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.

Saving a Claude Desktop conversation into an Obsidian vault, then searching the vault from chat

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).

bash

npx mcp-obsidian-cli

Claude Desktop config

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

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:

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:

yaml

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.
