A commercial gateway (formerly Portkey) that proxies model and Model Context Protocol (MCP) traffic, with guardrail checks, tool provisioning and webhook guardrails that call out to an operator's own service.
Where it sits
3.3 Gateways (primary): Sits on the request path between applications and their models, and between MCP clients and MCP servers, and can deny a call when a guardrail check fails or a tool is not provisioned to the caller.
It acts as a proxy between MCP Clients and MCP servers, handling authentication, access control, and logging.
