Configuration

{
  "mcpServers": {
    "sunwood-ai-labs-obsidian-mcp": {
      "command": "/path/to/obsidian-mcp/build/index.js",
      "args": [],

This MCP server enables Obsidian integration by exposing vault data as resources, providing tools to access vault contents, and integrating with Obsidian through a secure API. It lets you query vault structures, access metadata, and extend Obsidian workflows via the MCP protocol.

How to use

You interact with this MCP server through an MCP client. The server represents Obsidian vault contents as resources and offers a dedicated tool to fetch vault data. Use the client to request vault information, browse the vault structure, and trigger data retrieval in a structured, JSON-friendly format. The integration focuses on practical data access and combineable actions that fit into your existing Obsidian workflows.

How to install

Prerequisites you need before installing the MCP server:

Node.js v18+
TypeScript 5.3+
An Obsidian API key set as OBSIDIAN_API_KEY environment variable

Install dependencies, build, and run in watch mode to auto-rebuild on changes:

npm install

npm run build

npm run watch

Configuration and startup

Place the MCP server config into your environment where the MCP launcher can read it. The server exposes itself as a local process you start via the specified command. Here is the example configuration provided for this MCP server setup:

{
  "mcpServers": {
    "obsidian_mcp": {
      "command": "/path/to/obsidian-mcp/build/index.js",
      "env": {
        "OBSIDIAN_API_KEY": "your-api-key-here"
      }
    }
  }
}
