Nanostores MCP
Connects Claude to your Nanostores state management layer with both static and runtime analysis. On the static side, it walks your AST to map out atoms, maps, computed stores, and their dependency graphs across React, Vue, Svelte, and Angular codebases. For live debugging, it bridges @nanostores/logger events over HTTP to surface mount/unmount cycles, value changes, and action timing in real time. You also get full-text search against the official Nanostores docs. Useful when you need to diagnose why a store is updating too often, trace which components subscribe to what, or generate architecture diagrams without manually grepping imports.
