Utilities

Handy primitives for agents: QR codes and unit conversion.

UtilitiesMCP + x402$0.001 Live

Overview

Small, fast utilities agents reach for constantly. Generate a QR code (SVG) for any text or URL, and convert values between units — length, mass, volume, speed, area, digital storage, time and temperature. Pure compute, no external dependencies. Available over MCP and as pay-per-call x402 HTTP endpoints.

Connect it

Add the remote MCP server to any client, or call the x402 HTTP endpoint directly.
