MCPJam Inspector is available as a hosted web app at app.mcpjam.com. Connect to your remote MCP servers, test tools, build apps, and use the LLM playground — all from your browser without installing anything.

Open MCPJam Inspector

Launch the hosted inspector in your browser

​
Why use the hosted app?

  • No installation — Open a browser and start testing.
  • Free LLM playground — Chat with your MCP server using our free models at no cost.
  • Always up to date — You’re always on the latest version without running npx @mcpjam/inspector@latest.
  • Shareable — Share server URLs with your team. Everyone can inspect the same server without local setup.

​
Share your MCP server

Send a link to your MCP server or app the same way you’d share a Google Doc. Anyone with a MCPJam account who opens it can immediately start chatting with the server in the playground — right in their browser. Try it yourself with the Excalidraw MCP server:

​
Quick start

  1. Go to app.mcpjam.com
  2. Click Add server and enter your MCP server’s URL (must be HTTPS)
  3. Choose your authentication method (None, Bearer Token, or OAuth 2.0)
  4. Start inspecting tools, resources, and prompts

​
What’s different

The following features are not available in the hosted app. They are available when running MCPJam locally via npx, Docker, or the desktop app.

​
HTTPS only

The hosted app requires all MCP server connections to use HTTPS. If your server only supports HTTP, use the local inspector instead.

​
No STDIO connections

STDIO servers are not available in the hosted version of MCPJam. Use SSE or Streamable HTTP transport instead.

​
No tunneling

Tunneling exposes a local MCP server over HTTPS for remote access. Since the hosted app connects to already-remote servers, tunneling is not applicable.

​
No skills

Skills are not yet available in the hosted app.

​
No tasks

Tasks are not yet available in the hosted app.
