Obsidian MCP Server is a lightweight implementation that enables AI assistants like Claude and Cursor to read from and write to Obsidian vaults through direct filesystem access. Developed by Marcel Marais, it provides tools for retrieving file lists, reading file contents with flexible matching, collecting open todos across notes, and creating or updating markdown files. The server operates independently of the Obsidian application, making it particularly valuable for users who want their AI assistants to interact with their knowledge base without requiring the Obsidian application to be running.
