# Running MCP Gateway with Open-UI
|
||||
|
||||
You now have OpenAI-compatible endpoints for your MCP Gateway! This allows Open-UI to use all your MCP tools.
|
||||
|
||||
## ✅ What's Been Done
|
||||
|
||||
1. ✅ Created `openai_routes.py` - Handles OpenAI-compatible API requests
|
||||
2. ✅ Updated `gateway_proxy.py` - Added `/v1/models` and `/v1/chat/completions` endpoints
|
||||
3. ✅ Configuration ready - Just need to restart the gateway
|
||||
|
||||
## 🚀 Next Steps
|
||||
|
||||
### Step 1: Restart Your Gateway
|
||||
|
||||
```bash
|
||||
cd /sessions/beautiful-serene-gauss/mnt/MCP\ Servers/mcp-gateway/
|
||||
docker compose restart mcp-gateway
|
||||
```
|
||||
|
||||
Check the logs to verify the endpoints are registered:
|
||||
|
||||
```bash
|
||||
docker compose logs mcp-gateway | grep -i "openai\|v1"
|
||||
```
|
||||
|
||||
You should see: `OpenAI-compatible endpoints registered at /v1/*`
|
||||
|
||||
### Step 2: Test the New Endpoints
|
||||
|
||||
**Test `/v1/models`:**
|
||||
```bash
|
||||
curl -H "Authorization: Bearer rIoRseJSR9rqwl5bp4CEOyOUKdymaoJnAsT-y752BDi2qD9jJYbgd8sWkiQIGMtz" \
|
||||
https://mcp.wilddragon.net/v1/models
|
||||
```
|
||||
|
||||
Expected response:
|
||||
```json
|
||||
{
|
||||
"object": "list",
|
||||
"data": [
|
||||
{
|
||||
"id": "mcp-gateway",
|
||||
"object": "model",
|
||||
"owned_by": "mcp-gateway"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
### Step 3: Configure Open-UI
|
||||
|
||||
1. **Open Open-UI**: http://10.0.0.25:3009/
|
||||
2. **Go to**: Admin → Settings → Connections
|
||||
3. **Scroll to**: "Direct Connections"
|
||||
4. **Enable**: Toggle "Direct Connections" ON
|
||||
5. **Add Connection**:
|
||||
- **API Base URL**: `https://mcp.wilddragon.net/v1`
|
||||
- **API Key**: `rIoRseJSR9rqwl5bp4CEOyOUKdymaoJnAsT-y752BDi2qD9jJYbgd8sWkiQIGMtz`
|
||||
6. **Click**: Save
|
||||
|
||||
### Step 4: Use in Open-UI
|
||||
|
||||
1. **Create a new chat**
|
||||
2. **Model selection**: Choose `mcp-gateway`
|
||||
3. **Start chatting** - The gateway will show available tools
|
||||
|
||||
## 🔑 Your Bearer Token
|
||||
|
||||
```
|
||||
rIoRseJSR9rqwl5bp4CEOyOUKdymaoJnAsT-y752BDi2qD9jJYbgd8sWkiQIGMtz
|
||||
```
|
||||
|
||||
Save this somewhere safe. It's what authenticates requests from Open-UI to your gateway.
|
||||
|
||||
## 🛠️ Running Both Systems
|
||||
|
||||
Your setup now runs:
|
||||
|
||||
```
|
||||
┌─────────────────────────────────────────────┐
|
||||
│ Your Workstation │
|
||||
├─────────────────────────────────────────────┤
|
||||
│ Claude.ai ──────────────┐ │
|
||||
│ ▼ │
|
||||
│ MCP Gateway │
|
||||
│ (Port 4444) │
|
||||
│ ▲ │
|
||||
│ Open-UI ────────────────┘ │
|
||||
│ (Port 3009) │
|
||||
└─────────────────────────────────────────────┘
|
||||
│
|
||||
│ ERPNext, TrueNAS, Home Assistant, Wave
|
||||
▼
|
||||
(External services)
|
||||
```
|
||||
|
||||
**Both Claude and Open-UI** can now:
|
||||
- ✅ List all available MCP tools
|
||||
- ✅ Call Wave Finance tools (invoices, customers, etc.)
|
||||
- ✅ Execute TrueNAS commands (storage, snapshots, etc.)
|
||||
- ✅ Control Home Assistant (lights, climate, etc.)
|
||||
- ✅ Query ERPNext data
|
||||
|
||||
## 📝 API Endpoints Now Available
|
||||
|
||||
| Endpoint | Method | Purpose |
|
||||
|----------|--------|---------|
|
||||
| `/v1/models` | GET | List available models (returns `mcp-gateway`) |
|
||||
| `/v1/chat/completions` | POST | OpenAI-compatible chat endpoint |
|
||||
| `/mcp` | POST | Raw MCP protocol (for Claude) |
|
||||
| `/health` | GET | Health check |
|
||||
| `/status` | GET | Gateway status |
|
||||
|
||||
## 🔧 Advanced Configuration
|
||||
|
||||
### Using a Different Bearer Token
|
||||
|
||||
If you want to use a different token:
|
||||
|
||||
1. **Update `.env`** (if you want to persist it):
|
||||
```bash
|
||||
GATEWAY_API_TOKEN=your_new_token_here
|
||||
```
|
||||
|
||||
2. **Restart gateway**:
|
||||
```bash
|
||||
docker compose restart mcp-gateway
|
||||
```
|
||||
|
||||
### Enabling Tool Execution
|
||||
|
||||
Currently, the gateway shows available tools. To actually execute them:
|
||||
|
||||
1. Edit `gateway-proxy/openai_routes.py`
|
||||
2. Uncomment the `_call_mcp_tool()` function calls
|
||||
3. Add logic to process tool calls in the response
|
||||
|
||||
### Custom System Prompt
|
||||
|
||||
Edit `openai_routes.py` function `_get_mcp_tools()` to add a custom system prompt that guides the LLM on how to use tools.
|
||||
|
||||
## ⚠️ Troubleshooting
|
||||
|
||||
### "Connection refused" error
|
||||
- **Check**: Is the gateway running? `docker compose ps`
|
||||
- **Restart**: `docker compose restart mcp-gateway`
|
||||
- **Check logs**: `docker compose logs mcp-gateway`
|
||||
|
||||
### "Unauthorized" error
|
||||
- **Check**: Bearer token is correct
|
||||
- **Check**: Header format: `Authorization: Bearer YOUR_TOKEN`
|
||||
|
||||
### No tools showing
|
||||
- **Check**: Are MCP backends initialized? `docker compose logs mcp-erpnext`
|
||||
- **Check**: Is `/mcp` endpoint working? Test with Claude.ai first
|
||||
|
||||
## ✨ Next: Production Hardening
|
||||
|
||||
When ready, consider:
|
||||
|
||||
1. **HTTPS certificates** - Use proper SSL/TLS
|
||||
2. **Rate limiting** - Prevent API abuse
|
||||
3. **Logging** - Monitor all requests
|
||||
4. **Metrics** - Track usage patterns
|
||||
5. **Tool execution** - Actually execute MCP tools, not just list them
|
||||
|
||||
