# Claude Desktop Configuration for n8n-MCP
|
|
|
|
## Setup Instructions
|
|
|
|
1. **Build the project first:**
|
|
```bash
|
|
cd /Users/romualdczlonkowski/Pliki/n8n-mcp/n8n-mcp
|
|
npm run build
|
|
npm run rebuild
|
|
```
|
|
|
|
2. **Locate your Claude Desktop config file:**
|
|
- macOS: `~/Library/Application Support/Claude/claude_desktop_config.json`
|
|
- Windows: `%APPDATA%\Claude\claude_desktop_config.json`
|
|
- Linux: `~/.config/Claude/claude_desktop_config.json`
|
|
|
|
3. **Add the n8n-documentation server to your config:**
|
|
```json
|
|
{
|
|
"mcpServers": {
|
|
"n8n-documentation": {
|
|
"command": "node",
|
|
"args": [
|
|
"/Users/johndoe/projects/n8n-mcp/dist/mcp/index.js"
|
|
],
|
|
"env": {
|
|
"NODE_ENV": "production"
|
|
}
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
**Note**: Update the path in `args` to match your actual installation directory.
|
|
|
|
4. **Restart Claude Desktop** to load the new configuration.
|
|
|
|
## Available Tools
|
|
|
|
Once configured, you'll have access to these tools in Claude:
|
|
|
|
- **`list_nodes`** - List and filter n8n nodes
|
|
```
|
|
list_nodes({ package: "n8n-nodes-base", limit: 10 })
|
|
```
|
|
|
|
- **`get_node_info`** - Get detailed information about a specific node
|
|
```
|
|
get_node_info({ nodeType: "httpRequest" })
|
|
```
|
|
|
|
- **`search_nodes`** - Search across all node documentation
|
|
```
|
|
search_nodes({ query: "webhook", limit: 20 })
|
|
```
|
|
|
|
- **`list_ai_tools`** - List nodes that can be used as AI Agent tools
|
|
```
|
|
list_ai_tools({})
|
|
```
|
|
|
|
- **`get_node_documentation`** - Get full documentation for a node
|
|
```
|
|
get_node_documentation({ nodeType: "slack" })
|
|
```
|
|
|
|
- **`get_database_statistics`** - Get statistics about the node database
|
|
```
|
|
get_database_statistics({})
|
|
```
|
|
|
|
## Troubleshooting
|
|
|
|
1. **If the server doesn't appear in Claude:**
|
|
- Check that the path in `args` is absolute and correct
|
|
- Ensure you've run `npm run build` and `npm run rebuild`
|
|
- Check `~/.n8n-mcp/logs/` for error logs
|
|
|
|
2. **If tools return errors:**
|
|
- Ensure the database exists: `data/nodes.db`
|
|
- Run `npm run validate` to check the database
|
|
- Rebuild if necessary: `npm run rebuild`
|
|
|
|
3. **For development/testing:**
|
|
You can also run with more verbose logging:
|
|
```json
|
|
{
|
|
"mcpServers": {
|
|
"n8n-documentation": {
|
|
"command": "node",
|
|
"args": [
|
|
"/path/to/your/n8n-mcp/dist/mcp/index.js"
|
|
],
|
|
"env": {
|
|
"NODE_ENV": "development",
|
|
"LOG_LEVEL": "debug"
|
|
}
|
|
}
|
|
}
|
|
}
|
|
``` |
