MCP Dev Summit Bengaluru 2026

Most retrieval systems ignore the structure MCP Resources already provide unique URIs, typed links, version metadata, timestamps and flatten everything into vector chunks. GraphRAG proved retrieval needs relational structure; MCP already has it natively.
This talk demonstrates with a live adversarial demo: a vanilla RAG agent and a Resource-graph agent answer the same questions against the same corpus. RAG works on single-hop queries. It confidently returns stale data when a superseded document exists. The graph agent catches the version conflict using last-modified metadata that was already there. When the graph has a broken link, it reports the dead end instead of hallucinating.
A hop-count benchmark across seven questions (1–5 hops) makes the gap measurable: at three hops, RAG hit rate dropped to 50% while graph traversal held at 100%.
The primary deliverable is a draft cross-reference metadata convention four optional fields (superseded_by, depends_on, implements, compliance_scope) that any MCP Resource provider can add without breaking existing consumers. The goal: make knowledge as navigable for AI agents as hypertext made the web for people.
