What it is
MCPJam Inspector is a testing and evaluation platform to chat, inspect, and debug MCP servers, MCP apps, and ChatGPT apps.
How it works
The project offers multiple interaction modes:
- Hosted web app (no install) and desktop app for HTTP/S and local STDIO servers.
- Terminal usage via npx to run the inspector locally.
- CLI, SDK, and CI/CD features integrate checks, evals, and conformance into workflows.
- App Builder, Chat, OAuth Debugger, MCP Server Debugging, Skills, Workspaces, Evals, and CI/CD capabilities are described as core features in the README.
