Description

This MCP server accepts OpenAPI (JSON or YAML) files and sends them to APIMatic’s API to produce validation summaries and reports. It is implemented in Node.js (v18+) and exposes a Model Context Protocol interface so tools like Claude Desktop can invoke it as a local MCP server. The server supports integration by supplying an APIMatic API key via environment variables and can be used to validate specs before deployment or during authoring.
