Connects Claude to rftools.io's engineering calculator library and simulation pipeline. You get 213 calculators that run locally (microstrip impedance, link budgets, buck converter sizing, filter design) plus 13 server-side simulation tools that require an API key (NEC2 antenna modeling, FDTD, Monte Carlo tolerance analysis, SMPS stability, EMI estimation). Calculators return instant results with units and formulas. Simulations are queued jobs that take 15 to 120 seconds and consume monthly quota. Free tier gets 5 simulation runs per month, paid tiers scale to 10,000. Useful if you're designing RF circuits, power supplies, or PCBs and want validated math without leaving your editor.
