DecisionsCalc calculators — questions

Answers built from our own checks of this server.

What can DecisionsCalc calculators do?
It exposes 33 tools, read directly from the server on our last check. Among them: australia_parental_leave_pay, australia_private_health_rebate_mls, canada_ei_maternity_parental, ireland_budget_2027_take_home, ireland_budget_2027_welfare, ireland_can_i_retire and 27 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
What is DecisionsCalc calculators mostly used for?
Its tools cluster around ireland, australia and stamp. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is DecisionsCalc calculators working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 210 ms. The bar chart above shows every period we have measured.
How do I connect DecisionsCalc calculators?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does DecisionsCalc calculators need an API key?
No. DecisionsCalc calculators completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 33 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is DecisionsCalc calculators?
It answers our handshake in 210 ms on average, which is faster than 64% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is DecisionsCalc calculators open source?
We cannot say either way: written in TypeScript and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
