An open-source gateway that fronts model providers and Model Context Protocol (MCP) servers with access control by token scopes, claims, tool and CEL rules, or an external authorization service.
Where it sits
3.3 Gateways (primary): Sits on the request path between agents and their models, MCP tools and other agents, and allows or denies tool calls by token scopes, claims, tool names and CEL rules, or by an external authorization service.
Your agent gets one OpenAI-compatible API for every model and one router for every MCP tool.
