About
What is Preloop?
Preloop is a robust policy engine designed for AI agents, providing a critical safety layer for automated operations. It enables users to define granular policies, specifying which AI actions are allowed, denied, or require human approval based on context. This platform ensures full visibility and an audit trail for every AI operation, logging all tool calls with comprehensive context. Preloop integrates seamlessly with MCP-compatible AI agents like Claude Code, Cursor, and Windsurf, requiring no SDK or code changes. When an AI agent attempts an action needing approval, Preloop instantly notifies users via mobile, Slack, Mattermost, or email, allowing for approval or rejection from anywhere. This prevents costly mistakes like accidental code deployments or database deletions, providing essential guardrails for AI agent deployment in production environments.

FAQs
Which AI agents does Preloop support?
Preloop works with any MCP-compatible AI agent, including popular ones like Claude Code, Cursor, Cline, and Windsurf. Setup is designed to be quick and straightforward, typically taking about 3 minutes to connect your agent.
How does Preloop handle actions requiring human approval?
When an AI agent attempts an action that requires approval, Preloop sends instant notifications via mobile app, Slack, Mattermost, or email. You can then approve or reject the action from any of these platforms, and the AI agent will wait for your decision.
Will using Preloop slow down my AI agents?
Only actions that explicitly require human approval will pause for your input. Allowed actions run instantly without delay, and denied actions fail immediately with a clear message. Most workflows proceed without any noticeable slowdown.
