Obsidian MCP Server

Obsidian MCP Server is an MCP server that connects large language model clients to local Obsidian vaults using the community Local REST API plugin. Developed by Nate Strong, the server allows knowledge workers, researchers, and developers to interface directly with their markdown-based personal knowledge base through conversational AI interfaces. By communicating through the Local REST API running inside an active Obsidian instance, the server exposes endpoints for reading, querying, and updating notes and vault contents. Users can integrate AI assistants such as Claude Desktop to analyze personal documentation, summarize research logs, generate new markdown files, and retrieve relevant entries based on prompts. Because it interacts directly with local files exposed via the local API, it allows users to keep control over their local notes without having to upload entire directories to third-party services. This setup enables automated note-taking workflows and deep integration between local markdown archives and AI agent tools.

What you can do with Obsidian MCP Server

• Querying existing Obsidian notes and extracting relevant passages to answer specific user questions directly inside an MCP client interface. - Summarizing lengthy meeting logs, daily notes, or research papers stored as markdown files across different folders in your vault. - Creating new notes or appending generated summaries, tasks, and reference material directly to existing markdown documents in Obsidian. - Searching vault contents by keywords or document structure to quickly surface connections between disparate personal knowledge topics.

Because setup requires pairing the server with your local Obsidian environment and the Local REST API plugin, refer to the repository instructions at https://github.com/natestrong/obsidian-mcp for exact installation commands, build steps, and configuration settings for your MCP client.

Which MCP clients work with Obsidian MCP Server?

Obsidian MCP Server works with any standard Model Context Protocol client that supports local MCP server connections. This includes tools such as Claude Desktop, Cursor, and other compatible MCP developer environments that can run local command-line servers.

What are the prerequisites for using this server?

You need an active Obsidian installation running on your machine with the Local REST API community plugin installed and configured. The plugin generates the local API endpoint and authentication details that the MCP server uses to communicate with your vault.
