MCP Obsidian Cli

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.

Installing this? Start at Install. One prompt in Claude Code handles the whole setup.

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.

Using this from Claude Code? The native obsidian-cli skill fits better there: direct CLI, no MCP layer. Installing is separate. The prompt below runs in Claude Code.

Install

Run the prompt below in Claude Code. It checks Node, enables the Obsidian CLI, writes your Claude Desktop config, and verifies the connection. Only hand-edit the config if that path fails.

Fetch https://raw.githubusercontent.com/stonematt/mcp-obsidian-cli/master/docs/INSTALL.md

and follow it end to end to install the mcp-obsidian-cli MCP server for my Claude Desktop. Ask me for my Obsidian vault name and folder path, then handle everything else — check Node, enable the Obsidian CLI, edit my Claude Desktop config, and verify it works.

Full walkthrough, including failure modes: [docs/INSTALL.md](https://github.com/stonematt/mcp-obsidian-cli/blob/master/docs/INSTALL.md).

Run the server directly. This starts the server in your terminal and installs nothing:

npx mcp-obsidian-cli

Requirements

The install prompt checks each of these. Listed here for reference:

• 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. macOS auto-detects it inside the Obsidian app bundle, so there is nothing to configure. Linux and Windows have no auto-detection: point OBSIDIAN_CLI_PATH at the binary yourself.
• 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:

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

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.

Manual config (if you're not using Claude Code)

Automated installers should use the prompt under Install, which handles vault name, CLI path, and verification. This block is the hand-edit fallback.

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

{

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

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
