Works with every MCP server
AI agents are powerful. Unchecked, they're dangerous.
Without Sift
- ✗ Agents can delete files, drop tables, leak secrets
- ✗ No visibility into what tools are being called
- ✗ Each MCP server is a separate attack surface
- ✗ No way to enforce policies across your team
With Sift
- ✓ Dangerous operations blocked before they execute
- ✓ Complete audit trail of every tool call
- ✓ Single security layer across all servers
- ✓ Centralized policies for your entire org
