"Search my Obsidian vault for notes mentioning 'pricing' and list the top 5"
- ! The server reads and writes files directly — back up your vault before heavy automation
- ! File path encoding and special characters in note names can cause edge cases
- ! Large vaults (10k+ notes) may take time to search — scope queries by folder when possible
API key or simple config
// When to use
- You use Obsidian as your knowledge base and want AI to help navigate it
- You want to capture new notes from conversation without context-switching
- You're building a second-brain workflow with AI-assisted synthesis
- You need to search across a large vault by topic, tag, or link
// When NOT to use
- You use Notion, Roam, or a cloud-only notes app (use notion-mcp for Notion)
- Your vault is in iCloud on a path the MCP can't reach reliably
- You need heavy plugin integration — the server can't execute Obsidian plugins

// About
Plain English
Imagine asking your AI: 'Find my notes about that product launch idea' or 'Create a daily note with today's tasks' — and it reads and writes your Obsidian vault directly. This server connects your AI to your local Obsidian vault so it can search, read, create, and update markdown notes.
The Obsidian MCP server connects AI assistants to your Obsidian vault. Read and write notes, search across your knowledge base, follow links between notes, and leverage your personal knowledge graph through conversation.
Ideal for researchers, writers, and knowledge workers who use Obsidian as their second brain and want AI to interact with their notes.
// Use Cases
- Search and retrieve notes from your Obsidian vault
- Create new notes and summaries through AI
