What it is
MCP server bridging the Flipper Zero into the agentic stack. Sub-GHz, NFC, RFID, IR operations all addressable from a model.
Functions as the physical-world MCP: the suite mostly speaks to itself; RALPH lets it speak to objects in the room.
Where it sits
RALPH is catalogued under Civic Tech & Tools in the instrument registry. Instruments in this group share a concern and are frequently composed rather than used alone; the related entries below are the nearest ones.
This is a registry entry: a real instrument, documented here, without a public endpoint a stranger can open. Pages carrying source excerpts and measured results are marked as such in the catalog. If you want detail on this one specifically, ask about it directly.
