As MCP adoption scales beyond a single server, context bloat becomes a critical bottleneck. When agents operate across multiple MCP servers — each exposing dozens of tools — injecting every available tool into the model context inflates the context window, increases latency, raises costs, and degrades reasoning quality. Most current implementations have no answer for this.
This session introduces the MCP Gateway pattern: a semantic routing layer that sits between the agent and its MCP servers. Rather than flooding the model with every registered tool, the gateway dynamically selects and injects only the tools relevant to the current request — using intent classification, embedding-based search, and prompt analysis.
We'll cover why context bloat is a natural byproduct of multi-server deployments, how semantic routing maintains full MCP protocol correctness, and how just-in-time tool discovery keeps the agent loop efficient. Attendees leave with a practical, vendor-neutral blueprint for scaling agentic systems to hundreds of tools without sacrificing performance or reasoning quality.
