Obsidian Cli

Obsidian CLI npm version npm downloads MCP Registry Node License: MIT

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

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:

Tool	Description
obsidian	Generic pass-through — run any CLI command (ships intent→verb cheatsheet, pre-call manifest validation, reload detection)
obsidian_help	Manifest-backed help — list verbs by category, or look up a single verb / doc topic
obsidian_daily_read	Read today's daily note
obsidian_daily_append	Append to daily note
obsidian_read	Read a note by name or path
obsidian_search	Full-text search with context
obsidian_tags	List tags with counts
obsidian_tasks	Query tasks (daily, todo, done)
obsidian_properties	Read frontmatter properties
obsidian_create	Create a new plain note (no Templater expansion)
obsidian_create_from_template	Create a note from a Templater template (expands <% ... %> placeholders)
obsidian_property_set	Set a frontmatter property
obsidian_backlinks	List backlinks to a note
obsidian_files	List vault files
obsidian_recents	Recently opened files

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

Environment variables

Variable	Default	Description
OBSIDIAN_VAULT	(none)	Target vault by name
OBSIDIAN_CLI_PATH	obsidian-cli	Path to CLI binary
OBSIDIAN_TIMEOUT_MS	15000	Command timeout
XDG_CONFIG_HOME	~/.config	Base path for config file

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.
