Calculator Tools vs Cursor

The short answer

Calculator Tools hosts a public static web app on your account. You get a calculator.tools URL. Cursor is an AI-centered code editor. It edits files on your computer (or in a cloud agent workspace). They are complementary. MCP is how Cursor can publish here after you approve access.

Use Calculator Tools when the deliverable is a public URL, not a repo. You can skip the IDE and start on Create. Use Cursor to write and refactor code, then publish the hosted files here.

What they do

Cursor is an IDE. You open a project, the agent edits files, and you run or commit that project yourself. It is for software work.

Cursor can call MCP servers. Calculator Tools MCP is one of those servers. Cursor is not the host. The host is this site.

What Calculator Tools does

This site stores app files and serves a public page. You can skip Cursor entirely and use Create or GPTs.

Files live in one directory. Typical files are index.html plus CSS, JavaScript, JSON, SVG, or similar static files.

When Cursor is connected with MCP, the assistant can create and update apps on your account. You stay the owner.

Free accounts can publish 3 apps. Pro ($5.99/month) raises the limit to 25.

Where they differ

Feature	Cursor	Calculator Tools
Kind of product	Editor / agent	App host
Files live	Your project	This site's app files
Public URL	Only if you deploy	Yes, on publish
Works without an IDE	No	Yes
MCP	Client	Server

MCP connects both products. Cursor writes files. Calculator Tools hosts them. A local index.html is not a hosted app until you publish it here.

When to use each

Use Calculator Tools without Cursor when you only need a hosted static tool. Open Create.
Use both when Cursor should publish the tool through MCP instead of leaving HTML on disk.
Use Cursor to build a real codebase, tests, and git history. When the output is a public calculator, still publish here.
Use Replit if you want the IDE in the cloud. See Replit. The static host is still this site.

Limits

Calculator Tools is not an IDE. It will not replace Cursor for application development.

Cursor does not host calculator.tools URLs unless MCP is connected.

A local index.html in Cursor is not a hosted app until something deploys it. MCP is that path for this host.

Next step

Connect MCP in Cursor and ask it to publish, or open Create in the browser. The first 3 apps are free.
