# Calculator Tools

> Create a hosted calculator, tracker, tool, or game with AI. No coding required. You stay the owner.

Calculator Tools hosts public one-page web apps at calculator.tools. People create apps in the browser, through ChatGPT custom GPTs, or through MCP from Cursor, Claude, or ChatGPT.

## MCP

- [MCP docs](https://calculator.tools/mcp/): how to connect Cursor, Claude, and ChatGPT
- MCP server URL: https://api.calculator.tools/mcp/
- Registry name: tools.calculator/mcp
- [server.json](https://calculator.tools/server.json): MCP registry metadata

Add the MCP server URL as a custom MCP server. Sign in with Google. Click Approve. Then ask the assistant to create an app. It returns a public calculator.tools URL.

## Optional

- [Create](https://calculator.tools/create/): make an app on the website
- [ChatGPT custom GPTs](https://calculator.tools/chatgpt/): Automatic Programming and other official GPTs
- [Browse apps](https://calculator.tools/tag/)
