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.
Tools
Available anonymously, with a free daily quota:
| Tool | What it does |
|---|---|
run_verdict | Exercises every visible affordance on a public URL — clicking, submitting forms with clearly marked synthetic data — then returns a pass/fail verdict grounded in the real downstream outcome, not a self-reported success message. |
list_surfaces | Lists the target surfaces currently configured for run_verdict. |
redeem_code | Exchanges an access code for an API key. |
An API key additionally unlocks get_last_verdict, get_balance, and set_auto_topup.
Pricing
- Free — 3 surface scans/day, no signup required.
- $9 — 100 credits.
- $29 — 500 credits.
Billing is invoice-based; email through twothumbs.co to request a key, or
use redeem_code with an access code.
