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 who work with code and task and want it reachable from 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 2026-09-18, 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.
