MCPJam - The testing & evaluations platform for MCP servers

Run User Testing, Swarms, Evals, and CI/CD gates on your MCP server to see if users actually succeed in ChatGPT, Claude, and Copilot. Test local servers via desktop app, CLI, or SDK.

Looks great! Particularly excited for evals that can run for different clients. I’m often dealing with customers using gemini, chatgpt, claude etc asking why their prompts aren’t doing what they expect when communicating with our MCP server, and evals will help bridge that gap

 Cross-client diffs are probably the biggest complaints we get, to just understand client diffs is a start, exciting to launch this platform to build a durable solution here though!
