MCP API Guardian

A local-first guardrail for AI coding agents that lints OpenAPI specs and detects breaking changes such as removed operations, new required parameters, or changed authentication. It runs entirely on the user's machine via the Model Context Protocol without requiring API keys or network access, helping developers catch contract errors before shipping.
