OERadio MCP

An open-source Model Context Protocol server providing amateur radio tools and calculations for IARU Region 1 operators, including band plans, EIRP, cable loss, antenna gains, and Austrian callsign lookups.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Vendor documentation

What its tools do

17 tools, grouped by the hints the server advertises. Hints are self-declared, not verified behavior.

Not annotated (17)

17 of 17 have a description · 0 of 17 declare behavior hints · 15 of 15 with parameters document them all

Checks and signals

Each line is separate evidence, not a trust score.

  • Passed Endpoint answered the live check ·
  • Availability 1 of 1 checks passed in 30 days

What you can do with it

  • Get IARU Region 1 band plan for a specific band
  • Calculate EIRP/ERP from power, cable loss, and antenna gain
  • Search Austrian callsigns using official data sources
  • Calculate battery runtime for portable operation
