MCP server that wraps the Obsidian CLI, giving AI assistants full access to Obsidian's native API — search index, wikilink resolution, tasks, properties, daily notes, backlinks, and 80+ commands — through the Model Context Protocol.

Why this exists

Every existing Obsidian MCP server takes one of two approaches: the Local REST API plugin (requires API keys, HTTP overhead, limited command surface) or raw filesystem access (no Obsidian awareness — no search index, no wikilink resolution, no task queries). Both miss the point.

mcp-obsidian-cli wraps the Obsidian CLI plugin, which talks directly to the running Obsidian instance via IPC. This means full access to Obsidian's internal APIs with zero configuration — no API keys, no REST plugins, no token management.

Quick start

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 the CLI plugin active
• obsidian on your PATH
• 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
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 note
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	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"
timeoutMs: 15000

Config precedence: env vars > config file > hardcoded defaults
