Hippycampus (OpenAPI Tools)

Converts OpenAPI specifications into LangChain tools, enabling AI assistants to interact with existing REST APIs without custom implementation

Hippycampus is a LangChain-based MCP server that dynamically loads OpenAPI specifications to expose external APIs as tools for AI agents. Developed by Ray Cromwell, it bridges the gap between LangChain's structured agent capabilities and the MCP protocol, enabling seamless integration with Langflow for visual workflow creation. The server supports both CLI and SSE transport modes, automatically converts OpenAPI endpoints into structured tools, and handles authentication tokens for secure API access. Particularly useful for developers who want to quickly enable AI assistants to interact with existing REST APIs without writing custom tool implementations.
