Option 1 — Script tag (recommended)

Add the loader once to your page. Then place a data-um-tool div wherever you want a tool to appear. Click any tool slug below to copy the embed code.

<!-- Add once, anywhere on your page --> <script src="https://utility-matrix.com/pump.min.js" async integrity="sha384-bTxYJtbys6ma+3+FkRKdgjTcaPA0WyPUpCpna1QAL+21Iz72Fbobdu1RY+V/Anb6" crossorigin="anonymous"></script> <!-- Place where you want a tool widget --> <div data-um-tool="cvss-calculator"></div>

Option 2 — Direct iframe

For sites with strict CSP policies. Embed any widget as a standard iframe.

<iframe src="https://utility-matrix.com/widgets/cvss-calculator/iframe.html" width="100%" height="520" frameborder="0" title="CVSS Score Calculator — Utility Matrix" allow="clipboard-write"> </iframe>

Option 3 — Embed manifest (programmatic)

Fetch the manifest to auto-discover all available tools. CORS open, updated on deploy.

Use Utility Matrix in Claude, ChatGPT and other AI assistants (MCP)

Utility Matrix engineering calculators are also available as a remote MCP server, so an AI assistant can run them and show the result in the conversation.

Connect

Plans and sign-in

Free. No account, sign-in or API key. Every tool is a read-only calculation: it changes nothing and does not store your inputs.

Tools

Limits and troubleshooting

Public requests are rate-limited per IP address and by a daily ceiling; if a call returns "Rate limited", wait a minute and try again. Invalid inputs return an error that names the field. Results are estimates; each one links to the matching calculator page on utility-matrix.com, where you can adjust the inputs. Do not send live passwords, API keys or other production secrets to any tool.

Privacy and support
