What is the Obsidian MCP server?

The Obsidian MCP server is a middleware service that allows various client tools to access your Obsidian knowledge base through standard protocols. It provides functions to search for notes and retrieve note content, enabling you to conveniently use the knowledge in Obsidian across different tools.

How to use the Obsidian MCP server?

You need to configure the MCP server connection in your client tools (such as VS Code or Claude) and specify the path of the Obsidian knowledge base. After the configuration is complete, you can directly query and use the note content in Obsidian through the client.

Use cases

This service is particularly useful when you want to directly use the Obsidian note content in code editors, AI assistants, or other tools. For example, you can quickly refer to technical notes while programming, or let the AI assistant answer questions based on your personal knowledge base.

Main features

Note searchSearch for notes in the Obsidian knowledge base based on topic keywords
Retrieve note contentGet the complete note content and metadata through the note path

Advantages and limitations

Advantages
Supports multiple client tools to access the Obsidian knowledge base
Lightweight implementation with high performance
Uses the standard MCP protocol with good compatibility
Limitations
Requires installing the Obsidian Metadata Extractor plugin
Currently, the functions are relatively basic, only supporting note search and retrieval
Requires manual configuration of the client connection

How to use

Install the Metadata Extractor plugin
Install and enable the metadata-extractor plugin in Obsidian. It will generate the metadata.json file required by the server.
Configure the VS Code client
Add the server configuration to the.vscode/mcp.json file in the VS Code workspace.
Configure the Claude client
Add the MCP server settings to Claude's configuration file.

Usage examples

Refer to technical notes while programmingWhen you are writing code in VS Code, you can directly search for and view relevant technical notes in Obsidian.
Let the AI assistant answer based on the personal knowledge baseConfigure Claude to use your Obsidian knowledge base so that its answers are based on your personal note content.
