MCPJam launched its platform on Product Hunt on September 17 at #7 with 150 upvotes, offering interactive testing of tools, prompts, resources and authorization across 16 client configurations and 170+ models, plus evals that gate regressions in CI. The Inspector, CLI, SDK, local evals and conformance checks are open source and free, with the hosted platform as the paid layer, and it runs as a web app, a Mac/Windows desktop app, or from the terminal. The company's own framing is that shipping ChatGPT apps and MCP servers previously required a ChatGPT Pro subscription and ngrok tunneling with no production-like testing path, which is the gap that made an MCP-specific QA vendor possible at all.
