AI assistants (MCP)

GlobalKit's calculators and developer tools are available to AI assistants through the Model Context Protocol (MCP). When you ask an assistant a question such as "what is the net pay for a 50,000 TRY gross salary?", it can call GlobalKit, get an exact answer from the same engine that powers the calculator on this site, and show you a link that opens the same calculation with the values already filled in.

Connect

The server address is:

https://mcp.globalkit.app/mcp

It uses the Streamable HTTP transport, needs no authentication and exposes read-only tools.

• Claude: open Customize, then Connectors, choose Add custom connector, and paste the address. Pick No sign-in if you are asked how to authenticate.
• ChatGPT: in a workspace that allows custom connectors, add a new connector with the same address and no authentication.
• Any other MCP client: add a remote Streamable HTTP server with the address above. You can inspect it with the MCP Inspector.

• "What is the monthly payment on a 250,000 loan at 4.25% over 120 months?"

How the answers are built

Amounts go in and come out as decimal strings, and money is computed in integer minor units, so there are no floating-point rounding surprises. Every result includes a source_url. Opening it shows the same calculation on globalkit.app with the inputs filled in, where you can change a value, read how the formula works and see the full table. Tools that take free text (Base64, URL, JSON, hash) never put your text into the link; the link opens the empty tool.

Calculators that depend on a country's rules say which country and year they used. Results are estimates for information only; they are not financial, tax or legal advice.

Limits and privacy

• Rate limit: about 10 requests per 10 seconds per IP address. Beyond that the server answers with HTTP 429.
• Size: a request body can be up to 8 KB.
• Privacy: the server stores nothing, has no accounts and does not write your values to its logs. Cloudflare processes technical request data such as your IP address to deliver the service and limit abuse. Read the Privacy Policy for the full description.
• Availability: the service is free and provided as is; the Terms of use apply.
