Description

BLEMCPServer provides a Model Context Protocol server over Bluetooth Low Energy specifically for ESP32 devices. It supports JSON-RPC for tool discovery and invocation, handles message fragmentation for BLE MTU constraints, and includes a practical WiFi provisioning example. This BLE-only transport solution is ideal for embedded devices where WiFi or HTTP transports are unnecessary or too resource-intensive.
