profanity

check_profanity

Detect English profanity in text (word list with leetspeak, look-alike letters, repeated letters, dotted/spaced letters and hidden characters handled) and return the matched terms, their positions (UTF-16 start/end in your text) and, unless censor is false, a censored copy of the same length. Common innocent words (Scunthorpe, cockpit, Shiite, cumin) are whitelisted; it does not understand context and is English only. Text up to 10240 UTF-8 bytes; it is not stored or logged. matches is capped at 50 here (match_count is the full total). Read-only. Same engine, keys and limits as POST /v1/check.

CussCheck — questions

Answers built from our own checks of this server.

What can CussCheck do?

It exposes 1 tools, read directly from the server on our last check. Among them: check_profanity. 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 CussCheck 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 117 ms. The bar chart above shows every period we have measured.

How do I connect CussCheck?

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 CussCheck need an API key?

No. CussCheck completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is CussCheck?

It answers our handshake in 117 ms on average, which is faster than 89% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
