Pyxmark tools (7)
write = sends, deletes, buys or postscheck_exclusionsFreeCheck a name against SAM.gov federal contracting exclusions (debarments/suspensions).
company_profileFreeFull SEC EDGAR record for one company, given its CIK, ticker or name (best match): legal name, industry (SIC), state of incorporation, business address, 3 fiscal years of revenue, net income, total assets and cash, and its recent 10-K, 10-Q and 8-K filings with links. Use search_company first if you only have a partial or ambiguous name.
domain_ageFreeDomain registration date, age, registrar (RDAP) and email-auth records (MX, SPF, DMARC), which are common fraud signals, plus first_archived: the date of the Wayback Machine's earliest snapshot (null if none; archive.status says unavailable if archive.org didn't answer). notes holds factual remarks, such as a first snapshot under 90 days old or a registration years older than the first snapshot; they are not flags.
due_diligence_reportFreeOne-call due-diligence report: SEC profile (if public), sanctions screen, federal exclusions, domain signals (registration age, email records, Wayback Machine first-seen date), and state registry link, with a red-flag summary, a verdict (clear / review / hold; rules at https://mcp.pyxmark.com/#verdict) and source links. An agent should not pay or onboard on 'hold', and should ask a person on 'review'. Informational only, not a compliance determination. Results come from public government lists and filings, may be incomplete or out of date, and fuzzy name matches can be false positives or miss variants. Verify every potential match against the official source before acting. Colorado vendors only (state CO or a Colorado address): address_density gives how many active Colorado companies list the vendor's address, from the Colorado Department of State's Business Entities in Colorado data (Public Domain), refreshed monthly. A building that also hosts a listed virtual mailbox service, an address shared by 1,000+ companies, or a registered agent's address used by hundreds of companies that almost none of them list as their principal address adds a worth-a-second-look line under info, never a red flag or a verdict change; other states are not covered.
screen_sanctionsFreeFuzzy-screen a person or organisation name against OFAC SDN + Consolidated, UN, EU, and UK sanctions lists. Returns up to 15 scored matches with source links; if more match, the summary says so and suggests a more specific query. Optional dob/birth_year, nationality and country set aside same-name matches whose listed details differ (rules at https://mcp.pyxmark.com/#details). Optional address, email, phone, website, ids and owners are matched against the details the lists give (identifier matches, sanctioned regions, the 50 percent rule); the assessment field sums it up as hold / review / clear. Informational only, not a compliance determination. Results come from public government lists and filings, may be incomplete or out of date, and fuzzy name matches can be false positives or miss variants. Verify every potential match against the official source before acting.
search_companyFreeLook up which SEC-registered company a name, ticker or CIK refers to. Returns up to 10 candidates, each with its CIK, tickers and a match score, and nothing else. Use it to pick the right CIK when a name is ambiguous, then call company_profile with that CIK for the details.
state_registry_linkFreeOfficial Secretary of State business-search link for a US state, to verify a private company's status, formation date, and registered agent.

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.

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/mcpChatGPT (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/mcpOr 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/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.
