UniFi MCP Server

Instructions

Implementation Reference

• src/unifi_mcp/server.py:206-214 (handler)

  MCP tool handler for disconnect_client: extracts MAC from arguments, calls UniFiClient.disconnect_client(mac), and returns success message.
  case "disconnect_client": mac = arguments.get("mac", "") await client.disconnect_client(mac) return [ TextContent( type="text", text=f"Client {mac} has been disconnected.", ) ]
• src/unifi_mcp/server.py:88-101 (schema)

  Input schema definition for the disconnect_client tool, requiring a 'mac' string parameter.
  Tool( name="disconnect_client", description="Force disconnect a client from the network", inputSchema={ "type": "object", "properties": { "mac": { "type": "string", "description": "MAC address of the client to disconnect", } }, "required": ["mac"], }, ),
• src/unifi_mcp/server.py:16-146 (registration)

  Registers the disconnect_client tool via @server.list_tools() decorator by including it in the returned list of available tools.
  @server.list_tools() async def list_tools() -> list[Tool]: """List all available UniFi MCP tools.""" return [ # Device tools Tool( name="get_devices", description="Get all UniFi network devices (access points, switches, gateways)", inputSchema={ "type": "object", "properties": {}, "required": [], }, ), Tool( name="restart_device", description="Restart a UniFi network device by its MAC address", inputSchema={ "type": "object", "properties": { "mac": { "type": "string", "description": "MAC address of the device to restart (e.g., '00:11:22:33:44:55')", } }, "required": ["mac"], }, ), # Client tools Tool( name="get_clients", description="Get all currently connected clients on the UniFi network", inputSchema={ "type": "object", "properties": { "include_offline": { "type": "boolean", "description": "Include offline/historical clients", "default": False, } }, "required": [], }, ), 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"], }, ), Tool( name="unblock_client", description="Unblock a previously blocked client", inputSchema={ "type": "object", "properties": { "mac": { "type": "string", "description": "MAC address of the client to unblock", } }, "required": ["mac"], }, ), Tool( name="disconnect_client", description="Force disconnect a client from the network", inputSchema={ "type": "object", "properties": { "mac": { "type": "string", "description": "MAC address of the client to disconnect", } }, "required": ["mac"], }, ), # Site tools Tool( name="get_sites", description="Get all UniFi sites configured on the controller", inputSchema={ "type": "object", "properties": {}, "required": [], }, ), Tool( name="get_site_health", description="Get health status for the current site", inputSchema={ "type": "object", "properties": {}, "required": [], }, ), Tool( name="get_networks", description="Get all network configurations for the current site", inputSchema={ "type": "object", "properties": {}, "required": [], }, ), # Activity tools Tool( name="get_device_activity", description="Get activity for a specific device including connected clients and their traffic", inputSchema={ "type": "object", "properties": { "mac": { "type": "string", "description": "MAC address of the device (AP or switch)", } }, "required": ["mac"], }, ), ]
• src/unifi_mcp/unifi_client.py:266-280 (helper)

  Low-level implementation that sends UniFi API request to kick (disconnect) the client by MAC address.
  async def disconnect_client(self, mac: str) -> bool: """Force disconnect a client. Args: mac: Client MAC address. Returns: True if disconnect command was sent successfully. """ await self._request( "POST", "/api/s/{site}/cmd/stamgr", json={"cmd": "kick-sta", "mac": mac.lower()}, ) return True
