   %APPDATA%\Claude\claude_desktop_config.json
   

2. Add the following configuration to the mcpServers section:

   {
     "mcpServers": {
       "obsidian-mcp": {
         "command": "uv",
         "args": [
           "run",
           "python",
           "C:\\path\\to\\your\\obsidian-mcp\\main.py",
           "C:\\path\\to\\your\\obsidian\\vault"
         ]
       }
     }
   }
   

macOS/Linux Configuration

1. Open your Claude Desktop configuration file at:

   ~/Library/Application Support/Claude/claude_desktop_config.json  # macOS
   ~/.config/claude/claude_desktop_config.json                      # Linux
   

2. Add the following configuration to the mcpServers section:

   {
     "mcpServers": {
       "obsidian-mcp": {
         "command": "uv",
         "args": [
           "run",
           "python",
           "/path/to/your/obsidian-mcp/main.py",
           "/path/to/your/obsidian/vault"
         ]
       }
     }
   }
   

Alternative Configuration (without uv)

If you prefer not to use uv, you can configure it to run directly with Python:

{
  "mcpServers": {
    "obsidian-mcp": {
      "command": "python",
      "args": [
        "/path/to/your/obsidian-mcp/main.py",
        "/path/to/your/obsidian/vault"
      ]
    }
  }
}

Important Notes

• Replace /path/to/your/obsidian-mcp/main.py with the actual path to the main.py file
• Replace /path/to/your/obsidian/vault with the actual path to your Obsidian vault directory
• Use forward slashes (/) in paths even on Windows when using the JSON configuration
• Restart Claude Desktop after making configuration changes

Usage

Once configured, you can ask Claude to:

• "List all files in my Obsidian vault"
• "Show me the content of my daily note from yesterday"
• "Find all files related to 'project alpha'"
• "Search for all mentions of 'TODO' in my vault"
• "What notes do I have about machine learning?"

Claude will use the MCP server to access your vault and provide responses based on your actual notes and documents.
