The short answer
create_site is Ginta's MCP tool for a new site. Use Calculator Tools when you want a calculator, tracker, or game on your own calculator.tools account. Connect MCP. The assistant calls webappCreate.
Ginta's server is https://ginta.app/mcp. This host's server is https://api.calculator.tools/mcp/.
What this call does
Ginta's Claude Code guide says hand-written pages go out through create_site with the files, and index.html is required. Later small edits use update_site. A guide read is get_guide. A framework build can call create_site without files, receive an upload link, and POST a zip.
Ginta says the free plan includes 20 sites at a ginta.page address with a badge. A custom domain is on paid plans, from €5 a month, according to that page.
The site lives in Ginta. It does not appear in a Calculator Tools dashboard.
What Calculator Tools does
Calculator Tools is built for a public static tool: one app, a URL, an owner.
Files live in one directory. index.html, CSS, JavaScript, and other static files.
You stay the owner. Remix copies a public app on this site into your account.
Free accounts can publish 3 apps. Pro ($5.99/month) raises the limit to 25.
How to use MCP for this job
Add https://api.calculator.tools/mcp/ instead of the Ginta URL when the deliverable is a calculator.tools page. Sign in with Google. Click Approve.
Call the MCP tool create_site with files. index.html is required. The server calls webappCreate, then webappfileCreate. A later file change can call write_site_files with webapp_id and files.
You can also skip MCP and open Create.
Limits
Calculator Tools does not run create_site. It does not include Ginta forms, bookings, or shop blocks.
It does not deploy a Vite or Next server build. Send static files. If you need that upload-link flow for a large framework build, Ginta documents that path. For a self-contained tool, publish here.
Check formulas before you share the URL.
Next step
Open Create or connect MCP. The first 3 apps are free.
