Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@TwoThumbs MCP verify that the contact form at example.com actually submits"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
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.
The server speaks Streamable HTTP at:
https://twothumbs.co/mcpNo local install, no package, no API key required to use the anonymous tools.
claude mcp add --transport http twothumbs https://twothumbs.co/mcpOr 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-mcpAdd to your MCP settings (Cursor Settings → MCP):
{
"mcpServers": {
"twothumbs": {
"url": "https://twothumbs.co/mcp"
}
}
}{
"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.
