Returns the paycheck lines, a link to the matching page, the publications and the date they were checked, and a disclaimer. Estimate only.
calculate_quarterly_estimated_tax
Work out 2026 federal quarterly estimated tax payments with the IRS safe harbor rules (90% of this year's tax or 100%/110% of last year's), minus withholding, with the four due dates. Same math as the auracalcs.com quarterly estimated tax calculator. Estimate only.
compare
compare_1099_vs_w2
Compare a 1099 hourly contract with a W-2 salary offer, counting the extra self-employment tax, 401(k) match, health insurance and business expenses. Returns which pays more, by how much, and the break-even 1099 hourly rate. Same math as the auracalcs.com 1099 vs W-2 calculator. Estimate only.

AuraCalcs — questions

Answers built from our own checks of this server.

What can AuraCalcs do?
It exposes 5 tools, read directly from the server on our last check. Among them: calculate_1099_tax, calculate_paycheck, calculate_quarterly_estimated_tax, compare_1099_vs_w2, convert_hourly_to_salary. 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 →
Is AuraCalcs working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 211 ms. The bar chart above shows every period we have measured.
How do I connect AuraCalcs?
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 AuraCalcs need an API key?
No. AuraCalcs completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is AuraCalcs?
It answers our handshake in 211 ms on average, which is faster than 67% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
