## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 1165 tokens (~83/item across 14 items; 13 tools + 1 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100

  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## MCP tools (13)

### `capture_data` (~198 tokens)

Capture communication data from a connected device and save to file. Either 'samples' or 'time' must be specified.

Input parameters:

- `channels` (string): Channels to use (e.g. 'D0,D1,D2')
- `config` (string): Device configuration (e.g. 'samplerate=1M')
- `conn` (string): Connection string for serial/network devices (e.g. '/dev/ttyUSB0:serialcomm=115200/8n1')
- `driver` (string, required): Hardware driver ID (e.g. 'fx2lafw', 'demo')
- `output_file` (string): Output filename (auto-generated if omitted)
- `samples` (number): Number of samples to acquire
- `time` (number): How long to sample in milliseconds
- `triggers` (string): Trigger configuration (e.g. 'D0=r')
- `wait_trigger` (boolean): Wait for trigger before capturing

### `check_firmware_status` (~44 tokens)

Check firmware file availability in standard sigrok firmware directories. Returns which directories exist and what firmware files are present. Use this to diagnose device detection issues caused by missing firmware.

### `decode_protocol` (~146 tokens)

Decode protocol data from a captured file using sigrok protocol decoders.

Input parameters:

- `annotations` (string): Decoder annotation filter (e.g. 'uart=rx-data')
- `input_file` (string, required): Input filename
- `input_format` (string): Input format (e.g. 'vcd', 'binary')
- `json_trace` (boolean): Output in Google Trace Event JSON format
- `meta_output` (string): Decoder meta output filter (e.g. 'uart=baud')
- `protocol_decoders` (string, required): Protocol decoders to apply (e.g. 'uart:baudrate=9600')
- `show_sample_numbers` (boolean): Include sample numbers in output

### `get_device_profile` (~88 tokens)

Look up a device profile by name, model, manufacturer, or *IDN? response string. Returns connection settings (baudrate, parity, etc.), supported commands with examples, and device-specific notes. Use this before serial_query to get the correct settings for a device.

Input parameters:

- `query` (string, required): Device name, model, manufacturer, or *IDN? response string to match against

### `list_input_formats` (~27 tokens)

List all supported input file formats. Returns an array of {id, description} objects.

### `list_output_formats` (~27 tokens)

List all supported output file formats. Returns an array of {id, description} objects.

### `list_supported_decoders` (~28 tokens)

List all supported protocol decoders. Returns an array of {id, description} objects.

### `list_supported_hardware` (~27 tokens)

List all supported hardware drivers. Returns an array of {id, description} objects.

### `scan_devices` (~225 tokens)

Scan for connected hardware devices. Returns {devices, warnings, hint} where devices is an array of {driver, description} objects. Warnings indicate firmware-related issues for devices that could not be initialized.

When driver and conn are provided, performs a targeted scan for a specific serial/network device (e.g. SCPI instruments). SCPI driver categories: 'scpi-dmm' (multimeters), 'scpi-pps' (power supplies), or vendor-specific drivers like 'rigol-ds' (oscilloscopes). Example: driver='scpi-dmm', conn='/dev/ttyUSB0:serialcomm=115200/8n1'.

Input parameters:

- `conn` (string): Connection string for targeted scanning (e.g. '/dev/ttyUSB0:serialcomm=115200/8n1', 'tcp-raw/192.168.1.100/5555')
- `driver` (string): Hardware driver ID for targeted scanning (e.g. 'scpi-dmm', 'scpi-pps', 'rigol-ds')

### `serial_query` (~200 tokens)

Send a command string over a serial port and return the device response. Works with any serial-attached instrument that accepts text commands (e.g. SCPI). Independent of sigrok-cli.

Input parameters:

- `baudrate` (number): Baud rate (default 9600)
- `command` (string, required): Command to send (e.g. '*IDN?', 'MEAS:VOLT:DC?')
- `databits` (number): Data bits: 5, 6, 7, or 8 (default 8)
- `parity` (string): Parity: none, odd, even, mark, space (default 'none')
- `port` (string, required): Serial device path (e.g. '/dev/ttyUSB0')
- `stopbits` (string): Stop bits: 1, 1.5, 2 (default '1')
- `timeout_ms` (number): Read timeout in milliseconds (default 1000)

### `show_decoder_details` (~53 tokens)

Show detailed information about a specific protocol decoder, including options, channels, annotation classes, and documentation.

Input parameters:

- `decoder` (string, required): Protocol decoder ID (e.g. 'uart', 'spi', 'i2c')

### `show_driver_details` (~57 tokens)

Show detailed information about a specific hardware driver, including supported functions, scan options, and connected devices.

Input parameters:

- `driver` (string, required): Hardware driver ID (e.g. 'demo', 'fx2lafw', 'rigol-ds')

### `show_version` (~19 tokens)

Show sigrok-cli version information, including library versions.
