Description

MCP-Link is a server implementation that converts OpenAPI specifications into MCP-compatible endpoints, enabling AI assistants to interact with any API described in OpenAPI format. Written in Go, it features a simple HTTP server that parses OpenAPI YAML/JSON files, transforms API endpoints into MCP tools, and handles authentication through header forwarding. The implementation supports path filtering, parameter mapping, and various authentication methods, making it ideal for developers who want to quickly expose existing APIs to AI assistants without writing custom MCP adapters for each service.
