FastMCP server for surgical queries against a vault knowledge graph (NetworkX no
If you've built a knowledge graph from your Obsidian vault using NetworkX, this server lets Claude query it surgically instead of dumping 50K lines of graph data into context every time. It loads your graph.json once at startup and exposes seven tools: fuzzy node search, neighbor traversal with configurable hop depth, shortest path finding, degree-ranked top nodes, subgraph extraction around concept clusters, detailed node metadata, and community detection lookups. Supports dual graphs if you maintain separate personal and team vaults. Pairs naturally with the graphify skill from ai-brain-starter, though any NetworkX node-link JSON works. Query latency under 50ms, all in-memory, no external services.
