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"

Tools

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.
