AI Text Check in Pi
Flag AI-writing tells in text. The MCP server is https://aitext.openkrill.app/mcp. No key. The steps below are only for Pi. A call to check_ai_writing was checked against that server on 2026-10-01.
What this server answers
Paste a draft and see the habits that make writing read like it came from an AI model, each marked at its exact place with a plain-language fix.
Ask "which parts of this email sound like AI?", "check my blog post for filler" or "does this cover letter lean on stock phrases?".
AI Text Check looks for overused words and stock openers, hedging openers, sycophantic praise and chatbot sign-offs, generic closers, inflated claims, unnamed experts, "not just X, it's Y" turns, lists of three, heavy em-dash use, decorative bold bullets, and runs of sentences with the same length or the same opening.
Every finding gives the rule, a severity, the start and end offsets, the matched words, why it reads that way and a concrete fix. A score from 0 to 100 sums them up, and the answer states how the score is worked out.
The rules are fixed patterns, not an AI model, so the same text always gives the same answer. They are written for this service; the categories follow the open-source blader/humanizer catalogue (MIT licence) and Wikipedia's "Signs of AI writing".
A finding is a place to look at, not proof of who wrote the text: careful writers use all of these on purpose, and the tool is not an AI detector. It does not rewrite the text.
The text is checked and forgotten: it is never stored, and the only lasting record is a daily count of calls. It is limited to 12,000 characters (about 2,000 words); a score needs at least 40 words.
What it can do
- Flags overused words, stock openers and filler phrases
- Flags hedging openers, generic closers and chatbot sign-offs
- Flags sycophantic praise and inflated claims
- Flags lists of three, heavy em-dash use and decorative bold bullets
- Flags runs of sentences with the same length or opening
- Gives start and end offsets, a severity and a fix for each finding
- Gives a 0 to 100 score and states how it is worked out
- Uses fixed rules, with no AI model, and never stores the text
Tools
check_ai_writing, Check text for AI-writing tells. Flags writing habits. It cannot say who wrote the text. It marks each habit with a fix and a 0 to 100 score. Use it when the user asks which parts read like AI writing, for example "find the filler in my draft", "what makes this email read as machine-written". Pass the text exactly as written, at most 12,000 characters. Returns up to 60 findings in text order, each with a rule id, a severity (high, medium or low), start and end offsets in the text, the matched words, why it reads that way and a plain-language fix, plus a 0 to 100 score with how it was worked out, the source and the date of the rules. The rules are fixed patterns, not an AI model. A finding or a low score is not proof of who wrote the text, so it cannot say whether an AI wrote it, and the tool does not rewrite it. The text is not stored.
Add AI Text Check in Pi
Pi does not speak MCP on its own. The pi-mcp-adapter extension (these steps match version 2.34.0) loads remote servers and keeps their schemas out of the prompt until you ask. Install it once, then restart Pi:
pi install npm:pi-mcp-adapterAdd the server to a shared MCP file. Use .mcp.json in the project if only that project needs AI Text Check, or ~/.config/mcp/mcp.json if you want it in every project. Pi also reads ~/.agents/mcp.json. A Pi-only override lives in ~/.pi/agent/mcp.json or .pi/mcp.json and wins over the shared file.
{
"mcpServers": {
"ai-text": {
"url": "https://aitext.openkrill.app/mcp"
}
}
}The url is enough. Do not set command: that field is for a local process. No API key header. After restart, run /mcp and confirm the server is listed. The first call connects lazily. Ask: Which parts of this email sound like AI wrote them? The adapter should offer check_ai_writing.
Leave directTools off unless you want those schemas in every turn. With a handful of tools the cost is small. The default proxy is the better fit: search for the tool, then call it. /mcp disable ai-text writes a project override in .pi/mcp.json without editing the shared file. Run /reload after that change.
Pi will not find this server by scanning Cursor or Claude config unless you run /mcp setup and import it. Putting the url in .mcp.json is the direct path and the one this page tests against. The server is the same public endpoint the other clients use, with the same limits and the same privacy rules.
A call checked on 2026-10-01
A 59-word draft with stock openers is enough for a score. The tool uses fixed rules, stores nothing, and a score is not proof of who wrote the text. The request below was posted to https://aitext.openkrill.app/mcp as tools/call. HTTP 200. Source: the AI Text Check server, read 2026-10-01.
