About ctrlrun
ctrlrun is a Python library that intercepts AI agent actions before they execute, validating them against user-defined policies. It normalizes diverse agent outputs into a single action type, checks each action against configured rules, and enforces outcomes based on those rules. Actions are either allowed to proceed, held for human approval, or blocked entirely. The system records a receipt for every executed action, ensuring idempotency and preventing duplicate or modified executions. It supports both SQLite for single-host deployments and Postgres for distributed environments. The library integrates with various AI agents and frameworks, including LangChain, LangGraph, OpenAI Agents SDK, and MCP, by wrapping the consequential function calls and applying policy rules via YAML configuration. It is designed to prevent wrong, restricted, or malicious actions in workflows where AI agents interact with critical systems.

- Blocking accidental deletion of critical records
- Enforcing approval workflows for infrastructure changes
Pros
- Intercepts actions before execution to prevent irreversible changes
- Supports both human approval and autonomous decision-making based on rules
- Records receipts for all actions to ensure idempotency and auditability
- Works with agents that can and cannot be modified
- Provides production-grade deployment options with SQLite or Postgres
Cons
- Requires Python environment for integration
- No explicit support for non-Python agents without adapters
- Policy configuration requires manual setup via YAML
