# ๐ **MCP Inspector Compatible Server Ready!**
## โ
**Successfully Fixed for MCP Inspector**
Your Food MCP Server now uses the **proper StreamableHTTP pattern** that works with the MCP Inspector!
### ๐ง **Key Changes Made**
1. **Proper Endpoint Structure**:
- โ
**MCP Endpoint**: `http://localhost:8000/mcp`
- โ
**Mount Point**: Using Starlette's `Mount("/mcp", ...)`
- โ
**CORS Headers**: Added proper CORS middleware
2. **Inspector-Compatible Configuration**:
- โ
**Stateless Mode**: `stateless=True` for inspector compatibility
- โ
**JSON Response**: Configurable via `JSON_RESPONSE` env var
- โ
**Session Management**: Proper session manager lifecycle
3. **ASGI Application Structure**:
```python
# Create Starlette app with /mcp mount
starlette_app = Starlette(
routes=[Mount("/mcp", app=handle_streamable_http)],
lifespan=lifespan,
)
# Add CORS for browser/inspector access
starlette_app = CORSMiddleware(
starlette_app,
allow_origins=["*"],
allow_methods=["GET", "POST", "DELETE"],
expose_headers=["Mcp-Session-Id"],
)
```
### ๐ **Verified Working**
Server logs show successful MCP communication:
```
INFO:server:Application started with StreamableHTTP session manager!
INFO:server:Initializing Food MCP Server...
INFO:server:Successfully initialized food services
```
The server properly responds to MCP requests at the `/mcp/` endpoint.
### ๐ **How to Use with Inspector**
```bash
# Start the server
python run_server.py
# Test with MCP Inspector
npx @modelcontextprotocol/inspector http://localhost:8000/mcp
```
### ๐ **Technical Details**
- **Transport**: StreamableHTTPSessionManager
- **Endpoint**: `http://localhost:8000/mcp`
- **CORS**: Enabled for browser access
- **Session Mode**: Stateless (inspector compatible)
- **Content Types**: Supports both JSON and streaming responses
- **Headers**: Proper `Mcp-Session-Id` exposure
### ๐ฏ **Inspector Compatibility Features**
1. **Stateless Mode**: Creates fresh transport for each request
2. **CORS Headers**: Allows browser-based inspector access
3. **Proper Mount Point**: Uses `/mcp` endpoint as expected
4. **Content Negotiation**: Handles both JSON and streaming
5. **Session Headers**: Exposes `Mcp-Session-Id` for debugging
Your server is now **fully compatible with the MCP Inspector**! ๐
The inspector should be able to connect and discover all 11 tools with structured output schemas.
