What this means
MCP means Model Context Protocol. It is a connection that lets an AI assistant use extra tools. Calculator Tools MCP points those tools at the same hosting API the website uses.
The assistant can create an app, write files, list your apps, and return a public calculator.tools URL. You stay the owner.
Why it matters
Without MCP, Cursor or Claude can write HTML and stop there. With MCP, the same assistant can publish that HTML as a hosted app. In Claude, that often means an Artifact first, then a publish step to this host.
This is not a replacement for the website. It is the same publish step, started from an assistant you already use.
How it works here
Add https://api.calculator.tools/mcp/ as a custom MCP server. Sign in with Google. Click Approve. Then ask the assistant to create an app.
A dashboard login code is an optional bearer token for setups that still want a header. Treat the code like a password.
Full install steps live on the MCP page. This definition is the short version.
