TwoThumbs MCP

Verify what your AI agent actually did — not what it says it did.

TwoThumbs is a hosted, remote MCP server built by NOMOI Labs. It engineers an evidence-backed prompt, challenges weak premises, then checks the real artifact and downstream outcome a public web surface actually produced — instead of trusting a self-reported "success" message. It also carries a much larger internal prompt-engineering and verification-lifecycle tool set (51 tools total), of which the 3 tools below are exposed publicly over the hosted HTTP endpoint.

This repository is a thin discovery wrapper: an MCP client config, a Claude Code plugin manifest, and this README. There is no source code to install or build — the server itself is hosted and run by NOMOI at twothumbs.co.

Connect

The server speaks Streamable HTTP at:

https://twothumbs.co/mcp

No local install, no package, no API key required to use the anonymous tools.

Claude Code

claude mcp add --transport http twothumbs https://twothumbs.co/mcp

Or install this repository as a Claude Code plugin (adds the same server via .mcp.json):

/plugin marketplace add asselwan/twothumbs-mcp
/plugin install twothumbs@twothumbs-mcp

Cursor

Add to your MCP settings (Cursor Settings → MCP):

{
  "mcpServers": {
    "twothumbs": {
      "url": "https://twothumbs.co/mcp"
    }
  }
}

Generic MCP client

{
  "mcpServers": {
    "twothumbs": {
      "type": "http",
      "url": "https://twothumbs.co/mcp"
    }
  }
}

Works with any client that supports the Streamable HTTP transport — Claude Code, Cursor, Codex, and CI/headless clients included.
