OASTools

概要

OASTools is a comprehensive, self-contained toolkit for working with OpenAPI Specification (OAS) documents, built in Go with minimal dependencies. It offers a full lifecycle suite for OpenAPI specs, including parsing, validating, fixing, converting between versions (2.0-3.2), and performing multi-spec operations like diffing, joining, and applying overlays. Beyond spec management, it can generate client and server code, query specs, and includes an HTTP validator. The tool is highly performant, extensively tested, and includes an AI-ready Model Context Protocol (MCP) server for integration with LLM agents.
