@cyanheads/fcc-spectrum-mcp-server Search FCC radio licenses, find nearby transmitter sites, and see who is licensed on a frequency via MCP. STDIO or Streamable HTTP. 5 Tools • 1 Resource

Overview

US radio spectrum licensing from the FCC Universal Licensing System (ULS), served from a local SQLite index of the FCC's weekly and daily bulk files. Look up a callsign, licensee, or FCC Registration Number (FRN); read a license's sites, antennas, frequencies, power, and emission designators; find licensed transmitter sites within a radius of a point; and see who is authorized on a frequency or band, market-area spectrum blocks included. No API key, and no call to the FCC at request time. Runs as a stdio process or a local Streamable HTTP server.

The default index covers land mobile (private, commercial, and broadcast auxiliary), microwave, cellular, market-area wireless, paging, coast stations, broadband radio (BRS/EBS), and amateur licenses, plus spectrum leases. GMRS, ship, and aircraft licenses are opt-in. Broadcast stations (AM/FM/TV) and satellite earth stations are separate FCC systems and are not included.
