Tools

• get-signal: Provide all changes of the specified signal name to the model’s context. This is useful for large waveform files with many signals where you cannot fit the entire VCD file into the model’s context window.
  • Can optionally specify a start and end timestamp range for the model to look at.

Installation

uv pip install --system mcp-vcd

And add the following to your claude_desktop_config.json:

"mcpServers": {
  "mcp-vcd": {
    "command": "uv",
    "args": [
      "run",
      "mcp-vcd"
    ]
  }
}
