### Integrating with AI Assistants ### Integrating with AI Assistants
To use this MCP server with AI assistants, you need to register it with your AI assistant platform. The exact method depends on the platform you're using. After building the server (`npm run build`), you need to configure your AI assistant (like VS Code with the Claude extension or the Claude Desktop app) to run it. This typically involves editing a JSON configuration file.
For example, with the MCP installer: **Example Configuration (e.g., in VS Code `settings.json` or Claude Desktop `claude_desktop_config.json`):**
```bash ```json
npx @anaisbetts/mcp-installer {
"mcpServers": {
// Give your server a unique name
"n8n-local": {
// Use 'node' to execute the built JavaScript file
"command": "node",
// Provide the *absolute path* to the built index.js file
"args": [
"/path/to/your/cloned/n8n-mcp-server/build/index.js"
// On Windows, use double backslashes:
// "C:\\path\\to\\your\\cloned\\n8n-mcp-server\\build\\index.js"
],
// Environment variables needed by the server
"env": {
"N8N_API_URL": "http://your-n8n-instance:5678/api/v1", // Replace with your n8n URL
"N8N_API_KEY": "YOUR_N8N_API_KEY", // Replace with your key
// Add webhook credentials only if you plan to use webhook tools
// "N8N_WEBHOOK_USERNAME": "your_webhook_user",
// "N8N_WEBHOOK_PASSWORD": "your_webhook_password"
},
// Ensure the server is enabled
"disabled": false,
// Default autoApprove settings
"autoApprove": []
}
// ... other servers might be configured here
}
}
``` ```
Then register the server: **Key Points:**
``` * Replace `/path/to/your/cloned/n8n-mcp-server/` with the actual absolute path where you cloned and built the repository.
install_local_mcp_server path/to/n8n-mcp-server * Use the correct path separator for your operating system (forward slashes `/` for macOS/Linux, double backslashes `\\` for Windows).
``` * Ensure you provide the correct `N8N_API_URL` (including `/api/v1`) and `N8N_API_KEY`.
* The server needs to be built (`npm run build`) before the assistant can run the `build/index.js` file.
