Smarter MCP Servers: Using a Graph to Solve the Context Window Problem

Session Track: Graph + AI in Production

Session Time: 11:30 am - 12:00 pm April 15

Session description

Every tool you register in an MCP server costs tokens — before a single prompt runs. When you have multiple tools, that overhead is real. This session compares three architectural patterns for managing tool discovery in MCP servers, from simple lazy-loading to a graph-backed registry that surfaces the most relevant tools first and gets smarter with every call. Using Neo4j Aura as the concrete example, we’ll show how storing your tool list as a graph — with usage weights, co-occurrence edges, and category relationships — turns a flat list into an adaptive, self-improving capability layer.
