🚀 HTTP-4-MCP Middleware Server

What is HTTP-4-MCP Middleware Server?

HTTP-4-MCP Middleware Server is a middleware tool that transforms regular HTTP interfaces into MCP (Model Context Protocol) interfaces with simple JSON configuration. It allows any HTTP API to instantly become an MCP tool. It is designed for developers who want to expose existing HTTP APIs as MCP resources.

How to use HTTP-4-MCP Middleware Server?

Clone the repository, install dependencies (recommended using uv), then start the main server with uv run run.py. Optionally start the visual configuration UI with uv run run_config_ui.py. Configure APIs either through the drag‑and‑drop interface at http://localhost:8002 or by editing a JSON configuration file. Connect to the MCP server via the SSE endpoint http://localhost:8000/mcp/sse.
