Run sample
This sample starts an MCP Server with a middleware that checks for a valid Authorization header.
Install dependencies
pip install "mcp[cli]"
Start server
python server.py
start the client in another terminal
python client.py
You should see a result similar to:
2025-09-30 13:25:54 - mcp_client - INFO - Tool result: meta=None content=[TextContent(type='text', text='{\n "current_time": "2025-09-30T13:25:54.311900",\n "timezone": "UTC",\n "timestamp": 1759238754.3119,\n "formatted": "2025-09-30 13:25:54"\n}', annotations=None, meta=None)] structuredContent={'current_time': '2025-09-30T13:25:54.311900', 'timezone': 'UTC', 'timestamp': 1759238754.3119, 'formatted': '2025-09-30 13:25:54'} isError=False
this means the credential being sent through is being allowed.
Try changing the credential in client.py to "secret-token2", then you should see this text as part of the response:
2025-09-30 13:27:44 - httpx - INFO - HTTP Request: POST http://localhost:8000/mcp "HTTP/1.1 403 Forbidden"
this means you were authenticated (you had a credential), but it was invalid.
