What can PlainText Wallet Approval Checker do?

Is PlainText Wallet Approval Checker 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 412 ms. The bar chart above shows every period we have measured.

How do I connect PlainText Wallet Approval Checker?

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 PlainText Wallet Approval Checker need an API key?

No. PlainText Wallet Approval Checker completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is PlainText Wallet Approval Checker?

It answers our handshake in 412 ms on average, which is faster than 39% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
