Overview

Description from the maker (original English)

Vendor checks: sanctions lists, SEC filings, domain age and a due-diligence report with sources.

PopNx MCP’s three pillars

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

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

Common questions

Is Pyxmark 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 (0.1.0) reached the registry 19 days 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, HotCodePush

Pyxmark

Check a company before you pay it. Pyxmark is a hosted MCP server that screens a company or person against the OFAC, UN, EU and UK sanctions lists, looks the company up in SEC EDGAR, checks its web domain's age and email records, and puts it together in a due-diligence report with a clear, review or hold verdict. Every result links to the official record and says when each list was last synced.

  • Server: https://mcp.pyxmark.com/mcp (Streamable HTTP, no sign in or key)
  • Free, no account or key: 25 lookups a day per IP address
  • Docs: https://mcp.pyxmark.com/ · Methodology: https://pyxmark.com/methodology
  • Made by Trunnel & Co. · hello@pyxmark.com

This repository holds listing and install files only. The server is hosted; its code isn't published here.

Connect

Server URL: https://mcp.pyxmark.com/mcp (Streamable HTTP). No sign in and no key.

Claude (claude.ai and Claude Desktop): Customize → Connectors → + Add → Add custom connector. Name it Pyxmark, paste the server URL, choose No sign in, then Add. Free plans allow one custom connector. On Team and Enterprise an owner adds it first under Organization settings → Connectors.

Claude Code

claude mcp add --transport http pyxmark https://mcp.pyxmark.com/mcp

ChatGPT (web): Plugins → + → Add custom MCP server. Name it Pyxmark, paste the server URL, pick No authentication, select I understand and want to continue, then Create as a plugin. Install it and pick it with @ in a chat.

Codex and the ChatGPT desktop app

codex mcp add pyxmark --url https://mcp.pyxmark.com/mcp

Or in the desktop app: Settings → MCP servers → Add server, choose Streamable HTTP and paste the URL.

Cursor: use the Install in Cursor button, or add this to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (one project):

{ "mcpServers": { "pyxmark": { "url": "https://mcp.pyxmark.com/mcp" } } }

VS Code (GitHub Copilot): use the Install in VS Code button, or run MCP: Add Server from the Command Palette, choose HTTP and paste the URL. From a terminal:

code --add-mcp '{"name":"pyxmark","type":"http","url":"https://mcp.pyxmark.com/mcp"}'

Grok: at grok.com/connectors choose New Connector, then Custom, and paste the URL. On Grok Business and Enterprise a team admin adds it first. In Grok Build:

grok mcp add --transport http pyxmark https://mcp.pyxmark.com/mcp

Grok Bot: there's no settings form. Tell your bot "Add this MCP server: https://mcp.pyxmark.com/mcp". It confirms, and the tools work from your next message.

Gemini CLI

gemini mcp add --transport http -s user pyxmark https://mcp.pyxmark.com/mcp

Other clients: most read the standard block below, which is also this repo's .mcp.json (Claude Code, VS Code and Grok Build pick it up from a project root). Clients that only run local stdio servers can use npx -y mcp-remote https://mcp.pyxmark.com/mcp.

{ "mcpServers": { "pyxmark": { "type": "http", "url": "https://mcp.pyxmark.com/mcp" } } }

Check it works: ask "List the Pyxmark tools". You should see 7 read-only tools. Then ask "Is Microsoft Corporation on any sanctions list?" It should come back with no match.

AI agents setting this up for a user: follow llms-install.md.

Tools

Six tools are listed today, all read-only. A seventh, check_exclusions (SAM.gov federal exclusions), is added to the list once SAM.gov data has synced; until then each due_diligence_report includes a link to search SAM.gov yourself.

ToolWhat it does
due_diligence_reportOne report on a vendor: sanctions screen, SEC record and risk filings, domain age, first Wayback Machine snapshot and email records, ending in a clear, review or hold verdict with reasons
screen_sanctionsFuzzy-screens a name against OFAC SDN and Consolidated, UN, EU and UK lists. Optional birth date, nationality and country tell apart people with the same name. Optional address, email, phone, website, IDs and owners are matched against what the lists record, including sanctioned regions and the OFAC 50 percent rule
search_companyFinds which SEC-registered company a name, ticker or CIK refers to
company_profileThe SEC EDGAR record for one company: identity, address, three years of key financials and recent filings
domain_ageDomain registration date and registrar (RDAP, with a WHOIS fallback), its MX, SPF and DMARC records, and the date of its first Wayback Machine snapshot
state_registry_linkA link to the US state business registry search for a company

Try asking

  • "Run a due diligence report on Acme Corp, acme.com, Delaware."
  • "Is this supplier on any sanctions list?"
  • "Show me Tesla's last three years of revenue and recent 8-Ks."

Results are informational, not a compliance determination. Names are matched fuzzily, so check any potential match against the linked official entry before you act. Pyxmark isn't for consumer screening (credit, jobs, housing, insurance or tenancy).
