Lm MCP Server

I built this because I kept leaving Claude Code running overnight on big refactors and the token bill was painful. A huge chunk of that spend goes on bounded tasks any decent model handles fine - generating boilerplate, code review, commit messages, format conversion. Stuff that doesn't need Claude's reasoning or tool access. Its 4 documented tools cover code, task.

People connecting coding agent tools to Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.

01 · Install Lm

before you install - you'll need

Set HOUTINI_LM_ENDPOINT_URL, HOUTINI_LM_API_KEY, HOUTINI_LM_MODEL before connecting.

Claude Code

claude mcp add houtini-ai-lm -- npx -y @houtini/lm

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "houtini-ai-lm": {
      "command": "npx",
      "args": [
        "-y",
        "@houtini/lm"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license Apache-2.0 - declared in the repository

npm package @houtini/lm - the @houtini scope differs from the repo owner (houtini-ai); confirm it's the project's official package

registry namespace io.github.houtini-ai is GitHub-verified and matches the repo owner

03 · What Lm can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

An agent gets 4 documented tools spanning code, task, including custom_prompt, code_task, code_task_files, list_models.

06 · Lm FAQ

Is Lm still maintained?

Yes - as of 2026-08-25, its last commit was 2026-08-15. We re-verify nightly.

What can Lm do?

An agent gets 4 documented tools spanning code, task, including custom_prompt, code_task, code_task_files, list_models.

How do I install Lm?

Run `npx -y @houtini/lm`. The README documents 3 environment variables (HOUTINI_LM_ENDPOINT_URL, HOUTINI_LM_API_KEY, HOUTINI_LM_MODEL) to set first. Set HOUTINI_LM_ENDPOINT_URL, HOUTINI_LM_API_KEY, HOUTINI_LM_MODEL before connecting. You can also paste the ready-made client config above.

Does Lm run locally?

Yes - it's a stdio server: it runs on your machine (via npx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
