# AI Rule Engine > AI Rule Engine turns your business logic into governed, auditable AI workflows, then lets AI agents like Claude, Cursor, and ChatGPT trigger them through the Model Context Protocol (MCP) with the exact permissions you grant. Multi-model AI (Anthropic, OpenAI, Google) and human-in-the-loop approval are built in. AI Rule Engine is a cloud platform for teams that want AI agents to take real actions safely. You define rules, workflows, and tools once; AI agents call them as MCP tools scoped to the permissions you set; every run is logged and auditable, with optional human approval gates. It runs on Azure and works with Anthropic, OpenAI, and Google models. ## Core pages - [Home](https://www.ruleengine.ai/): Product overview — governed workflows and tools that AI agents trigger through MCP. - [Pricing](https://www.ruleengine.ai/pricing/): Free, Pro ($49/mo), Team ($199/mo), and Enterprise ($999/mo) plans, plus add-on packages and a Custom tier.
