Argorant MCP

Verified B2B contact data for AI agents. Search, count, preview, reveal, export, and build saved lists across 600M+ business contacts — directly from Claude, ChatGPT, Cursor, and any MCP client.

• MCP endpoint: https://mcp.argorant.com/mcp

• Transport: Streamable HTTP · Auth: OAuth 2.1 (Dynamic Client Registration, account-scoped)

• Website: https://argorant.com · Privacy: https://argorant.com/privacy · Terms: https://argorant.com/terms

This is a hosted remote connector — no install, no API key paste. Clients connect to the endpoint and authenticate via OAuth. A standalone CLI also exists (npx argorant) for terminal/script use.

Connect

Claude (claude.ai / Desktop): Settings → Connectors → Add custom connector → URL https://mcp.argorant.com/mcp → complete the OAuth login.

ChatGPT (Developer Mode): Settings → Apps & Connectors → Advanced → enable Developer Mode → Connectors → Create → URL https://mcp.argorant.com/mcp. The search + fetch tools make it usable as a Deep Research connector.

Cursor / other MCP clients: add the remote server from mcp.json:

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

Tools

Free (no credits, masked/aggregate only):

Consume credits (require OAuth scope + permission; verification is live at this step and only valid/deliverable contacts are billed):

Tools are annotated with read-only vs. action hints. Reveal/export/list actions only run after OAuth, scope, permission, quota, and plan checks; without credits they are blocked by design.

Data & privacy posture

• OAuth + account-scoped. Unauthenticated requests to /mcp return 401 with WWW-Authenticate pointing at protected-resource metadata.

• Masked by default. search/fetch/preview never return raw emails, phones, or profile URLs — only aggregate coverage and masked rows. Raw contact details require the scoped reveal/export tools and consume credits.

• Verification is live. Emails are verified at reveal/export time; you are billed only for deliverable contacts. Raw verification status is never exposed as a queryable field.

• Hosts are separated: argorant.com (marketing/docs), app.argorant.com (signed-in app), mcp.argorant.com (remote MCP + OAuth).
