Why MCP

  • Agent-native — Tools are discovered automatically when your client connects; no manual endpoint wiring.
  • Scoped to you — Every request runs as the authenticated user with license and access checks.
  • Risk-aware — Each tool is labeled read, write, or destructive so clients can require confirmation before side effects.
