MCPJam inspector is the local testing tool for ChatGPT apps and MCP servers. Build your apps locally with MCPJam's widget emulator and test against any LLM in the playground. Inspect your MCP server’s tools, resources, prompts, and OAuth flows. No more ngrok or ChatGPT subscription needed.
MCPJam Inspector
Hey, it's Matt from MCPJam 👋.
We started MCPJam because the dev experience around building ChatGPT apps, MCP apps, and MCP servers wasn't great.
To develop a ChatGPT app, you had to get a ChatGPT pro subscription, ngrok you local MCP server, then connect it remotely on ChatGPT. There were also no good ways to test MCP servers and see how they behave in a real production environment.
That inspired us to build our open source inspector at MCPJam. We introduced:
Local ChatGPT and MCP apps emulator.
LLM playground to test your MCP server / apps in a real chat environment with any LLM
OAuth debugger to visualize MCP authorization at every step
and a bunch of other features that addresses the pains of MCP development.
If you're building a ChatGPT app, MCP app, or MCP server, I highly invite you to give us a try! Feel free to email me if you have any questions or feedback.

Congratulations on the launch! MCPJam was clutch when we were building and testing MCP apps at Noodle Seed.
