Overview

Description from the maker (original English)

Voice-style checks and a deterministic AI-tell audit for your writing.

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on your computer with your user’s permissions (files, network, apps).
The registry lists no key to fill in.

You need

npmNode.js installed (for the npx command)

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "tellcheck": {
      "command": "npx",
      "args": [
        "-y",
        "@reneturcios/tellcheck",
        "mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add tellcheck -- npx -y @reneturcios/tellcheck mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "tellcheck": {
      "command": "npx",
      "args": [
        "-y",
        "@reneturcios/tellcheck",
        "mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "tellcheck": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@reneturcios/tellcheck",
        "mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Tellcheck safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 4 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js, Docker on your computer.

What can I use instead?

tellcheck

Check a piece of writing against a voice style, and scan it for the tells that make prose read as machine-generated. Everything runs locally and deterministically: no network, no API key, no model calls. State (styles, dictionaries, instructions, default style) persists as JSON under TELLCHECK_HOME or ~/.tellcheck.

This is a clean-room rebuild of the etincel writing-style tool, implemented from its public README tool spec. Schemas are documented reconstructions from that prose.

What it does

Styles. Twelve shipped presets (Direct & Warm, Executive Brief, Reflective Essayist, Founder Memo, Plainspoken Analyst, Wry & Candid, PR Review, Code Comment, Slack Message, LinkedIn Post, Website Copy, Blog Post), each with formality / warmth / directness dials and a rhythm description. Train your own style from samples, create one directly from dials, fork, update, delete, and set a default.
Voice match. Compare a draft's rhythm and mechanics (sentence length and variance, contraction rate, em-dash use, fragments, questions) against a style baseline. Short input gets an honest low-confidence note instead of a false-precision score.
Self-repetition. Repeated sentence openers and phrases, including repetition against a trained style's own samples.
AI-tell audit. A deterministic scan: a built-in tell vocabulary with a suggested replacement for each hit (for example "comprehensive", "cutting-edge", "leverage", "seamless", "streamline"), rhythm findings (uniform paragraph length, low burstiness), and strengths (specificity, concrete-to-abstract balance). Returns a tier — green, yellow, orange, or red — plus a 0–100 score and findings with locations. Registers: email, blog, memo, essay, social, docs, general, personal; the docs register suppresses markdown-structure findings. Supplying sourceFacts flags numbers in the text that the facts do not back.
Dictionaries and instructions. Global and per-style banned-word and custom-word lists, plus free-form style instructions.
second_read, honestly. In the original, the local install's second read always fails with a clear explanation (the feature needs a hosted model). This rebuild reproduces exactly that behaviour rather than faking a result.

CLI

One subcommand per tool, taking a single JSON argument object:

npx @reneturcios/tellcheck list_styles '{}'

npx @reneturcios/tellcheck get_style_guide '{"styleId":"founder-memo"}' npx @reneturcios/tellcheck train_style '{"name":"My Voice","samples":["..."]}' npx @reneturcios/tellcheck audit_text '{"text":"...","register":"blog"}' npx @reneturcios/tellcheck --version

Exit codes: 0 success, 1 tool error, 2 usage error.

MCP

npx -y @reneturcios/tellcheck mcp

MCP client config:

"mcpServers": { "tellcheck": { "command": "npx", "args": ["-y", "@reneturcios/tellcheck", "mcp"] } } }
