Swagger MCP Bridge

If you're running a SpringDoc-powered Spring Boot API and want LLMs to call it directly, this starter autowires your OpenAPI spec into MCP tools with zero boilerplate. Beyond simple tool wrappers, it adds a gateway layer with meta-tools for API discovery, preflight validation, and multi-step workflow planning. You get JSONPath response shaping, execution guardrails for dangerous operations, and structured error codes. Works on Java 17+ with optional virtual threads on 21+. The example exposes a basic greeting controller, but the real use case is wrapping existing REST APIs so Claude can inspect capabilities, validate calls, and orchestrate sequences without hardcoding tool names.
