01 · Install Sigrok

Claude Code

claude mcp add daedalus-mcp-sigrok -- uvx mcp-sigrok

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "daedalus-mcp-sigrok": {
      "command": "uvx",
      "args": [
        "mcp-sigrok"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.
