MCPJam is the development platform for MCP servers, MCP apps, and ChatGPT apps.

No more ngrok or ChatGPT/Claude subscription needed. MCPJam is the fastest way to iterate on any MCP project.

Or run MCPJam locally for HTTP/S and local STDIO servers:

MCPJam Inspector runs three ways: a hosted web app, a desktop app for Mac and Windows, or via your terminal. The web app is HTTPS-only and has no install. Terminal and Desktop support HTTP/S and local STDIO servers.

Node.js 20+ is only required for the terminal install (npx). The hosted web app and desktop apps have no local runtime requirements.
