Obsidian Cli MCP Server

mcp-obsidian-cli

Your thinking starts in Claude Desktop, not in Obsidian. You research, draft, argue with the model, and when something's worth keeping you say "save this to my vault." It lands in the right place: your template, your properties, today's daily note, wired into your link graph. No tab-switch, no copy-paste.

Two halves:

• Capture — turn a conversation into a real note, filed where it belongs.
• Augment — pull what's already in the vault (backlinks, full-text search) back into the chat to inform or update a note.

Needs Obsidian running. It can sit minimized, so you never switch to it.

On Claude Code? The native obsidian-cli skill fits better there: direct CLI, no MCP layer. Use that.

Quick start

New here? The Install brief has a one-line prompt you paste into Claude Code — it then does the whole setup (checks Node, enables the Obsidian CLI, edits your Claude Desktop config, verifies it works).

npx mcp-obsidian-cli

Claude Desktop config

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "obsidian": {
      "command": "npx",
      "args": ["-y", "mcp-obsidian-cli"],
      "env": {
        "OBSIDIAN_VAULT": "my-vault"
      }
    }
  }
}

Requirements

• Obsidian running with its command line interface enabled (Settings → General → Advanced → Command line interface). The CLI ships built into Obsidian — nothing extra to install.
• obsidian-cli reachable — on your PATH, or point OBSIDIAN_CLI_PATH at it (typically /Applications/Obsidian.app/Contents/MacOS/obsidian-cli on macOS).
• Node.js >= 18

Full walkthrough: docs/INSTALL.md.

How it works

The server exposes Obsidian CLI commands as MCP tools. A generic pass-through tool handles the full CLI surface (80+ commands), plus typed convenience tools for common operations:

The generic obsidian tool means the MCP server never falls behind the CLI — new CLI commands work immediately without a server update.

Environment variables

Config file

The server can read settings from a YAML config file:

• Default: ~/.config/mcp-obsidian-cli/config.yaml
• With XDG_CONFIG_HOME: $XDG_CONFIG_HOME/mcp-obsidian-cli/config.yaml

Config file format:

vault: "my-vault"
cliPath: "obsidian-cli"
timeoutMs: 15000

Config precedence: env vars > config file > hardcoded defaults

What it can do

It talks to the running Obsidian instance, so it works with your vault the way Obsidian sees it:

• Backlinks and full-text search across your resolved link graph and search index (the augment half).
• Templater templates and typed frontmatter properties when creating or updating notes.
• Daily notes, task queries, and tag counts.
• 80+ commands through the generic pass-through. No API keys, no REST plugin. Just the official Obsidian CLI.
