A straightforward API testing toolkit that brings endpoint validation, response schema checks, and load testing into your Claude workflow. You get tools for validating REST endpoints, checking OpenAPI spec compliance, and running basic performance tests without leaving the conversation. Reach for this when you're building or debugging APIs and want to fire off quick validation checks or load tests without switching to Postman or curl scripts. The README mentions EU AI Act compliance features, though the core value is really about having API testing primitives available as MCP tools. Developed by MEOK AI Labs and distributed via PyPI.
