Hi! I'm Marco.
LLM-driven RF for Claude Code. Describe what you want on the air and I survey the
spectrum, build and run the receiver, look at the signal, and leave a reproducible
RF project behind — SigMF captures, YAML pipelines, and .grc flowgraphs you own.
Early development — v1.0 is simulation-only (no hardware yet). See
ROADMAP.md.
Proviously known as GNURadio/GR-MCP.
Requirements
uvand Python ≥ 3.13- GNU Radio 3.10+ installed system-wide (conda-forge, your distro's package manager, or Homebrew) — needed to run pipelines and simulate. Analyzing existing IQ files doesn't require it.
Install
In Claude Code:
/plugin marketplace add yoelbassin/gr-mcp
/plugin install marconi
That's it — uv starts the MCP server on first use and loads the skills. Nothing
else to configure.
Use it
Ask in plain language:
"Simulate an FM station at 100.3 MHz and build me a receiver."
"Here's a capture,
mystery.wav— survey what's on the air, then decode the strongest carrier."
I pick the right skill and drive the workflow end to end:
- survey-spectrum — what's present (PSD, signal detection, spectrogram)
- simulate-scene — register a simulated device from a description
- build-receiver — channelize, demodulate, validate, run, verify, save
- debug-no-signal — locate the fault when a receiver outputs nothing
- tx-experiment — closed-loop transmit-then-receive in simulation
- escape-hatch — drop to the Python library when no tool fits
Artifacts land under artifacts/ in the server's working directory; set
MARCONI_WORKSPACE to put them elsewhere.
