Query pre-processed Ghidra firmware analysis databases for embedded firmware reverse engineering. Use when the user asks about firmware binaries, function lookups, cross-references, call graphs, symbol resolution, disassembly, or binary patching tasks. Supports queries like "find function at address", "show callers of X", "get disassembly for function Y", "what references this address", or "help me patch this firmware". Each firmware project has a corresponding SQLite database in /mnt/user-data/uploads/firmware-dbs/.
