Why 0nMCP?

• One server, every API. No juggling 20 integrations. One MCP server handles it all.
• • Natural language. Say "Invoice john@acme.com for $500 and notify #sales on Slack" — it happens.
  • • Patent-pending security. 0nVault encrypted containers with zero-knowledge credential proxying.

    • • Production ready. Rate limiting, webhooks, HMAC verification, CLI tooling, and Docker support.

      • • 1,466 tools across 101 services — the largest MCP tool catalog available.
