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

• Server URL: https://utility-matrix.com/mcp (Streamable HTTP, JSON-RPC 2.0).
• Claude: add Utility Matrix from the Connectors Directory, or open Settings, then Connectors, then Add custom connector, and paste the URL.
• Other MCP clients (Claude Code, Cursor, VS Code, Codex): add a remote HTTP MCP server with the same URL.

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.

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.
