OpenAPI Schema

The OpenAPI Schema MCP server exposes OpenAPI specification information to Large Language Models through a set of specialized tools. Developed by Hannes Junnila, it loads any OpenAPI schema file (JSON or YAML) and provides tools for exploring API paths, operations, parameters, schemas, and security definitions. The server converts complex OpenAPI structures into YAML format for better LLM comprehension and includes features like endpoint listing, schema searching, and example retrieval. It's particularly valuable for workflows requiring API exploration and understanding within AI assistant conversations, eliminating the need to manually parse OpenAPI documentation.
