Precisioncalc MCP — questions

Answers built from our own checks of this server.

What can Precisioncalc MCP do?

It exposes 11 tools, read directly from the server on our last check. Among them: batch_calculate, business_days, calculate_metric, compound_growth, currency_convert, depreciation and 5 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 →

Is Precisioncalc MCP 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 43 ms. The bar chart above shows every period we have measured.

How do I connect Precisioncalc MCP?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Precisioncalc MCP need an API key?

No. Precisioncalc MCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 11 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Precisioncalc MCP?

It answers our handshake in 43 ms on average, which is faster than 97% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.

How many people use Precisioncalc MCP?

The npm package precisioncalc-mcp was installed 26 times in the last week. Week over week that is -7%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Precisioncalc MCP open source?

Yes — it is published under the MIT licence, written in Python and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
