Obsidian MCP Server

Overview

Obsidian MCP Server connects any MCP-compatible agent to a local Obsidian vault. Agents can read notes, create and update files, search by tag or keyword, and navigate the graph — turning your personal knowledge base into live context for any agent session. Built on the Obsidian Local REST API plugin, it runs entirely locally with no cloud dependency.

Best for

Best for
Knowledge workers and researchers who use Obsidian as their primary note store and want agents to read and write it

Use cases

• Pull relevant notes into an agent session as context before drafting
• Create and file meeting notes or research summaries directly from an agent
• Search the vault for prior decisions before starting a new project
• Sync agent-generated content back into the knowledge base automatically

Notes

Why it matters

Obsidian is where many builders and researchers keep their most valuable context. An MCP server here means agents stop working from scratch and start from your accumulated knowledge — meeting notes, research, decisions, all available in the same session.

How teams use it in production

Point the server at a specific vault folder rather than the root to keep context tight. Combine with a filesystem MCP for broader file operations, and use the search tool to pull only the most relevant notes before generating output.

What to watch

An official Obsidian MCP server is the natural next step as Obsidian expands its plugin ecosystem. Until then, this community server is the most-used path and works reliably with the Local REST API plugin.
