This MCP server for Obsidian allows AI assistants to interact with your Obsidian vault using the Model Context Protocol. It provides a standardized interface for reading, writing, and manipulating notes in your vault, making it easier to integrate AI capabilities with your knowledge base.
Clone the repository to your local machine
git clone https://github.com/username/obsidian-mcp.git
Install dependencies
npm install
Build the project
npm run build
Configure environment variables by creating a .env file with:
apiKey=<Your API Token>
port=27123
host=127.0.0.1
To use this MCP server with Claude Desktop App, add the following to your Claude configuration:
{
"mcpServers": {
"Obsidian": {
"command": "node",
"args": ["/Users/<Your Own Path>/obsisian-mcp/build/index.js"],
"env": {
"apiKey": "<Your API Token>",
"port": "27123",
"host": "127.0.0.1"
}
}
}
}
Be sure to replace <Your Own Path> with the actual path to where you cloned the repository and <Your API Token> with the token generated from the Local REST API plugin.
The MCP server provides several tools for interacting with your Obsidian vault:
{
"path": "path/to/note.md"
}
{}
Lists files and folders in the entire vault or under a specified folder:
{
"path": "optional/folder/path"
}
Inserts content into an existing note relative to a heading, block reference, or frontmatter field:
{
"path": "path/to/note.md",
"operation": "append|prepend|replace",
"targetType": "heading|block|frontmatter",
"target": "target_identifier",
"content": "content to insert"
}
Search Obsidian notes using JsonLogic format queries:
{
"query": {
// JsonLogic query object
}
}
This tool allows for complex search operations using the JsonLogic format to find specific notes in your vault.
To add this MCP server to Claude Code, run this command in your terminal:
claude mcp add-json "Obsidian" '{"command":"node","args":["/Users/<Your Own Path>/obsisian-mcp/build/index.js"],"env":{"apiKey":"<Your API Token>","port":"27123","host":"127.0.0.1"}}'See the official Claude Code MCP documentation for more details.
There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.
If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.
To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".
When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:
{
"mcpServers": {
"Obsidian": {
"command": "node",
"args": [
"/Users/<Your Own Path>/obsisian-mcp/build/index.js"
],
"env": {
"apiKey": "<Your API Token>",
"port": "27123",
"host": "127.0.0.1"
}
}
}
}To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.
Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.
The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.
You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.
