@martinloop/mcp 0.3.2

0.3.2 is a validation hotfix for the standalone MartinLoop MCP server.

Release story

Fix a tool-input validation gap that could reject valid spend-limit requests.

What changed

  • martin_run, martin_preflight, and martin_doctor now accept engine: "gemini", matching the engines the run loop already supports.
  • Previously, any call that combined engine: "gemini" with a budget field (for example maxUsd) was rejected with Invalid engine., even though Gemini-backed runs were otherwise fully supported.
  • No other tool inputs, defaults, or behaviors changed.

Why this matters

If you set a spend limit or budget for a Gemini-backed run through the MCP tools, that request now validates correctly instead of being rejected.

Out of scope

  • opt-in execution controls (planned for 0.3.3)
  • new tools or schema fields
  • changes to budget enforcement behavior

Release gate

Setting a spend limit on any supported engine - Claude, Codex, or Gemini - through martin_run, martin_preflight, or martin_doctor must validate successfully.
