Agent Router: MCP vendor profile
Agent Router, the renamed Envoy AI Gateway, is an open-source Envoy-based router that gives agents one OpenAI-compatible API for models and an MCPRoute gateway that aggregates and filters MCP servers, as documented by the vendor. The Agent Router repository says nothing deployed is renamed by the move to the Agentic AI Foundation, with the same release cadence (github.com).

What it does for this layer
The github.com/envoyproxy/ai-gateway URL redirected to github.com/theagentrouter/agent-router on 5 Nov 2026; the repository keeps the Apache 2.0 license and had about 2.4k stars (github.com, observed 5 November 2026). Agent Router configures MCP routing through an MCPRoute resource (apiVersion aigateway.envoyproxy.io/v1beta1), with a worked example that proxies the GitHub MCP server (aigateway.envoyproxy.io). Agent Router states "Complete June 2025 MCP spec compliance", including tool calls, notifications, prompts, resources and server-to-client requests (aigateway.envoyproxy.io).
Agent Router supports Streamable HTTP for MCP and enforces OAuth authentication flows natively, per its MCP capability page (aigateway.envoyproxy.io). The Agent Router docs were at version 1.2 on 5 Nov 2026, with an Agent Router CLI listed in the docs (aigateway.envoyproxy.io). The Agent Router site says it was "Formerly Envoy AI Gateway" and is "now an Agentic AI Foundation project", with the same code and maintainers (aigateway.envoyproxy.io).
The Agent Router MCP gateway aggregates several MCP servers into one endpoint, filters which tools clients see, and injects upstream API keys (aigateway.envoyproxy.io).

What it does not do
- Agent Router does not host MCP server code; it routes to backends that run elsewhere.
