iota-mcp
MCP server for Islands on the Air (IOTA) — group lookup, island search, DXCC mapping, nearby groups, and programme statistics through any MCP-compatible AI assistant.
Part of the qso-graph project. No authentication required — all IOTA data is public.

Example Prompts
- "Look up IOTA group NA-005"
- "Search for islands named Shetland"
- "What IOTA groups are near Boise, Idaho?"
- "Show me all islands in EU-005"
- "What IOTA references map to DXCC 291?"
- "Give me IOTA programme statistics"
Data Source
Data comes from the official IOTA website JSON downloads:
- fulllist.json — complete group/subgroup/island hierarchy (~1.3 MB)
- dxcc_matches_one_iota.json — 1:1 DXCC-to-IOTA mapping (~3.5 KB)
Data is downloaded once and cached for 24 hours (IOTA refreshes daily at 00:00 UTC).
