About obsidian-mcp-server

cyanheads/obsidian-mcp-server

Obsidian Knowledge-Management MCP (Model Context Protocol) server that enables AI agents and development tools to interact with an Obsidian vault. It provides a comprehensive suite of tools for reading, writing, searching, and managing notes, tags, and frontmatter, acting as a bridge to the Obsidian Local REST API plugin.

Implements a modular TypeScript architecture leveraging stdio transport for MCP communication with automatic reconnection, backed by an intelligent in-memory vault cache that provides fallback search functionality if the REST API becomes unavailable. Supports flexible file targeting (by path, active note, or periodic notes) and atomic frontmatter operations, with structured logging, Zod validation, and optional HTTP transport via Hono for alternative deployment scenarios.
