Report #86601

[frontier] Agent needs tools from multiple MCP servers but managing separate connections is complex and context-inefficient

Use an MCP gateway or proxy that aggregates multiple MCP servers behind a single connection. The client connects to one gateway; the gateway fans out to multiple servers, merges tool lists, and routes calls. This reduces client complexity and lets you manage server lifecycle independently.

Journey Context:
As the MCP ecosystem grows, agents need tools from many servers: filesystem, GitHub, database, search, etc. Connecting to each separately means multiple transport configs, separate auth, N tool lists consuming context, and no cross-server tool composition. The gateway pattern \(emerging in MCP community implementations\) solves this: one connection, merged tool namespace, unified auth, and the gateway can even implement cross-server workflows \(e.g., read file from filesystem server, search for similar code in vector DB server\). Tradeoff: the gateway is a new infra component to deploy and maintain. It also becomes a single point of failure without redundancy. Start with a simple proxy for development, add production hardening as you scale.
