About Rftools

MCP server for rftools.io — 203 RF & electronics calculators + 13 server-side simulation tools for AI agents.

Config

Add this server to your MCP-compatible client using the configuration below.

{
  "mcpServers": {
    "rftools": {
      "command": "npx",
      "args": [
        "-y",
        "rftools-mcp"
      ],
      "env": {
        "RFTOOLS_API_KEY": "rfc_your_key_here"
      }
    }
  }
}

Tools

List available RF & electronics calculators. Optionally filter by category: rf, pcb, power, signal, antenna, general, motor, protocol, emc, thermal, sensor, unit-conversion, audio.

Get detailed information about a specific calculator including its inputs, outputs, and formula. Use this to understand what parameters a calculator needs before running it.

Run an RF/electronics calculator with the given inputs. Use get_calculator_info first to see required inputs.

List the 14 server-side RF simulation tools available via API key. These require RFTOOLS_API_KEY (set in env). Free tier: 5 runs/month. Pro: 100/month. API tier: 10 000/month.

Submit a server-side RF simulation job and wait for the result. Requires RFTOOLS_API_KEY environment variable. Simulations typically complete in 15–120 seconds; queue wait may add more time. Use list_simulation_tools to see available jobTypes and required params.

Overview

What is Rftools?

Rftools is an MCP server that gives AI agents access to 213 validated RF and electronics calculators and 13 server-side simulation tools from rftools.io. It is designed for engineers using Claude, Cursor, or any MCP-compatible AI assistant.

How to use Rftools?

Install via npx -y rftools-mcp and configure your MCP client with the provided JSON config. For calculator‑only use, no API key is needed; to enable simulation tools, add an API key obtained from your rftools.io dashboard.
