Source code Documentation

Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

PYPI package mcp-sigrok

mcp-sigrok — MCP server for sigrok-cli

MCP server that exposes all functionality of sigrok-cli as MCP tools. sigrok-cli is a cross-platform command-line utility for the sigrok software suite, used for hardware initialization, acquisition, protocol decoding, and saving logic analyzer sessions.

Install

pip install mcp-sigrok

Requirements

  • sigrok-cli must be installed on the system
Installing sigrok-cli

Debian/Ubuntu:

sudo apt install sigrok-cli

macOS:

brew install sigrok-cli

From source:

git clone git://sigrok.org/sigrok-cli
cd sigrok-cli
./autogen.sh
./configure
make
sudo make install

Usage

As MCP Server
# Run as stdio MCP server
mcp-sigrok

Or configure in your MCP settings:

{
  "mcpServers": {
    "sigrok": {
      "command": "mcp-sigrok"
    }
  }
}
Python API
from mcp_sigrok import (
    check_sigrok_cli,
    get_version,
    list_drivers,
    scan_devices,
    capture_samples,
    load_input_file,
)

# Check if sigrok-cli is available
if cli_path := check_sigrok_cli():
    print(f"Found sigrok-cli at: {cli_path}")

# Get version info
info = get_version()

# List available drivers
drivers = list_drivers()

# Scan for devices
devices = scan_devices()

# Capture samples
result = capture_samples("fx2lafw", samples=1000)

result = capture(
    driver="fx2lafw",
    samples=1000,
    channels="0-7",
    output_format="hex"
)
Decode I2C protocol
# Load capture file and decode I2C
result = load_file(
    input_file="capture.sr",
    protocol_decoders="i2c",
    output_file="decoded.txt"
)
Scan for devices
# Find available devices
devices = scan_for_devices()
for device in devices.get("devices", []):
    print(f"Found: {device}")
