sigrok MCP Server
Wraps sigrok-cli to give Claude direct access to logic analyzers and protocol decoders. You get tools to scan for connected hardware, capture data from devices, and decode 100+ protocols including I2C, SPI, UART, and CAN. The server parses raw sigrok-cli output into structured JSON, handling everything from listing supported decoders to checking firmware availability. Ships as a Docker container that communicates over stdio. Useful when you need to debug embedded systems or reverse engineer serial protocols and want Claude to analyze the captures. Some devices like the Kingst LA2016 need firmware files mounted separately since they can't be bundled for licensing reasons.
