Obsidian MCP Server: Enhancing AI Application Integration through MCP

Overview: What is Obsidian MCP Server?

Obsidian MCP Server is an advanced implementation of the Model Context Protocol (MCP), designed to enable AI applications like Claude Desktop, Continue, and Cursor to interact with Obsidian vaults. This server provides a powerful toolkit for managing notes, directories, tags, and more within your vault, allowing seamless integration into your AI workflows.

🔧 Core Features & MCP Capabilities

Obsidian MCP Server excels in several key areas:

Data Access & Manipulation

• Read & Search Notes: Quickly access and search through your Obsidian notes.
• Create & Edit Notes: Easily add new content or make edits to existing notes.
• Move & Delete Notes: Organize your vault structure by moving or permanently removing notes.

Tag Management

• Add, Remove, Rename Tags: Efficiently manage tags across multiple notes for better organization and categorization.
• Search Vault Contents: Quickly find relevant information within the vault using powerful search capabilities.

These features are achieved through MCP's standardized protocol, making it easy for developers to integrate tools with Obsidian vaults without custom development efforts.

Obsidian MCP Server fully supports key components like resources, tools, and prompts in the MCP protocol. This ensures seamless integration with popular AI applications.

🚀 Getting Started with Installation

To get started with Obsidian MCP Server, follow these steps:

1. Clone the Repository

   git clone https://github.com/StevenStavrakis/obsidian-mcp
   cd obsidian-mcp
   

2. Install Dependencies

   npm install
   

3. Build the Server

   npm run build
   

4. Configure Claude Desktop: Add the server configuration to claude_desktop_config.json.

   For macOS:

   {
       "mcpServers": {
           "obsidian": {
               "command": "node",
               "args": ["<absolute-path-to-obsidian-mcp>/build/main.js", "/path/to/your/vault"]
           }
       }
   }
   

   For Windows:

   {
       "mcpServers": {
           "obsidian": {
               "command": "node",
               "args": ["<absolute-path-to-obsidian-mcp>/build/main.js", "\\path\\to\\your\\vault"]
           }
       }
   }
   

Replace "/path/to/your/vault" or "\\path\\to\\your\\vault" with the absolute path to your Obsidian vault.

5. Restart Claude Desktop: Ensure the server is connected by looking for the hammer icon.

💡 Key Use Cases in AI Workflows

Workflow 1: Automated Note Management

Imagine a scenario where you’re working on multiple projects simultaneously and need to manage notes efficiently. With Obsidian MCP Server, you can automate tasks like tagging important notes, creating new directories, or searching through your vault for specific information.

Workflow 2: Seamless Integration with AI Tools

When using an AI tool like Claude Desktop, Obsidian MCP Server allows it to directly interact with your Obsidian vault. This means generating prompts based on note content, accessing metadata, and even performing actions within the vault dynamically.

🔌 Integration with MCP Clients

Obsidian MCP Server is designed to work seamlessly with various MCP clients:

• Claude Desktop: Full support for resources, tools, and prompts.
• Continue: Supports tools and offers a powerful AI integration.
• Cursor: Primary support for tools, providing a versatile AI experience.

📊 Performance & Compatibility Matrix

Client	Obsidian Vault Access	Tool Deployment	Prompt Execution
Claude Desktop	✅	✅	✅
Continue	✅	✅	❌
Cursor	❌	✅	❌

This matrix highlights the compatibility of Obsidian MCP Server with different clients. Claude Desktop benefits fully from all features, while Continue supports tools but not prompts.

🛠️ Advanced Configuration & Security

Configuring the Server

Ensure you provide only the necessary permissions and paths to maintain security:

{
    "mcpServers": {
        "obsidian": {
            "command": "npx",
            "args": ["-y", "obsidian-mcp", "/path/to/your/vault"]
        }
    }
}

Review tool actions before approving and keep the vault path secure to prevent unauthorized access.

Backup Recommendations

Regularly back up your Obsidian vault using Git or any other backup method recommended by Obsidian. This ensures data safety during server operations.
