Overview
What is Obsidian MCP Server?
It is an Obsidian plugin that runs a local MCP (Model Context Protocol) server using SSE, enabling external applications such as AI assistants or scripts to interact with your Obsidian vault through a standardized interface. This work-in-progress plugin is designed for Obsidian users who want to connect external tools to their notes.
How to use Obsidian MCP Server?
Install the plugin, configure the embedding provider and server port in the Settings panel, then run the “Re-index Vault (MCP Server)” command from the command palette. Start the server with “Start MCP Server” and connect your MCP client to the SSE endpoint (e.g., http://localhost:8080/sse). After connection, available tools can be used from the client.
