Preloop: The Safety Layer for AI Agents

AI agents can deploy code, delete databases, and manage infrastructure. Preloop keeps you in control—approve risky actions before they execute.

Know exactly what AI is doing

Connect Claude Code, Cursor, or Windsurf to Preloop. Every tool call is visible—see what your AI agents are doing in real-time. No SDK, no code changes.

Approve before AI acts

Dangerous operations pause for human approval. One-tap approvals from your phone, Slack, or email—reject with a reason so AI can try a safer approach.

Stay in control, move fast

AI handles routine work instantly. Only risky operations (deploys, deletes, billing changes) need your approval—so you keep velocity while preventing costly mistakes.

What is Preloop?

Preloop is the safety layer for AI agents. It intercepts risky operations before they execute, lets you approve or reject with one tap, and maintains a complete audit trail of every AI action.

Why do I need a safety layer for AI agents?

AI agents can now deploy code, delete databases, spin up expensive cloud resources, and manage infrastructure. One mistake can cost hours of downtime or thousands of dollars. Preloop catches dangerous operations before they happen.

How does it work?

Connect your AI coding assistant (Claude Code, Cursor, Windsurf) to Preloop. When AI tries something risky—like a production deploy or database deletion—you get an instant notification. Approve with one tap, or reject with a reason.

What kinds of actions can I protect?

Any operation exposed via MCP: deployments, database changes, billing modifications, secret management, and more. You define what's risky for your environment.

Which AI assistants does Preloop support?

Preloop works with any MCP-compatible AI assistant, including Claude Code, Cursor, and Windsurf. Setup takes 3 minutes.

How do I get approval notifications?

Preloop sends notifications via mobile app, Slack, Mattermost, or email. Approve or reject from anywhere—your phone, your Slack channel, or the Preloop dashboard.

Will this slow down my AI agents?

Only risky operations pause for approval. Safe operations (reading files, searching, generating reports) run instantly. You stay fast on routine work while staying safe on critical actions.

What happens when I reject an action?

The AI agent receives your rejection with an optional reason. It can then stop, ask you for guidance, or try a safer alternative approach.

Do I get an audit trail?

Yes. Every AI action is logged—what was attempted, who approved or rejected it, and when. Perfect for security reviews and understanding what your AI agents are doing.
