Obsidian MCP

Exposes 12 tools that treat your Obsidian vault as a queryable graph, no Obsidian app or database required. Read and search notes with tag and frontmatter filtering, traverse the wikilink graph with BFS/DFS, find shortest paths between notes, and detect connected components or bridge nodes. Write operations include creating notes, patching sections, and moving files with automatic backlink updates across the entire vault. Scans your vault once on startup to build an in-memory graph, then watches for changes incrementally. Reach for this when you want Claude to navigate and manipulate your existing Obsidian knowledge base as a first-class graph structure rather than flat markdown files.
