An MCP proxy serves as an intermediary, connecting AI clients to upstream MCP servers by acting as both an MCP server and client. This setup is particularly useful for bridging different communication transports, such as stdio and Streamable HTTP, and for consolidating multiple tool-hosting MCP servers under a single endpoint. The proxy handles tool discovery and invocation, relaying requests and responses between clients and servers while managing security risks like confused deputy attacks and credential handling. Bifrost, an open-source AI gateway developed by Maxim AI, functions as an MCP gateway, offering these proxy capabilities along with additional governance features. AI
IMPACT Standardizes communication between AI clients and tool-hosting servers, enabling more complex agent architectures.
