# Docker Usage Guide for n8n-mcp
## Running in HTTP Mode
The n8n-mcp Docker container can be run in HTTP mode using several methods:
### Method 1: Using Environment Variables (Recommended)
```bash
docker run -d -p 3000:3000 \
--name n8n-mcp-server \
-e MCP_MODE=http \
-e AUTH_TOKEN=your-secure-token-here \
ghcr.io/czlonkowski/n8n-mcp:latest
```
### Method 2: Using docker-compose
```bash
# Create a .env file
cat > .env << EOF
MCP_MODE=http
AUTH_TOKEN=your-secure-token-here
PORT=3000
EOF
# Run with docker-compose
docker-compose up -d
```
### Method 3: Using a Configuration File
Create a `config.json` file:
```json
{
"MCP_MODE": "http",
"AUTH_TOKEN": "your-secure-token-here",
"PORT": "3000",
"LOG_LEVEL": "info"
}
```
Run with the config file:
```bash
docker run -d -p 3000:3000 \
--name n8n-mcp-server \
-v $(pwd)/config.json:/app/config.json:ro \
ghcr.io/czlonkowski/n8n-mcp:latest
```
### Method 4: Using the n8n-mcp serve Command
```bash
docker run -d -p 3000:3000 \
--name n8n-mcp-server \
-e AUTH_TOKEN=your-secure-token-here \
ghcr.io/czlonkowski/n8n-mcp:latest \
n8n-mcp serve
```
## Important Notes
1. **AUTH_TOKEN is required** for HTTP mode. Generate a secure token:
```bash
openssl rand -base64 32
```
2. **Environment variables take precedence** over config file values
3. **Default mode is stdio** if MCP_MODE is not specified
4. **Health check endpoint** is available at `http://localhost:3000/health`
## Troubleshooting
### Container exits immediately
- Check logs: `docker logs n8n-mcp-server`
- Ensure AUTH_TOKEN is set for HTTP mode
### "n8n-mcp: not found" error
- This has been fixed in the latest version
- Use the full command: `node /app/dist/mcp/index.js` as a workaround
### Config file not working
- Ensure the file is valid JSON
- Mount as read-only: `-v $(pwd)/config.json:/app/config.json:ro`
- Check that the config parser is present: `docker exec n8n-mcp-server ls -la /app/docker/`
