KObsidian
Let Claude or Cursor read and maintain an Obsidian vault as a filesystem-first wiki while you ship.
Overview
kObsidian is an MCP server for the Build phase that gives coding agents filesystem-first read and write access to an Obsidian vault, with optional Local REST API tools for workspace and Dataview.
What is this MCP server?
- Filesystem-first vault access via OBSIDIAN_VAULT_PATH—no cloud sync dependency for core tools
- Optional Obsidian Local REST API for workspace, commands, and Dataview live queries
- stdio MCP over npm (npx kobsidian-mcp) with protocol version 2025-11-25
- Inspired by Karpathy-style LLM-maintained wikis inside your existing Obsidian graph
- TLS toggle (OBSIDIAN_API_VERIFY_TLS) for self-signed Local REST API certificates
- Server version 0.2.1
- stdio transport via npm package kobsidian-mcp
- Required env: OBSIDIAN_VAULT_PATH; optional OBSIDIAN_API_URL default https://127.0.0.1:27124

What problem does it solve?
Your best context lives in Obsidian but your agent cannot safely navigate vault paths, update notes, or query Dataview without a dedicated bridge.
Who is it for?
Indie builders who already use Obsidian for specs and want the same vault editable from Claude Code or Cursor during build and research.
Skip if: Teams that need hosted team wikis with no local Obsidian install or vault on disk.
What do I get? / Deliverables
After install, your agent can maintain a linked wiki in your vault path and optionally query live Obsidian workspace data through MCP tools.
- MCP tools operating on vault markdown and attachments on disk
- Optional live workspace, command, and Dataview query access via REST API

How it compares
Vault filesystem MCP integration, not a standalone note-taking app or generic file-search skill.
Common Questions / FAQ
Who is KObsidian for?
Solo and small-team builders who keep product and technical notes in Obsidian and want MCP agents to read, update, and organize that vault from the IDE.
When should I use KObsidian?
Use it when you are building or researching and need the agent to work directly on markdown files in a known vault path, especially for LLM-maintained wikis and runbooks.
How do I add KObsidian to my agent?
Register the stdio server via npx (kobsidian-mcp), set OBSIDIAN_VAULT_PATH to your vault’s absolute path, and add optional OBSIDIAN_API_URL if you use the Local REST API plugin.
