What it is
TestBench.tools: the homepage
TestBench.tools is a collection of free, browser-based calculators and protocol decoders designed for test and measurement engineers, embedded developers, and industrial automation professionals. It provides 58 tools covering CRC and checksum calculations (Modbus, CCITT, CRC-32, CRC-8), protocol frame decoding (Modbus, NMEA, CAN, MIL-STD-1553, ARINC 429), PLC address conversion and scaling for multiple brands, sensor mathematics including RTD and thermistor calculations, and data format conversions.
All tools run entirely in the browser with no account sign-up required. Every calculation is stateless—inputs are never stored, logged, or transmitted, making it suitable for working with sensitive customer or lab data. The site is available as an MCP server for integration with Claude Code and other MCP clients, allowing the tools to be called directly by AI assistants. Tools are verified against published specifications and golden test vectors.

Quick answers
What is TestBench.tools?
TestBench.tools is a collection of free, browser-based micro-tools for test and measurement engineers, embedded developers and industrial automation professionals. It includes CRC calculators, protocol decoders, PLC scaling math, sensor equations and measurement file converters that run entirely in your browser without requiring sign-up or sending data to any server.
Where does my data go when I use TestBench.tools?
Your data never leaves your computer. All calculations and file conversions run in your browser on the client-side. The site has no accounts, no upload servers, and no way to store your inputs—they are computed and discarded immediately.
How accurate are the calculations?
The calculation engines are covered by an automated test suite pinned to published check values and golden vectors. If a tool page states a number, a test asserts it. Reports of wrong values get priority when you contact the developer.
Can I use TestBench.tools from Claude Code?
Yes. Every calculator on the site is also an MCP server, so Claude Code and other MCP clients can call the tools directly. You can install the remote MCP server in one line or run a local version that works offline.
