Obsidian Sync MCP

Give any AI agent access to your Obsidian vault over MCP. Run it locally against your vault files, or pair it with Self-hosted LiveSync and deploy to the cloud so it works even when your machine is off. Its 9 documented tools cluster into read & search, update, create & write, delete.

People connecting productivity tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

Claude Code

claude mcp add es617-obsidian-sync-mcp -- npx -y obsidian-sync-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "es617-obsidian-sync-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "obsidian-sync-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.
