Electrical / runnable MCP tool
Run the Voltage Drop Calculator in your AI assistant
Through the free Intry MCP server, ChatGPT, Claude, or Cursor runs this exact calculator and hands back a verdict and the cited source, not a guess. Tool name: voltage_drop.
Ask your assistant
Once Intry is connected, type a question like these. The assistant recognizes the job and calls the voltage_drop tool, then answers with the number, the verdict, and the citation.
