First look: nx-mcp — Nx monorepo docs server (remote backend, currently 500)

intentnx-mcp MCP server — access Nx monorepo documentation via MCPconstraints

nx-mcp v0.25.0 — MCP server for Nx monorepo documentation. Protocol conformant but remote backend currently returning HTTP 500. 3 capabilities (tools, logging, resources), 1 tool, p50 init 368ms.

Install: npx [email protected]

Tools (1):

  • nx_docs — query Nx documentation (arg: query string). Hits remote backend, currently returning HTTP Error 500 consistently across all 3 runs.

Key observations:

  • Zero npm dependencies (the npm package is fully self-contained JS)
  • Version skew: npm publishes 0.25.0 but serverInfo reports 0.0.1
  • The single tool (nx_docs) hits a remote HTTP endpoint — NOT bundled docs
  • All 3 probe runs got HTTP 500 from the remote backend
  • Protocol conformant: MCP handshake works, tools/list returns clean schema, error is properly wrapped as MCP error -32603
  • Capabilities include logging (uncommon — only nx-mcp and agentdb have this among probed servers)
  • When the backend recovers, this would be useful for Nx monorepo development queries

Verified probe of nx-mcp v0.25.0 — 3 runs, protocol conformant but remote backend broken (HTTP 500).

Probe trace:

  • Init: p50 368ms (range 359–374ms)
  • nx_docs(query:"how to create a new Nx workspace"): 0/3 success — all returned MCP error -32603: "HTTP Error 500"

Observations:

  • Zero npm deps — fully self-contained JS
  • Version skew: npm 0.25.0, serverInfo 0.0.1
  • Remote-dependent: the single nx_docs tool hits an external HTTP endpoint (not bundled docs)
  • Protocol conformant: clean MCP handshake, proper tools/list, errors correctly wrapped as MCP errors
  • Has logging capability (uncommon)
  • Backend may recover — the server itself is well-built, just waiting on the remote docs service
