Hosted App

Use MCPJam Inspector in the browser — no installation required

MCPJam Inspector is available as a hosted web app at app.mcpjam.com. Build, test, debug, and evaluate MCP servers and apps with frontier models — all from the web.

Open MCPJam Inspector

Launch the hosted inspector in your browser

Why use the hosted app?

• No installation — Open a browser and start testing.
• 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 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 a Streamable HTTP endpoint instead, or switch to the local inspector.

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 live on your filesystem and can only be discovered and run from the local inspector or desktop app.

No tasks

Tasks are not yet available in the hosted app.
