Test, Debug, and Evaluate MCP servers, ChatGPT apps, and MCP Apps (ext-apps)

README

MCPJam Inspector V1 logo

www.mcpjam.com

npm versionLicense: Apache 2.0DiscordMCPJam is the development platform for MCP servers, MCP apps, and ChatGPT apps.

  • Debug: Inspect every JSON-RPC message and OAuth exchange across host configurations with full traces.
  • Chat: Talk to any LLM against your server with full trace visibility into tool calls and context across agent, host app, your server.
  • Inspect: Explore your serverโ€™s tools, resources, and prompts in one place.
  • Evaluate: Run evals across multiple LLMs and track accuracy over time so you catch regressions early.
  • CLI: Probe servers, run doctor checks, exercise OAuth flows, and list tools/resources/prompts straight from your terminal.
  • SDK: Programmatically drive inspections, snapshot server capabilities, and assert on tool/resource shapes from your own tests.
  • CI/CD: Wire the CLI and SDK into GitHub Actions (or any pipeline) to run e2e tests, evals, OAuth checks, and spec conformance on every PR.

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

๐Ÿš€ Quick Start

Open the hosted web app. No install needed.

๐Ÿ‘‰ app.mcpjam.com

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

npx @mcpjam/inspector@latest

Installation Guides

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.

Requirements

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

Hosted Web App

Open app.mcpjam.com in your browser. No install required. Always on the latest version, and you can share MCP server links with teammates the same way you'd share a Google Doc.

  • HTTPS MCP server URLs only (for HTTP or local STDIO servers, use Desktop or Terminal).
  • No STDIO, tunneling, skills, or tasks. Those require the local inspector.

See Hosted App docs for details.

Desktop App

Download the installer for your OS. Supports HTTP/S and local STDIO servers. No Node.js required.

Terminal

Run the inspector via npx (supports HTTP/S and local STDIO):

npx @mcpjam/inspector@latest

After it starts, open the printed localhost URL in your browser.

Docker

Run MCPJam Inspector using Docker, bound to localhost for security:

docker run -p 127.0.0.1:6274:6274 mcpjam/mcp-inspector

The app is available at http://127.0.0.1:6274. Always use -p 127.0.0.1:6274:6274 (not -p 6274:6274) to keep the inspector local-only. On macOS/Windows, connect to host MCP servers via http://host.docker.internal:PORT instead of 127.0.0.1.
