About

PhyMCP is an ESP-IDF component library defining a physical device control protocol for nearby IoT devices. It enables agent hosts to discover devices via ESP-NOW, retrieve tool lists, execute tools, and send heartbeat requests with predictable timeouts. A Python MCP host interface wrapper translates PhyMCP to standard MCP endpoints. Currently experimental; requires custom firmware, serial bridges, and authorization policies.
