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.

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/mcpGrok 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/mcpOther 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.

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.
Tool | What it does |
| One 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 |
| Fuzzy-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 |
| Finds which SEC-registered company a name, ticker or CIK refers to |
| The SEC EDGAR record for one company: identity, address, three years of key financials and recent filings |
| Domain registration date and registrar (RDAP, with a WHOIS fallback), its MX, SPF and DMARC records, and the date of its first Wayback Machine snapshot |
| A link to the US state business registry search for a company |
"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).
