Mock MCP Server - AI-driven mock data orchestration with OpenAPI JSON Schema for testing
Implements a Daemon + Adapter architecture using IPC (Unix Domain Sockets/Named Pipes) that enables multiple MCP clients to connect simultaneously without port conflicts, while claim-based concurrency control prevents race conditions during batch mock processing. Schema-aware generation grounded in OpenAPI JSON Schema ensures AI-generated mocks strictly adhere to API contracts rather than hallucinating data, with batch collection and multi-run isolation supporting concurrent test processes across different MCP clients (Cursor, Claude Desktop, etc.).
