Curvecall — questions

Answers built from our own checks of this server.

What can Curvecall do?
It exposes 11 tools, read directly from the server on our last check. Among them: bundle_check, contract_check, deployer_history, precheck, quote_buy, quote_sell 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 →
What is Curvecall mostly used for?
Its tools cluster around quote and token. 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 Curvecall 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 261 ms. The bar chart above shows every period we have measured.
How do I connect Curvecall?
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 Curvecall need an API key?
No. Curvecall 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 Curvecall?
It answers our handshake in 261 ms on average, which is faster than 55% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
