    About this skill

    MCP Doctor — Model Context Protocol Health & Schema Linter

    Frustrated by AI coding assistants silently failing when invoking Model Context Protocol (MCP) servers due to subtle JSON syntax errors, missing executables on PATH, or tool name collisions?

    MCP Doctor is a production-grade diagnostic CLI and schema linter for the open Model Context Protocol standard. It inspects your Claude Desktop, Cursor, Windsurf, Antigravity, and custom agent configurations in milliseconds.

    ⚡ Key Capabilities:

    • Schema & Syntax Linting: Validates JSON compliance and ensures required command, args, and env attributes match the official MCP specification.
    • Binary & PATH Resolution: Instantly detects if uvx, npx, python3, or custom binaries are missing or inaccessible before an agent crashes.
    • Credential & Placeholder Watchdog: Flags unconfigured API keys and dummy placeholder tokens (YOUR_KEY_HERE, sk-ant-xxx).
    • Cross-Config Collision Detection: Identifies duplicated server names across multiple configuration files.
    • Live JSON-RPC Handshake Probe: Performs a non-destructive stdio handshake (initialize call with strict timeout) to prove connectivity without side effects.
    • Agent-Ready JSON Output: Seamlessly feeds structured diagnostics to autonomous agent orchestrators.

    📦 What's Included:

    • scripts/mcp_doctor.py — Production CLI diagnostic linter
    • scripts/test_mcp_doctor.py — Automated test suite with 100% pass rate
    • references/mcp_doctor_guide.md — CLI reference & troubleshooting matrix
    • references/json_rpc_schema_spec.md — Formal 2024-11-05 MCP spec summary
    • SKILL.md — Lean Core prompt rules (< 40 lines) for Claude Code, Cursor, and Antigravity
