APIContractGuard — Live OpenAPI Contract Validation, Endpoint Probes, Drift Detection & Release Gate

Rank #161,927

smithery/tofan96you/apicontractguard-mcp

Safe live API contract validation engine for developers, engineering teams and AI agents. Parse OpenAPI JSON contracts; extract read-only endpoints, methods, parameters and expected responses; probe live GET, HEAD and OPTIONS endpoints for status, latency and content-type evidence; compare live behavior with supplied expectations; detect contract drift between documentation and implementation; generate prioritized API health reports; and run a release gate from contract, probe, schema and security review statuses. Mutating methods including POST, PUT, PATCH and DELETE are never called automatically. No API key required. Free tier: 10 requests/day. This is a release aid, not a security certification.
