(Model Context Protocol): - Per-user MCP server catalog with connection tiers and OAuth (PKCE, autodiscovery) support - MCP client/service/token-manager and OAuth discovery service - MCP tool factory and run-connection bindings for the agent engine - Prisma models and migrations for MCP servers, tools, tiers, and OAuth - mcp-servers dashboard pages (connect, tools, tiers, calls, info tabs) and useMcp hook - Shared MCP zod schemas and tests Governance: - Governance MCP admin pages (import dialog, admin calls sheet) - Token governance and policy updates - Sidebar navigation and admin MCP controller Includes unit tests across API, shared schemas, and web. --- docker-compose.dev.yml | 26 + docker-compose.prod.yml | 31 + packages/api/package.json | 1 + .../migration.sql | 89 +++
