Overview
Description from the maker (original English)
Verifies AI agent work end to end: real artifacts and outcomes checked, not self-reported success.
PopNx MCP’s three pillars
These three are never merged into one score: opinions, measurements and popularity are different things.

Common questions
Is Twothumbs 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 in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 3 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Spec Driven Development, Remote Desktop Commander, Python MCP

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/mcpNo local install, no package, no API key required to use the anonymous tools.
Claude Code
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-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.
