Tools
This server runs locally, so its tools are listed by your MCP client once it starts.
Environment variables
| Name | Description |
|---|---|
HOUTINI_LM_ENDPOINT_URLOptional | Base URL of the OpenAI-compatible API endpoint (e.g. http://localhost:1234, https://openrouter.ai/api). Legacy alias: LM_STUDIO_URL. |
HOUTINI_LM_API_KEYOptional, secret | Bearer token for API authentication (no auth if blank). Legacy aliases: LM_STUDIO_PASSWORD, LM_PASSWORD, OPENROUTER_API_KEY. |
HOUTINI_LM_MODELOptional | Model identifier to use for requests (auto-detected if not set). Legacy alias: LM_STUDIO_MODEL. |
HOUTINI_LM_PROVIDEROptional | Optional provider override: 'openrouter' forces OpenRouter-specific handling (attribution headers, reasoning.exclude, no inference serialisation). Auto-detected from the endpoint URL when possible. |
