Connects Claude Desktop to an Obsidian vault, enabling reading, searching, capturing ideas, and managing notes through natural language.

README

Obsidian Brainstorm

Connect Claude to your Obsidian vault. Read notes, search your knowledge graph, capture ideas to your daily note, explore backlinks, filter by tags, and more — all from Claude Desktop.

Quickstart

Add this to your claude_desktop_config.json (replace the path with your vault):

{
  "mcpServers": {
    "obsidian-brainstorm": {
      "command": "npx",
      "args": ["-y", "obsidian-brainstorm"],
      "env": {
        "OBSIDIAN_VAULT_PATH": "C:/Users/you/Documents/MyVault"
      }
    }
  }
}

Restart Claude Desktop. That's it — no installation required.

Windows users (non-technical): double-click setup.ps1 for a graphical setup wizard with a folder picker and multi-vault manager.

What you can do

Ask Claude things like:

"List my recent notes from the last 3 days"
"Search my vault for anything about machine learning"
"What notes link to my 'Project Alpha' note?"
"Add this to today's daily note: remember to call Alice"
"Show me all notes tagged #project"
"Create a new note in Ideas/ about..."
"Give me stats on my vault"

Resources

Notes are also exposed as MCP Resources (obsidian-brainstorm://VaultName/path/to/note.md), letting MCP clients browse your vault like a file explorer.

Multi-vault

Store multiple vaults in %APPDATA%/obsidian-brainstorm/config.json and switch between them with switch_vault. The OBSIDIAN_VAULT_PATH environment variable always takes priority, making it easy to point different Claude projects at different vaults.
