Mcp Sigrok
Wraps sigrok-cli as MCP tools so you can control logic analyzers and decode protocol captures directly from Claude. Exposes operations like scanning for devices, capturing samples from hardware, loading session files, and running protocol decoders for I2C, SPI, UART, and more. You get tools for version checks, listing supported drivers and decoders, configuring device parameters, and capturing either by sample count or time duration. Requires sigrok-cli installed locally, which supports a wide range of logic analyzer hardware from Saleae clones to Cypress FX2 based devices. Useful when you're debugging embedded systems and want to analyze signal captures or configure hardware without leaving your conversation.
