Agent VCR gives teams a way to test MCP: record client-server traffic into .vcr cassettes, replay it in tests and CI. No live servers, rate limits, or drift. Same format in Python and TypeScript so teams can share recordings. Built for compatibility gates, regression detection, and deterministic pipelines - the tool mature platform teams expect.
