# Agent Sentinel > The Runtime Authority for AI Agents. Decide what your agents are allowed to do—before they do it. ## What it is - Budget enforcement that caps spend per action, run, or session to prevent runaway LLM costs. - Action deny lists that block irreversible or dangerous operations before they execute. - Approval workflows and human intervention registries that keep a human in the loop. - An immutable, audit-ready ledger of every decision, input, and policy check for compliance (including EU AI Act Article 14). - A Python SDK (`agentsentinel-sdk`) that deploys with an agent stack in minutes. ## Docs - [Agent Sentinel](https://agentsentinel.dev): marketing site and product overview. - [Documentation](https://docs.agentsentinel.dev): integration guides and API reference. - [Console](https://console.agentsentinel.dev): policy, budget, and approval management. - [API](https://api.agentsentinel.dev): the runtime platform the SDK talks to. - [PyPI package](https://pypi.org/project/agentsentinel-sdk): `pip install agentsentinel-sdk`. ## Contact - Security: see https://agentsentinel.dev/.well-known/security.txt
