About

Emcee is a CLI tool that creates Model Context Protocol servers from OpenAPI specifications, enabling AI assistants to interact with REST APIs through JSON-RPC. Developed by Loopwork AI, it processes an OpenAPI spec (from a file, URL, or stdin) and automatically generates tools that map to API endpoints, handling authentication, parameter validation, and response formatting. The tool supports various authentication methods including Bearer tokens and Basic auth, with secure 1Password integration for credential management. Emcee is particularly useful for quickly exposing existing APIs to Claude Desktop and other MCP-compatible assistants without writing custom integration code.
