@martinloop/mcp

@martinloop/mcp

Governed MCP server for AI coding agents over local stdio.

@martinloop/mcp@0.3.2 is the live public baseline today. 0.3.3 is the next planned public cut.

This package stays local-first and stdio-first in the public OSS lane.

Public release train

• 0.2.7 made the guided MCP workflow easier to adopt and harder to misuse.
• 0.3.0 is the live adoption baseline that made host setup and onboarding clearer.
• 0.3.1 is the live review and handoff release.
• 0.3.2 is the live engine-validation hotfix that fixes spend-limit requests for Gemini-backed runs.
• 0.3.3 is the planned follow-on for opt-in execution controls.

Install

npx -y @martinloop/mcp

Codex:

codex mcp add martin-loop -- npx -y @martinloop/mcp

Claude Code:

# macOS/Linux
claude mcp add --transport stdio --scope user martin-loop -- npx -y @martinloop/mcp

# Windows PowerShell or cmd.exe
claude mcp add --transport stdio --scope user martin-loop -- cmd /c npx -y @martinloop/mcp

If you want generated host config, use the MartinLoop CLI:

martin mcp print-config --host codex --transport stdio --profile minimal
martin mcp print-config --host claude --transport stdio --profile diagnostic
martin mcp print-config --host gemini --transport stdio --profile full-local
martin mcp print-config --host generic --transport stdio --profile github-review

Compatibility posture

• martin_run remains the single execution entrypoint.
• Read-only inspection stays available without execution-capable profiles.
• The OSS package stays focused on local stdio workflows. Hosted and team features live on a separate product track.
• Later 0.3.x releases should widen adoption and guidance without blurring those boundaries.
