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.
About mcp-obsidian
fazer-ai/mcp-obsidian
MCP server for Obsidian (TypeScript + Bun)
Exposes 20+ tools for Claude to read, write, and search Obsidian vaults via the Local REST API plugin, including note CRUD operations, periodic note management, Dataview/JsonLogic querying, and command execution. Implements MCP over stdio with environment-based authentication, deployable via `bunx` directly into Claude Desktop or compatible LLM clients. Supports both active note manipulation and arbitrary file operations across the vault with fine-grained content patching (headings, block references, frontmatter).
