Unleash MCP Server is a Model Context Protocol bridge that enables LLM applications to interact with the Unleash feature flag system. It exposes flag data to LLMs, supports checking flag status, creating and updating flags, and listing projects. Acting as a middle layer between the LLM client and the Unleash API, it translates MCP requests into Unleash API calls and returns structured responses suitable for prompts. The architecture shows an LLM App (MCP Client) communicating with the Unleash MCP Server, which then talks to the Unleash API. The project is built with Node.js and TypeScript (Node.js v18+ and TypeScript v5+). It includes a modular structure under unleash-mcp-server/src with components for the main entry point, server, and configuration; transport adapters (HTTP/SSE, STDIO); Unleash API client wrappers; MCP resources for flags and projects; tools to fetch a flag or all projects; and prompts to query a single flag or multiple flags. Building, running, and inspecting commands are provided, enabling development, testing, and deployment of the MCP server in various environments.
