We send a real MCP handshake every 15 minutes. Over the last 24 hours 30 of 30 checks got a reply (100.0%), average response time 581 ms. The bar chart above shows every period we have measured.

How do I connect Nova Inbox Agent by Nova (CIVAI)?

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 Nova Inbox Agent by Nova (CIVAI) need an API key?

No. Nova Inbox Agent by Nova (CIVAI) completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Nova Inbox Agent by Nova (CIVAI)?

It answers our handshake in 581 ms on average, which is faster than 25% 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.
