fldigi-mcp
All 174 XML-RPC methods of fldigi 4.2.13, grouped into tools. It also hunts for signals in the receiver audio, reads the Signal Browser on a fldigi with a proposed patch, and gives band guidance. It will not transmit until you set a callsign.
fldigi-mcp →wsjtx-mcp
Controls WSJT-X through its UDP message protocol. It reads decodes, answers a CQ and collects completed QSOs for the logger. For FT8, FT4, JT65, MSK144, Q65 and WSPR.
wsjtx-mcp →n3fjp-mcp
Logs contacts to Amateur Contact Log and the more than 100 N3FJP contest loggers, through the TCP API they share. Its log_qso sequence has been verified, and tiered safety levels protect the log database.
n3fjp-mcp →serial-console-mcp
Lets the assistant work a serial console. That covers routers and switches, transceivers over CI-V and CAT, rotators over GS-232, and anything else with a serial port. Tested live on a Juniper EX2200.
serial-console-mcp →mcp-host-bridge
A TCP and UDP relay. It pinches a hole into the sandbox so a local MCP server can reach a program on another computer.
mcp-host-bridge →The Ham Radio Model
A small language model being built to read a contest exchange through noise, as an experienced operator does. It has two parts, qso-resolver and qso-mcp, and both are still under development. The capture rig that collects its training data reports on the dashboard.
The Ham Radio Model →The Signal Browser methods (browser.get_channels, browser.clear) and the RSID methods (rsid.get_hits, rsid.clear) are patches offered to the fldigi maintainer on w1hkj/fldigi issue 55 on 11 and 16 September 2026. They have not been merged. On a stock fldigi, the tools answer with a hint and nothing else changes.
