# MCP Inspector
|
|
|
|
The MCP inspector is a developer tool for testing and debugging MCP servers.
|
|
|
|
|
|
|
|
## Running the Inspector
|
|
|
|
### From an MCP server repository
|
|
|
|
To inspect an MCP server implementation, there's no need to clone this repo. Instead, use `npx`. For example, if your server is built at `build/index.js`:
|
|
|
|
```bash
|
|
npx @modelcontextprotocol/inspector build/index.js
|
|
```
|
|
|
|
You can also pass arguments along which will get passed as arguments to your MCP server:
|
|
|
|
```
|
|
npx @modelcontextprotocol/inspector build/index.js arg1 arg2 ...
|
|
```
|
|
|
|
The inspector runs both a client UI (default port 5173) and an MCP proxy server (default port 3000). Open the client UI in your browser to use the inspector. You can customize the ports if needed:
|
|
|
|
```bash
|
|
CLIENT_PORT=8080 SERVER_PORT=9000 npx @modelcontextprotocol/inspector build/index.js
|
|
```
|
|
|
|
### From this repository
|
|
|
|
If you're working on the inspector itself:
|
|
|
|
Development mode:
|
|
|
|
```bash
|
|
npm run dev
|
|
```
|
|
|
|
Production mode:
|
|
|
|
```bash
|
|
npm run build
|
|
npm start
|
|
```
