# An AI gateway for agents, models, and MCP servers

  
    
    Point your apps at one endpoint that speaks both the OpenAI and Anthropic APIs, and your agents at one MCP endpoint. Route to any model, fail over automatically, enforce rate limits and guardrails, track spend against budgets, and attribute spend by team and agent. Control which MCP tools each agent can reach, and manage policies centrally across a fleet of AI gateways. Provider-neutral, from a quick trial through enterprise rollout.

## Choosing the right Agent Router product {#which-is-right-for-you}

This table compares Agent Router Service with Agent Router Enterprise. Within Enterprise, Fully Managed and Self-Hosted Data Plane share the same features and differ only in where the data plane runs: Fully Managed is hosted end to end by Tetrate; Self-Hosted Data Plane keeps AI traffic on your infrastructure while Tetrate still hosts the management plane.
