SpectraMCP
Server Configuration
Describes the environment variables required to run the server.
| Name | Required | Description | Default |
|---|---|---|---|
| SPECTRAMCP_WORKSPACE | No | Local directory path for saving exported plots and IQ segments. |
Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| load_iq_fileC | Loads .wav, .iq, .sigmf-data/.sigmf-meta, or .npy into a normalized IQBuffer. |
| capture_from_sdrB | Captures a fixed-duration IQ segment from an attached RTL-SDR/HackRF/SoapySDR device. |
| list_sdr_devicesA | Enumerates attached SDR hardware and reports supported sample rates / tunable range. |
| compute_fftB | Windowed FFT with configurable window (Hann/Hamming/Blackman) and zero-padding factor. |
| render_spectrogramC | STFT spectrogram image with configurable frame size, hop, and dB dynamic range. |
| render_waterfallC | Rolling PSD waterfall across N consecutive capture segments. |
| range_doppler_mapC | 2D windowed FFT (fast-time/slow-time) over a supplied RadarCube. |
| ca_cfar_detectC | 2D Cell-Averaging CFAR detector with configurable guard/training cell geometry. |
| mvdr_beamformB | Adaptive Capon/MVDR beamformer with diagonal-loading stabilization for rank-deficient snapshots. |
| kalman_trackC | Constant-velocity Kalman tracker associating detections across sequential frames. |
| classify_modulationB | Rule-based AM/FM/OOK/FSK/PSK-family classifier using envelope, kurtosis, and spectral-flatness features. |
| micro_doppler_signatureC | Cadence-spectrum periodicity extraction for rotor-vs-flutter style signature comparison. |
| export_plotC | Saves any generated figure directly to a local folder on the user's PC. |
| export_iq_segmentC | Saves an IQ segment slice directly to a local folder on the user's PC. |
