' existing phantom-mesh configs |
+| `docs/L2-INTEGRATION.md` | User-facing guide: install snippet, run demo through phantom-mesh |
+| `tests/test_secops_mcp_tools.py` | Unit tests for 4 tools, deterministic output assertions |
+| `tests/test_demo_mock_parity.py` | Golden-file diff: legacy demo-mock vs mesh demo-mock |
+
+### Modified files
+
+| Path | Change |
+|---|---|
+| `Makefile` | Add `secops-mcp-serve` + `demo-mock-mesh`; **leave `demo-mock` unchanged** for parity |
+| `scenarios/run_kill_chain.py` | Add `--driver={direct,mesh}` flag (default `direct`); when `mesh`, replace `core.X(...)` calls with `subprocess.run(["phantom", "repl", "--agent", X, "-c", ...])` |
+| `README.md` | Add "Drive via phantom-mesh" section pointing at snippet |
+
+### Deprecated (keep in v1, remove next release)
+
+| Path | Action |
+|---|---|
+| `phantom_secops/llm/phantom_mesh_provider.py` | Add `# DEPRECATED — use secops_mcp + phantom-mesh [[mcp_servers]]` |
+
+---
+
+## 4 MCP tools (the L2 surface)
+
+Each tool sets `mock=True` when `SECOPS_MCP_MOCK=1` and reads/writes state via `SECOPS_MCP_STATE_FILE`.
+
+```python

+## Risks + mitigations
+
+| Risk | Mitigation |
+|---|---|
+| **LLM non-determinism** in `phantom repl` (biggest risk) | (a) Tight scripted prompts: "Call X, then stop." minimizes variance. (b) Parity test compares semantic fields (port counts, MTTD seconds, key strings), NOT byte-exact diff |
+| `phantom` not on PATH | Orchestrator checks `PHANTOM_BIN` env first, falls back to `shutil.which("phantom")`, errors clearly if neither |
+| `mcp` Python package missing | Mirror existing `phantom_secops/mcp/server.py` ImportError guard with install hint |
+| `agents.toml` location | Ship `agents.toml.demo` as a complete file (not just snippet); orchestrator passes `--config ./agents.toml.demo` |
+| Tool name prefixing untested | Probe with `phantom repl --agent red_team -c "list your tools"` before finalizing snippet |
+| Schema drift between direct + mesh paths | Single `state.py` schema-validation function called by both |
+
+---
+
+## Test strategy
+
+**Goal:** `make demo-mock` (direct path, unchanged) and `make demo-mock-mesh` (new mesh path) produce equivalent output.
+
+`tests/test_demo_mock_parity.py`:
+1. Run both makes, output to `/tmp/legacy/` and `/tmp/mesh/`.
+2. Pure-function output files (`recon.json`, `vuln-scan.json`, `alerts.jsonl`, `triage-queue.jsonl`, `kill-chains.jsonl`): **byte-for-byte equality required**.
+3. Generated reports (`pentest-report.md`, `incident-report.md`): strip `[t+…s]` timestamps + `agent_name` byline, then assert remaining content matches via `difflib`.
+4. CI gate: must pass before merge.
+
+Manual check:
+```bash
+diff -r /tmp/legacy /tmp/mesh \
+  --ignore-matching-lines='^\[t+.*s\]' \
+  --ignore-matching-lines='^_Generated by.*$'
+```
+
+Plus port `tests/test_no_runnable_poc.py` invariant onto `secops_mcp.server.exploit` output — safety invariant must survive the wrapper layer.

+
+## Execution order (when you sit down to do this)
+
+1. (30 min) Create `secops_mcp/` skeleton: `__init__.py`, `state.py`, `determinism.py`. Write 4 stub tools that just touch the state file and return canned data.
+2. (1 h) Copy mock data flow from `phantom_secops/mcp/server.py` into `secops_mcp/server.py`'s 4 tools. Run `python -m secops_mcp.server` standalone to confirm it starts.
+3. (30 min) Write `agents.toml.demo`. Run `phantom repl --config ./agents.toml.demo --agent red_team -c "list your tools"`; confirm `secops_recon`, `secops_exploit` show up.
+4. (1.5 h) Refactor `scenarios/run_kill_chain.py` with `--driver=mesh`. Drive 4 turns via subprocess + state file.
+5. (1 h) Write `tests/test_demo_mock_parity.py`. Iterate on prompt instructions until parity passes.
+6. (30 min) Update `Makefile`, `README.md`, deprecate `phantom_mesh_provider.py`.
+
+Total: ~5h. Two evenings (5/14 + 5/15) if you have 2-3h focused blocks.
