CrossFin — questions

Answers built from our own checks of this server.

What can CrossFin do?
It exposes 16 tools, read directly from the server on our last check. Among them: call_paid_service, compare_exchange_prices, create_wallet, find_optimal_route, get_analytics, get_balance and 10 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 CrossFin 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 1796 ms. The bar chart above shows every period we have measured.
How do I connect CrossFin?
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 CrossFin need an API key?
No. CrossFin completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 16 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is CrossFin?
It answers our handshake in 1796 ms on average, which is faster than 1% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use CrossFin?
The npm package crossfin-mcp was installed 73 times in the last week. Week over week that is +9%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is CrossFin open source?
Yes — it is published under the MIT licence, written in TypeScript, 1 stars on GitHub and 5 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
