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

scan

scan_draft

Scan a draft for the patterns that make writing read as AI-generated: banned vocabulary, structural tells (triplets, negation formulas, summary closers, colon chains, flat rhythm), and pattern density scored against the accumulation threshold. Deterministic — the same text always returns the same findings. Run this before showing the user any outward-facing draft: an email, a post, a cover letter, marketing copy, a blog article. Returns each finding with the evidence quoted from the text and the fix.

Prose Coach — questions

Answers built from our own checks of this server.

What can Prose Coach do?

It exposes 1 tools, read directly from the server on our last check. Among them: scan_draft. 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 Prose Coach 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 1129 ms. The bar chart above shows every period we have measured.

How do I connect Prose Coach?

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 Prose Coach need an API key?

No. Prose Coach 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 Prose Coach?

It answers our handshake in 1129 ms on average, which is faster than 4% 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.
