Crosspad Mcp
crosspad/crosspad-mcp
Gives Claude direct control over the CrossPad embedded development workflow. Exposes 28 tools spanning builds (PC simulator and ESP-IDF firmware), flashing over UART or OTA, simulator interaction (screenshots, MIDI/pad input injection, runtime stats), Catch2 test execution, and a package manager for the crosspad-apps registry. Also surfaces code search across repos (symbol lookups, interface implementations, capability flags) and git operations (status, diff, submodule updates, commits). Three workspace resources provide session context without tool calls. Useful when you're iterating on embedded firmware or simulator apps and want Claude to handle the build/test/flash cycle, inject test inputs, or scaffold changes across the multi-repo structure.

crosspad-mcp
Talk to your CrossPad. Let Claude do the toolchain.
crosspad-mcp is an MCP server that teaches Claude Code (or any MCP client) how to develop for the CrossPad pad controller. You say "flash the new build and check that it boots"; it runs the ESP-IDF build, asks you to confirm the flash, opens the console, runs the smoke scenario and tells you what happened — with the hardware traps already built in, so you don't have to remember which serial port reboots the board when you open it.
