CloudBridge UY Date: Mon, 21 Sep 2026 15:50:16 -0300 Subject: [PATCH 12/61] implement V4: unreached function in conformance_tests and enrich all contract samples for zero unreached paths - add pure unreached and unreached_collect following strip/loose walker conventions with visited guard for recursion - update 41 samples to populate optional fields with non-nulls and ensure arrays have elements

With --discovery or MCPTOOLS_DISCOVERY=true, tools/list returns only find_tools. tools/call still dispatches every tool by name, and find_tools still ranks and attaches schemas from the full registry. The default list is unchanged. The gate is a pure function, listed_tools, in the shell crate because Tool is a shell-crate type. The flag sits on Global beside --verbose, so stdio and SSE both honor it through the shared handle_request. The find_tools description gains one sentence that tells the agent the returned tools are callable by name even when unlisted. Test spawners remove MCPTOOLS_DISCOVERY from the child environment so an exported value cannot break the full-list assertions. The discovery contract test also removes the Jev variables and asserts the local backend, which keeps it offline. Deliberate simplifications: - bool flag, not an enum; no third list mode exists. - The flag is global, so it appears in every subcommand's help and is inert outside mcp. - The env var accepts only true or false; any other value is a clap parse error. - Host reachability is out of scope. Hosts that declare only listed tools to the model, such as Claude Code, cannot yet call the found tool. A planned execute command owns that gap. - No SSE-specific test; SSE shares handle_request with stdio. - The contract test proves dispatch with jira_query_list, which runs offline. linear_issue_get needs credentials and was not run live.

Core gains pure sandbox types: Limits (30s, 64 MiB, 256 KiB defaults), a byte-capped LogBuffer, Output, and the SandboxError enum (Timeout, OutputLimit, Js). The runner builds a fresh AsyncRuntime per call inside spawn_blocking plus Handle::current().block_on, applies set_memory_limit, binds a __log host function, and evals a prelude that maps console.{log,info,warn,error,debug} into it. User code runs under promise-mode eval; the completion value is unwrapped from the {value} wrapper, awaited when it is itself a promise so rejections like failed module loads surface, then JSON-stringified into serde_json::Value (undefined and functions become null). JS exceptions are read from ctx.catch() as name/message; other rquickjs errors and join errors map to Js {name: Error}. --- Cargo.lock | 51 ++++++++ Cargo.toml | 1 + crates/core/src/lib.rs | 1 + crates/core/src/sandbox.rs | 83 +++++++++++++ crates/mcptools/Cargo.toml | 1 + crates/mcptools/src/main.rs | 1 + crates/mcptools/src/sandbox.rs | 213 +++++++++++++++++++++++++++++++++ 7 files changed, 351 insertions(+) create mode 100644 crates/core/src/sandbox.rs create mode 100644 crates/mcptools/src/sandbox.rs diff --git a/Cargo.lock b/Cargo.lock index 610ebf3..2712b6d 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -134,6 +134,17 @@ dependencies = [ "pin-project-lite", ] +[[package]] +name = "async-lock" +version = "3.4.2" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "290f7f2596bd5b78a9fec8088ccd89180d7f9f55b94b0576823bbbdc72ee8311" +dependencies = [ + "event-listener", + "event-listener-strategy", + "pin-project-lite", +] + [[package]] name = "atomic-waker" version = "1.1.2" @@ -2224,6 +2235,7 @@ dependencies = [ "rand 0.8.5", "regex", "reqwest 0.12.28", + "rquickjs", "rusqlite", "schemars", "serde", @@ -3022,6 +3034,15 @@ version = "0.8.9" source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "a96887878f22d7bad8a3b6dc5b7440e0ada9a245242924394987b21cf2210a4c" +[[package]] +name = "relative-path" +version = "2.0.1" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "bca40a312222d8ba74837cb474edef44b37f561da5f773981007a10bbaa992b0" +dependencies = [ + "serde", +] + [[package]] name = "reqwest" version = "0.12.28" @@ -3117,6 +3138,36 @@ dependencies = [ "windows-sys 0.52.0", ] +[[package]] +name = "rquickjs" +version = "0.14.0" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "a0a22bf72f515cc4189dd7c63d016f6de92a11eee98ddf7dd64794198f6eb34e" +dependencies = [ + "rquickjs-core", +] + +[[package]] +name = "rquickjs-core" +version = "0.14.0" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "6657979a24d543e5fc66f32cef2f47ca82ce8eb55cec5f7d59a12b7b570bbf24" +dependencies = [ + "async-lock", + "hashbrown 0.17.1", + "relative-path", + "rquickjs-sys", +] + +[[package]] +name = "rquickjs-sys" +version = "0.14.0" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "cee271d0eeba64f0915b846cb7ae02e16faf3dfdffdca91731101d9d30fe3423" +dependencies = [ + "cc", +] + [[package]] name = "rusqlite" version = "0.34.0" diff --git a/Cargo.toml b/Cargo.toml index d84170d..691f328 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -65,3 +65,4 @@ tera = "1.20.0" toml = "0.8" schemars = "1.2" jsonschema = "0.56" +rquickjs = { version = "0.14", features = ["futures"] } diff --git a/crates/core/src/lib.rs b/crates/core/src/lib.rs index 8a090ea..c914142 100644 --- a/crates/core/src/lib.rs +++ b/crates/core/src/lib.rs @@ -87,5 +87,6 @@ pub mod llm_stream;

on deadline it records StopReason::Timeout and raises the uncatchable interrupt exception, so try/catch and regex backtracking cannot evade it - __log sets StopReason::OutputLimit and throws a JS RangeError when LogBuffer::push rejects; the stop cell, not the exception, is the enforcement (exceptions are catchable cosmetics) - eval drive wrapped in tokio::time::timeout for the never-resolving promise case, where no bytecode runs and the interrupt never fires - mapping order in run_inner: stop cell, then elapsed, then the JS exception path, then Output::check_size on the built output - Output::check_size (core, pure): sum of log bytes plus serialized result length must stay within the cap;

Dispatch goes through handle_tools_call; plain Error exceptions carry code and data. mcp::tools visibility widened to pub(crate) so sandbox::bindings can reach it. Top-level return scripts parse-fail as QuickJS eval scripts ('return not in a function'); eval retries once wrapped in an uninvoked-async-arrow body, keyed on that exact parse message so runtime-thrown SyntaxErrors never re-run side effects. Completion value then rides the existing {value} wrapper and into_promise path.

A wiremock stub serves the three Jira REST routes from fixtures under tests/fixtures/jira/. Assertions: structuredContent logs == ["3"], result null, no issue keys in the response payload, and exactly 3 PUTs on the update route in the stub request log. The script throws on partial_failure so a 404 on the update route fails the logs assertion instead of passing silently. wiremock 0.6.5 added to mcptools dev-dependencies. --- Cargo.lock | 62 +++++++++++++++ crates/mcptools/Cargo.toml | 1 + crates/mcptools/tests/e2e_jira_chain.rs | 78 +++++++++++++++++++ .../mcptools/tests/fixtures/jira/search.json | 30 +++++++ .../mcptools/tests/fixtures/jira/sprint.json | 14 ++++ .../mcptools/tests/fixtures/jira/update.json | 1 + 6 files changed, 186 insertions(+) create mode 100644 crates/mcptools/tests/e2e_jira_chain.rs create mode 100644 crates/mcptools/tests/fixtures/jira/search.json create mode 100644 crates/mcptools/tests/fixtures/jira/sprint.json create mode 100644 crates/mcptools/tests/fixtures/jira/update.json diff --git a/Cargo.lock b/Cargo.lock index 2712b6d..fd444a3 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -122,6 +122,16 @@ version = "1.0.101" source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "5f0e0fee31ef5ed1ba1316088939cea399010ed7731dba877ed44aeb407a75ea" +[[package]] +name = "assert-json-diff" +version = "2.0.2" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "47e4f2b81832e72834d7518d8487a0396a28cc408186a2e8854c0f98011faf12" +dependencies = [ + "serde", + "serde_json", +] + [[package]] name = "async-channel" version = "2.5.0" @@ -738,6 +748,24 @@ version = "2.10.0" source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "d7a1e2f27636f116493b8b860f5546edb47c8d8f8ea73e1d2a20be88e28d1fea" +[[package]] +name = "deadpool" +version = "0.12.3" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "0be2b1d1d6ec8d846f05e137292d0b89133caf95ef33695424c09568bdd39b1b" +dependencies = [ + "deadpool-runtime", + "lazy_static", + "num_cpus", + "tokio", +] + +[[package]] +name = "deadpool-runtime" +version = "0.1.4" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "092966b41edc516079bdf31ec78a2e0588d1d0c08f78b91d8307215928642b2b" + [[package]] name = "deranged" version = "0.5.8" @@ -2252,6 +2280,7 @@ dependencies = [ "tree-sitter-rust", "tree-sitter-typescript", "urlencoding", + "wiremock", ] [[package]] @@ -2484,6 +2513,16 @@ dependencies = [ "autocfg", ] +[[package]] +name = "num_cpus" +version = "1.17.0" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "91df4bbde75afed763b708b7eee1e8e7651e02d97f6d5dd763e89367e957b23b" +dependencies = [ + "hermit-abi", + "libc", +] + [[package]] name = "number_prefix" version = "0.4.0" @@ -4935,6 +4974,29 @@ version = "0.0.19" source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "d135d17ab770252ad95e9a872d365cf3090e3be864a34ab46f48555993efc904" +[[package]] +name = "wiremock" +version = "0.6.5" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "08db1edfb05d9b3c1542e521aea074442088292f00b5f28e435c714a98f85031" +dependencies = [ + "assert-json-diff", + "base64 0.22.1", + "deadpool", + "futures", + "http", + "http-body-util", + "hyper", + "hyper-util", + "log", + "once_cell", + "regex", + "serde", + "serde_json", + "tokio", + "url", +] + [[package]] name = "wit-bindgen" version = "0.51.0" diff --git a/crates/mcptools/Cargo.toml b/crates/mcptools/Cargo.toml index 380452e..f14c8ef 100644 --- a/crates/mcptools/Cargo.toml +++ b/crates/mcptools/Cargo.toml @@ -53,6 +53,7 @@ tempfile = "3.8" [dev-dependencies] jsonschema = { workspace = true } +wiremock = "0.6" [package.metadata.cargo-machete] ignored = [] diff --git a/crates/mcptools/tests/e2e_jira_chain.rs b/crates/mcptools/tests/e2e_jira_chain.rs new file mode 100644 index 0000000..0703ca3 --- /dev/null +++ b/crates/mcptools/tests/e2e_jira_chain.rs @@ -0,0 +1,78 @@ +mod common;

Flags are flattened into mcp::App with global = true, so both 'mcp --discovery stdio' and 'mcp stdio --discovery' parse; MCPTOOLS_DISCOVERY / MCPTOOLS_CODE_MODE env vars still apply. Flags thread by value from mcp::run through the stdio and sse runners into handle_request, the list and call handlers, and the sandbox Bindings, so a bound find_tools call inside execute inherits them. Breaking: 'mcptools --discovery mcp stdio' no longer parses; the flag must come at or after 'mcp'. Deliberate, accepted. code_mode parses but nothing consumes it yet; the tools/list gate still branches only on discovery. Both flags use BoolishValueParser: clap's default bool parser rejects 'MCPTOOLS_DISCOVERY=1', only 'true'/'false', and the acceptance demo uses =1. --- crates/mcptools/src/main.rs | 8 ------ crates/mcptools/src/mcp/cli.rs | 24 ++++++++++++++++ crates/mcptools/src/mcp/mod.rs | 17 +++++++---- crates/mcptools/src/mcp/sse.rs | 14 ++++++---- crates/mcptools/src/mcp/stdio.rs | 4 +-- crates/mcptools/src/mcp/tools/execute.rs | 27 +++++++++++++++--- crates/mcptools/src/mcp/tools/find_tools.rs | 7 ++++- crates/mcptools/src/mcp/tools/mod.rs | 31 +++++++++++++-------- crates/mcptools/src/sandbox.rs | 5 ++++ crates/mcptools/src/sandbox/bindings.rs | 15 +++++++++- 10 files changed, 114 insertions(+), 38 deletions(-) diff --git a/crates/mcptools/src/main.rs b/crates/mcptools/src/main.rs index d8bdecb..aad1b36 100644 --- a/crates/mcptools/src/main.rs +++ b/crates/mcptools/src/main.rs @@ -44,14 +44,6 @@ pub struct Global { #[clap(long, env = "MCPTOOLS_VERBOSE", global = true, default_value = "false")] pub verbose: bool, - #[clap( - long, - env = "MCPTOOLS_DISCOVERY", - global = true, - default_value = "false" - )] - pub discovery: bool, - #[clap( long, env = "MCPTOOLS_EXECUTE_TIMEOUT_SECS", diff --git a/crates/mcptools/src/mcp/cli.rs b/crates/mcptools/src/mcp/cli.rs index 12606e6..2e03572 100644 --- a/crates/mcptools/src/mcp/cli.rs +++ b/crates/mcptools/src/mcp/cli.rs @@ -1,7 +1,31 @@ +#[derive(Clone, Copy, Debug, PartialEq, Eq, clap::Args)] +pub struct ServeFlags { + #[clap( + long, + env = "MCPTOOLS_DISCOVERY", + global = true, + default_value = "false", + value_parser = clap::builder::BoolishValueParser::new() + )] + pub discovery: bool, + + #[clap( + long, + env = "MCPTOOLS_CODE_MODE", + global = true, + default_value = "false", + value_parser = clap::builder::BoolishValueParser::new() + )] + pub code_mode: bool, +} + #[derive(Debug, clap::Parser)] #[command(name = "mcp")] #[command(about = "Model Context Protocol server")] pub struct App { + #[clap(flatten)] + pub flags: ServeFlags, + #[command(subcommand)] pub command: Commands, } diff --git a/crates/mcptools/src/mcp/mod.rs b/crates/mcptools/src/mcp/mod.rs index c5621f4..9d0671f 100644 --- a/crates/mcptools/src/mcp/mod.rs +++ b/crates/mcptools/src/mcp/mod.rs @@ -4,7 +4,7 @@ mod sse;
