Tells MCP

An MCP server that allows AI assistants to analyze text for writing habits that make it sound like a chatbot wrote it, score the text on a bot-o-meter, and mechanically fix easy issues like em dashes and filler words without uploading data.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Tells: Tells highlights the writing habits that make people think a chatbot wrote something, scores it from 0 to 100, and fixes the easy ones in one tap. Runs in your browser. Use it when you want your writing to sound less like a chatbot. Tools: tells_score_text (Score writing for AI-sounding habits); tells_fix_text (Remove the easy AI-sounding habits from writing). Result links such as open_url are safe to share with the user.

tells_score_text — Score writing for AI-sounding habits
Advertised by the server during the last successful anonymous check.
Advertised read-only

Checks a piece of writing for the habits that make people think a chatbot wrote it (em dashes, words like "delve", assistant filler like "I hope this helps", "it's not X, it's Y", fake suspense, stiff transitions, markdown leftovers, emoji bullets, rule of three, same-length sentences). Returns a 0-100 bot-o-meter score, a verdict and the tells found. Style habits only. Not an AI detector and not proof of who wrote the text.

tells_fix_text — Remove the easy AI-sounding habits from writing
Advertised by the server during the last successful anonymous check.
Advertised read-only

Rewrites the easy tells: swaps em dashes for commas, chatbot words for plain ones, strips assistant filler, markdown stars and emoji bullets, fixes stiff transitions. Habits that need a human rewrite ("it's not X, it's Y", fake suspense, rule of three) are listed but left alone. Returns the fixed text, the before and after score and what remains.

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http tells-mcp https://tells.clawhard.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add tells-mcp --url https://tells.clawhard.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable tells-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "tells-mcp": {
      "url": "https://tells.clawhard.com/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "tells-mcp": {
      "type": "streamableHttp",
      "url": "https://tells.clawhard.com/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start tells-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "tells-mcp": {
      "type": "http",
      "url": "https://tells.clawhard.com/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http tells-mcp https://tells.clawhard.com/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
Claude Desktop configuration

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
