Blew MCP server allows AI tools and agents to scan for Bluetooth Low Energy (BLE) devices, connect to them, read the GATT tree and characteristics, read/write characteristics values and more. It's useful when developing BLE devices or doing security research/reverse engineering. Main features: * Scan for BLE devices with filtering by name, service UUID, RSSI, manufacturer * Connect to devices and walk the full GATT tree (services, characteristics, descriptors) * Read and write characteristic values with automatic format detection * Subscribe to notifications and collect batches * Look up Bluetooth SIG specs for any characteristic UUID * Spin up a BLE peripheral and advertise custom services from your Mac * Clone a real device's GATT structure and impersonate it * Push value updates and notify connected subscribers
