CTRLRun is an open-source execution-safety layer for consequential AI-agent actions such as refunds, payments, deletes, emails, deployments, and other operations you do not want an agent executing incorrectly or twice.Wrap a function with @protect and define a small YAML policy. CTRLRun then controls whether the action can execute.It provides:<ul><li>Exact approval binding: approval for €2,000 cannot be reused for €5,000.</li><li>Duplicate-effect protection: retries cannot blindly execute the same consequential effect twice.</li><li>Ambiguous outcome handling: if the external action may have succeeded but the response was lost, CTRLRun treats it as AMBIGUOUS, not FAILED.</li><li>Runtime policy enforcement: low-risk actions can execute automatically, higher-risk actions can require approval, and prohibited actions are denied.</li><li>Execution receipts: every executed action leaves a record of what was authorized, what ran, and how it ended.</li></ul>CTRLRun works with plain Python, LangGraph, OpenAI Agents SDK, and MCP servers through its gateway.Try it locally:pip install ctrlrun &amp;&amp; ctrlrun demoThe demo runs five common agent-execution failure scenarios and shows how CTRLRun handles each one. It runs offline in under a second.Core dependencies are intentionally small. State can use SQLite or PostgreSQL.Apache-2.0 licensed.
