Environment variables

Variables the server reads at startup.

Name	Required	Description
`HOUTINI_LM_ENDPOINT_URL`	No	Base URL of the OpenAI-compatible API endpoint (e.g. http://localhost:1234, https://openrouter.ai/api). Legacy alias: LMSTUDIOURL.
`HOUTINI_LM_API_KEY`secret	No	Bearer token for API authentication (no auth if blank). Legacy aliases: LMSTUDIOPASSWORD, LMPASSWORD, OPENROUTERAPI_KEY.
`HOUTINI_LM_MODEL`	No	Model identifier to use for requests (auto-detected if not set). Legacy alias: LMSTUDIOMODEL.
`HOUTINI_LM_PROVIDER`	No	Optional provider override: 'openrouter' forces OpenRouter-specific handling (attribution headers, reasoning.exclude, no inference serialisation)…

About Lm

Houtini LM is an MCP server that lets Claude (or any MCP client) hand bounded work to another model - a local LLM on your GPU, OpenAI's latest GPT models, a LiteLLM router, OpenRouter or a cheap cloud API - while you carry on working in the AI platform you already like. It cuts your token bill, and it gives you a second model to review your code whenever you want one.

What is Lm?

How do I install the Lm MCP server?

Add the command npx -y @houtini/lm to your MCP client: put it in claude_desktop_config.json for Claude Desktop, run claude mcp add for Claude Code, or add it to .cursor/mcp.json (Cursor) or .vscode/mcp.json (VS Code). The snippets on this page are ready to paste.

Is Lm free?

The server is open source under the Apache-2.0 license, so running it is free. It needs credentials (HOUTINI_LM_API_KEY) for the service it connects to, which may require a paid account.
