The server exposes contract testing, resiliency testing, and API mocking through four distinct tools—including a git-based backward compatibility checker (npm-only) that detects breaking changes by comparing OpenAPI specs across branches. It communicates via stdio transport with MCP-compatible agents (Claude Code, VSCode, Cursor, GitHub Copilot) and generates JUnit XML reports; the npm variant supports all features while Docker trades git access for containerized isolation.
