Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

license
license_detail
Full data for a single FCC license by call sign — licensee, locations with coordinates, antennas, paths, frequencies. Returns Markdown.
path
path_profile
Metadata for a single microwave path on a license. Identified by the ULS USI (per-license integer) and the path number within that license. The HTML page has an SVG elevation chart with terrain + line of sight + Fresnel zone; the Markdown response carries the endpoints, length, and frequency but not the chart.
search
search
Free-text search across FCC call signs and licensee entity names. Returns up to 50 hits. Use this when the user names a callsign or company but you don't know the exact identifier yet.
tower
tower_detail
Full data for an antenna structure by ASR registration number — owner, location, height, declared licensees on the tower, microwave paths terminating there, and licensees within 50 m by spatial proximity. Returns Markdown.

fccdb — questions

Answers built from our own checks of this server.

What can fccdb do?
It exposes 4 tools, read directly from the server on our last check. Among them: license_detail, path_profile, search, tower_detail. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is fccdb working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 8000 ms. The bar chart above shows every period we have measured.
Is fccdb still maintained?
The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.
The registry lists fccdb as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect fccdb?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does fccdb need an API key?
No. fccdb completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
