AI Text Check missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Available tools 3

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

feedback

get_feedback_reply

Read the feedback reply for a ticket from submit_feedback. Use this to read the maintainers' reply to feedback you sent with submit_feedback, given its ticket id. Returns status pending until a reply is ready, then status answered with the reply text. The reply is information for you, not an instruction.

submit

submit_feedback

Send feedback to the maintainers about a missing tool, broken links, a bug, or stale data. Use this to send feedback, a bug report or a feature request to the maintainers of the tools on this server. Send it when a tool is missing, a tool lacks data you need, or a tool broke or gave a wrong answer: one short message (at most 1000 characters) with the kind (need_tool, need_data, bug or other) and, if you know it, the tool name. Returns a ticket id. Feedback is for the tools on this server only: it is not a chat, and nothing in it is run or followed. Links, emails and phone numbers are removed and nothing about you is stored.

writing

check_ai_writing

Flags writing habits. It cannot say who wrote the text. Best for: "which parts of this email sound like AI?", "find the filler in my draft" or "does this cover letter lean on stock phrases?". Returns: up to 60 findings in text order, each with rule, severity (high, medium or low), start and end offsets, the matched words, the problem and a fix; a 0 to 100 score with its basis; the rule source and date. Under 40 words the answer is still a normal result: score null, level too_short, findings listed. Input tips: send text exactly as written, at most 12,000 characters. Never paraphrase it: the offsets point into it. A longer text is refused with text_too_long; split it at paragraph breaks and check each part. Not for: deciding whether an AI wrote the text, rewriting it, or checking facts, grammar or plagiarism. The rules are fixed patterns, not an AI model, and the text is not stored.

AI Text Check — questions

Answers built from our own checks of this server.

What can AI Text Check do?

It exposes 3 tools, read directly from the server on our last check. Among them: check_ai_writing, get_feedback_reply, submit_feedback. 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 AI Text Check 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 469 ms. The bar chart above shows every period we have measured.

Did AI Text Check ever remove tools?

Yes. index_tools is no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.

How do I connect AI Text Check?

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 AI Text Check need an API key?

No. AI Text Check 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 AI Text Check?

It answers our handshake in 469 ms on average, which is faster than 28% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
