mcp-file-system-lmstudio

A Model Context Protocol (MCP) server that exposes a local LM Studio model as tools. It talks to LM Studio's OpenAI-compatible API, so any model loaded in LM Studio can be queried from an MCP client.

Features

• lmstudio_chat — send a prompt (or full multi-turn message history) to the local model and get its response back

• lmstudio_list_models — list all models currently available on the LM Studio server

• No API keys required — everything runs locally against your own LM Studio instance

Related MCP server: LM Studio MCP Bridge

Requirements

• Node.js >= 18 (uses built-in fetch)

• A running LM Studio server with at least one model loaded

Start the LM Studio server from its UI (Developer tab → Start Server). By default it listens on http://localhost:1234.
