Implementation Reference

• src/unifi_mcp/server.py:186-194 (handler)

  The execution logic for the block_client tool within the unified call_tool handler.
  case "block_client": mac = arguments.get("mac", "") await client.block_client(mac) return [ TextContent( type="text", text=f"Client {mac} has been blocked from the network.", ) ]
• src/unifi_mcp/server.py:60-73 (schema)

  Input schema and metadata for the block_client tool, defined in list_tools().
  Tool( name="block_client", description="Block a client from accessing the network", inputSchema={ "type": "object", "properties": { "mac": { "type": "string", "description": "MAC address of the client to block", } }, "required": ["mac"], }, ),
• src/unifi_mcp/server.py:16-149 (registration)

  Decorators registering the tool list and call handlers for all tools including block_client.
