How to Set Up and Use Inspector

MCP Inspector is the official developer tool for testing and debugging MCP servers, built and maintained by the Model Context Protocol team. It provides a React-based web UI and a Node.js proxy that can connect to any MCP server over stdio, SSE, or Streamable HTTP transports, letting you interactively list and call tools, read resources, test prompts, and inspect the full request/response cycle. Every MCP server developer should use it during development to verify their server behaves correctly before connecting it to an AI client.

Prerequisites

  • Node.js 18+ and npx installed
  • A running or locally built MCP server to test
  • A modern web browser (Chrome, Firefox, Safari, or Edge)
  • Docker (optional, for the containerized deployment)
1

Launch the Inspector UI

Run the Inspector with npx โ€” no installation required. It starts a local web server and opens the UI in your browser automatically.

npx @modelcontextprotocol/inspector
2

Launch with a specific MCP server

Pass your MCP server's start command directly to the Inspector. It will start the server as a subprocess and connect to it over stdio.

npx @modelcontextprotocol/inspector node build/index.js
3

Pass environment variables to the server

Use the -e flag to inject environment variables into the MCP server process being tested.

npx @modelcontextprotocol/inspector -e API_KEY=your-key node build/index.js
4

Use CLI mode for scripting and automation

The --cli flag runs the Inspector in headless mode, useful for CI pipelines, scripted tests, or integration with coding assistants.

npx @modelcontextprotocol/inspector --cli node build/index.js
5

Run with Docker for isolated testing

Use the official Docker image to run the Inspector in a sandboxed environment without installing Node.js locally.

docker run --rm -p 127.0.0.1:6274:6274 -p 127.0.0.1:6277:6277 \
  -e HOST=0.0.0.0 -e MCP_AUTO_OPEN_ENABLED=false \
  ghcr.io/modelcontextprotocol/inspector:latest
6

Explore tools, resources, and prompts in the UI

In the browser UI, use the Tools tab to list and call your server's tools, the Resources tab to browse and read resources, and the Prompts tab to test prompt templates โ€” all with full request/response visibility.

Inspector Examples

Client configuration

The Inspector itself is a development tool, not a server you add to an AI client. This shows how to add it to Claude Desktop for debugging MCP servers from within Claude.

{
  "mcpServers": {
    "inspector": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/inspector"]
    }
  }
}

Prompts to try

The Inspector is a web UI tool โ€” use these commands in your terminal to launch it against real MCP servers for debugging.

- "npx @modelcontextprotocol/inspector node build/index.js"
- "npx @modelcontextprotocol/inspector python server.py"
- "npx @modelcontextprotocol/inspector --cli node build/index.js (for headless/CI mode)"
- "Open http://localhost:6274 in your browser to access the Inspector UI"

Troubleshooting Inspector

Browser does not open automatically after launch

Navigate manually to http://localhost:6274 in your browser. If the port is in use, set a custom port with the CLIENT_PORT environment variable: CLIENT_PORT=6280 npx @modelcontextprotocol/inspector

Server connection fails or tools list is empty

Verify the MCP server starts without errors by running it standalone first (node build/index.js). Check that the server implements the MCP protocol correctly and that all required environment variables are passed via the -e flag.

DANGEROUSLY_OMIT_AUTH warning appears

This warning appears when auth is disabled for local testing. Never set DANGEROUSLY_OMIT_AUTH=true in production or shared environments. For team use, set MCP_PROXY_AUTH_TOKEN to a shared secret instead.
