Sanctions screening, KYB, identifier validation, jurisdiction risk & secret scanning for AI agents

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

Common questions

Is Sanctions Screening safe?

It passed 0 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 (1.1.0) reached the registry 4 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, zanadir

Watchtower — Compliance & Data-Integrity MCP Server for AI Agents

Live hosted MCP endpoint: https://watchtower-api.com/mcp · Docs: https://watchtower-api.com/docs · OpenAPI: https://watchtower-api.com/openapi.json

Watchtower is a deterministic compliance & data-integrity API for AI agents. Point any MCP client at the hosted endpoint and your agent gets tools for sanctions screening, KYB, identifier validation, jurisdiction risk, PII/secret detection, and LEI resolution — pay per call with x402 (USDC on Base, no signup) or a prepaid API key.

This repo is the public home for the hosted Watchtower MCP server. There's nothing to install — connect to the remote endpoint below.

Connect

{

"mcpServers": { "watchtower": { "url": "https://watchtower-api.com/mcp" } } }

Streamable-HTTP MCP, stateless — no auth handshake. Paid tools take an api_key argument (create one for free with the create_api_key tool, which includes trial credit) or you can pay per call via x402.

Why Watchtower

  • Deterministic & auditable — same query + same list snapshot ⇒ byte-identical result, stamped with a content-hash and algorithm version, plus point-in-time (as_of) screening for "what did the list say when we onboarded them?"
  • Broad, authoritative coverage — 10 official government lists, ~229,000 parties, refreshed daily.
  • Built for agents — pay-per-call via x402 (USDC on Base, no account) or MCP; no minimums, no seats.

Also available as REST + x402

Everything above is also a REST API. Pay per call in USDC via x402 with no signup:

import { wrapFetchWithPayment, x402Client } from '@x402/fetch';

import { ExactEvmScheme } from '@x402/evm'; const pay = wrapFetchWithPayment(fetch, new x402Client().register('eip155:8453', new ExactEvmScheme(signer))); await pay('https://watchtower-api.com/v1/screen', { method: 'POST', headers: { 'content-type': 'application/json' }, body: JSON.stringify({ name: 'Vladimir Putin' }) });
