Repository

fw-context builds a compiler-accurate semantic index of your C/C++ firmware from compile_commands.json and the libclang AST. Instead of reconstructing the program from text, the LLM queries a persistent index for symbol definitions, callers, callees, callback registrations, function pointer assignments, inheritance, and active source code. 31 MCP tools. Powered by libclang + SQLite + FTS5 + vector search.

For Zephyr, PlatformIO, Mbed OS, Arduino, FreeRTOS — any build that produces compile_commands.json.
