Turns Obsidian vaults into AI-queryable knowledge graphs with 12 tools

io.github.seynurmammad0v/obsidian-mcp โ€” MCP Server for Obsidian Knowledge Graphs

This MCP server turns any Obsidian vault into an AI-queryable knowledge graph using 12 tools. It uses a graph-first approach (BFS, shortest path, connected components, and bridge detection via [[wikilinks]]). It supports vault-agnostic operation with zero required infrastructure (no database, no running Obsidian, no API keys).

๐Ÿ› ๏ธ Key Features

  • Graph algorithms: BFS, shortest path, connected components
  • Bridge detection via [[wikilinks]]
  • Backlink-aware writes: move_note updates references across the vault
  • Vault-agnostic: works with any existing vault (no required structure)
  • Lightweight: 4 runtime dependencies, ~42KB bundle
  • 12 tools

๐Ÿš€ Use Cases

  • Query an Obsidian vault as a knowledge graph
  • Analyze relationships and connectivity between notes
  • Find graph bridges based on [[wikilinks]]
  • Move notes while automatically updating backlinks

โšก Developer Benefits

  • No database setup; no Obsidian instance needed
  • No API keys required
  • Works with existing vault content without restructuring
