Summary

This Obsidian MCP server, developed by cyanheads, enables AI models to interact with Obsidian vaults through a standardized interface. Built with TypeScript and leveraging the Model Context Protocol SDK, it provides tools for file operations, content search, and metadata management within Obsidian. The implementation features atomic operations, efficient query processing, and automatic timestamp handling. It's particularly useful for AI assistants and applications needing to manage knowledge bases in Obsidian, enabling use cases like note-taking, content organization, and information retrieval without dealing directly with Obsidian's API complexities.
