swag2mcp is a local-first bridge between OpenAPI/Swagger/Postman API specifications and LLM agents via the Model Context Protocol (MCP).
Not every API speaks MCP — private endpoints, internal services, legacy systems, and third-party APIs rarely do. swag2mcp wraps any REST API in an MCP interface, giving LLM agents instant access to your entire API surface without modifying a single line of server code. Through live API calls, the LLM gains real-world knowledge to make informed decisions, automate workflows, and act on your data — not just guess.
- 16 MCP tools for discovering, inspecting, and invoking APIs
- Interactive TUI explorer with full-text search
- Zero integration code — just point to your specs and go
