Eufy RoboVac MCP Server

Instructions

Implementation Reference

• src/server.ts:438-491 (handler)

  Handler logic for the robovac_connect tool. Attempts connection with provided IP or falls back to auto-discovery and default IP, using the initializeRoboVac helper.
  case "robovac_connect": // Auto-discover best IP if not provided or if connection fails let connectTargetIP = args?.ip as string | undefined; let connectSuccess = false; if (connectTargetIP) { connectSuccess = await this.initializeRoboVac( args?.deviceId as string, args?.localKey as string, connectTargetIP ); } if (!connectSuccess) { console.error( "[DEBUG] Manual connection failed or no IP provided, trying auto-discovery..." ); const discoveredIP = await this.discoverBestRoboVacIP(); if (discoveredIP) { connectTargetIP = discoveredIP; connectSuccess = await this.initializeRoboVac( args?.deviceId as string, args?.localKey as string, connectTargetIP ); } } // Fallback to default IP if still not successful if (!connectSuccess && !connectTargetIP) { connectTargetIP = "192.168.1.100"; connectSuccess = await this.initializeRoboVac( args?.deviceId as string, args?.localKey as string, connectTargetIP ); } return { content: [ { type: "text", text: connectSuccess ? `RoboVac connected successfully at ${connectTargetIP}!` : `Failed to connect to RoboVac. ${ connectTargetIP ? `Tried ${connectTargetIP} but connection failed.` : "" } Check your device ID, local key, and network connection.`, }, ], isError: !connectSuccess, };
• src/server.ts:321-343 (schema)

  Input schema and description for the robovac_connect tool, defined in the listTools response.
  name: "robovac_connect", description: "Connect to your RoboVac using device credentials (manual setup)", inputSchema: { type: "object", properties: { deviceId: { type: "string", description: "The device ID of your Eufy RoboVac", }, localKey: { type: "string", description: "The local key for your Eufy RoboVac", }, ip: { type: "string", description: "The IP address of your Eufy RoboVac (optional, defaults to 192.168.1.100)", }, }, required: ["deviceId", "localKey"], }, },
• src/server.ts:43-59 (helper)

  Helper method that creates a new RoboVac instance with the given credentials and attempts to connect. Returns success boolean.
  private async initializeRoboVac( deviceId: string, localKey: string, ip?: string ): Promise<boolean> { try { this.robovac = new RoboVac({ deviceId: deviceId, localKey: localKey, ip: ip || "192.168.1.100", }); await this.robovac.connect(); return true; } catch (error) { console.error("Failed to initialize RoboVac:", error); return false; }
• src/server.ts:70-112 (helper)

  Helper method for auto-discovering the best IP for a RoboVac device on the network, used as fallback in the connect handler.
  private async discoverBestRoboVacIP(): Promise<string | null> { try { console.error("[DEBUG] Auto-discovering RoboVac devices..."); const devices = await this.networkDiscovery.discoverDevices(); if (devices.length === 0) { console.error("[DEBUG] No devices found during auto-discovery"); return null; } // Filter for likely RoboVac devices const likelyRoboVacs = devices.filter((device) => device.isLikelyRoboVac); if (likelyRoboVacs.length > 0) { const bestDevice = likelyRoboVacs[0]; // Take the first likely device console.error( `[DEBUG] Found likely RoboVac at ${bestDevice.ip} (MAC: ${bestDevice.mac}, Vendor: ${bestDevice.vendor})` ); return bestDevice.ip; } // If no likely RoboVacs, try devices with port 6668 open const devicesWithPort6668 = devices.filter((device) => device.ports.includes(6668) ); if (devicesWithPort6668.length > 0) { const potentialDevice = devicesWithPort6668[0]; console.error( `[DEBUG] Found potential RoboVac at ${potentialDevice.ip} with port 6668 open` ); return potentialDevice.ip; } console.error("[DEBUG] No suitable RoboVac candidates found"); return null; } catch (error) { console.error( `[DEBUG] Auto-discovery failed: ${(error as Error).message}` ); return null; } }
