MCP OpenAPI Schema Explorer
An MCP (Model Context Protocol) server that provides token-efficient access to OpenAPI (v3.0) and Swagger (v2.0) specifications via MCP Resource Templates.
Project Goal
The primary goal of this project is to allow MCP clients (like Cline or Claude Desktop) to explore the structure and details of large OpenAPI specifications without needing to load the entire file into an LLM's context window. It achieves this by exposing parts of the specification through MCP Resource Templates, which provide parameterized access patterns for read-only data exploration.
This server supports loading specifications from both local file paths and remote HTTP/HTTPS URLs. Swagger v2.0 specifications are automatically converted to OpenAPI v3.0 upon loading.
Note: This server provides resource templates (not pre-enumerated resources). MCP clients access these templates through the
resources/templates/listprotocol method. For more information about resource templates, see the MCP Resource Templates documentation.
