🎯 Why?

MCP adoption is exploding, but connecting a random REST endpoint still means writing a server, schema, and request glue. curl is the universal language for HTTP requests, yet there is no tiny zero-config adapter that converts a curl command into an MCP tool. curl2mcp fills that gap by parsing {placeholders} and serving the request over stdio.

Target audience: AI tool builders, Claude/Cursor users, platform engineers, and agent developers who need to expose HTTP APIs to MCP clients without writing boilerplate.

✨ Features

• ✨ Parse a curl command into an MCP tool schema with placeholder extraction
• ✨ Run the templated request directly from the CLI for quick testing
• ✨ Serve the tool over MCP stdio for Claude, Cursor, or any MCP client
• ✨ Zero external runtime dependencies beyond the Python standard library
