Opencrater MCP — questions

Answers built from our own checks of this server.

What can Opencrater MCP do?
It exposes 3 tools, read directly from the server on our last check. Among them: opencrater_get_started, opencrater_network_stats, opencrater_supported_tools. 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 Opencrater MCP 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 946 ms. The bar chart above shows every period we have measured.
How do I connect Opencrater 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 Opencrater MCP need an API key?
No. Opencrater MCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Opencrater MCP?
It answers our handshake in 946 ms on average, which is faster than 6% 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 Opencrater MCP?
The npm package opencrater-mcp was installed 23 times in the last week. Week over week that is -62%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Opencrater MCP open source?
Yes — written in JavaScript 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.
