Workflowy MCP Server & CLI

A feature-rich Model Context Protocol (MCP) server and Command Line Interface (CLI) for Workflowy written in Go. Connect your AI assistant (Claude, ChatGPT, etc.) to your Workflowy data or run commands from a terminal emulator or script, including search, bulk replace, usage reports, and offline access capabilities.

Why This Workflowy MCP Server?

• Full-text search with regex
• Bulk search & replace
• Content transformation (split, clean, pipe to LLMs)
• Usage reports (stale nodes, size analysis, mirrors)
• Sandboxed AI access with --write-root-id
• Offline mode via backup files
• CLI + MCP server in one tool
• Caching for performance
• Homebrew installation
• Basic CRUD operations
• Using short IDs (Copy Internal Link)

Quick Start

Install via Homebrew

brew install mholzen/workflowy/workflowy-cli

Configure Your API Key

mkdir -p ~/.workflowy
echo "your-api-key-here" > ~/.workflowy/api.key

Get your API key at https://workflowy.com/api-key/

Run Your First Command

# Get the top-level nodes, and nodes two levels deep
workflowy get

# Generate a report showing where most of your nodes are
workflowy report count | pbcopy   # paste directly into Workflowy!

Use pbcopy on macOS, clip on Windows, wl-copy on Linux, or xclip for X11 systems.

Use with Claude Desktop or Claude Code

Claude Code

claude mcp add --transport=stdio workflowy -- workflowy mcp --expose=all

Remove —expose=all to limit to read-only tools.

Claude Desktop

Add to your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "workflowy": {
      "command": "workflowy",
      "args": ["mcp", "--expose=all"]
    }
  }
}

Restart Claude Desktop and start asking Claude to work with your Workflowy!

CLI Features

Search Your Entire Outline

# Find all TODOs (case-insensitive)
workflowy search -i "foobar"

# Regex search for dates
workflowy search -E "<time.*>"

# Search within a specific subtree (using Internal Link)
workflowy search "bug" --item-id https://workflowy.com/#/1bdae4aecf00

Bulk Search and Replace

# Preview changes first (dry run)
workflowy replace --dry-run "foo" "bar"

# Interactive confirmation
workflowy replace --interactive "foo" "bar"

# Use regex capture groups
workflowy replace "TASK-([0-9]+)" 'ISSUE-$1'

Some Common CRUD Operations

# Add a task to your inbox
workflowy create "Buy groceries" --parent-id=inbox

# Change the name of an item
workflowy update xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx --name "Project Plan v2"

# Move an item to a different parent
workflowy move <item-id> <new-parent-id>

# Mark a node as complete, using a short ID
workflowy complete https://workflowy.com/#/xxxxxxxxxxxx

# Resolve a short ID or target key to full UUID
workflowy id inbox

Transform Content

# Split a node's content by newlines into child nodes
workflowy transform <item-id> split -s "\n"

# Clean up text
workflowy transform <item-id> trim
workflowy transform <item-id> no-punctuation

# Pipe content through any shell command (e.g., an LLM)
workflowy transform <item-id> -x 'echo {} | llm "summarize this"'

Usage Reports

# Where is most of my content?
workflowy report count --threshold 0.01

# Which nodes have the most children?
workflowy report children --top-n 20

# Find stale content (oldest modified)
workflowy report modified --top-n 50

# Find most mirrored nodes (requires backup)
workflowy report mirrors --top-n 20

Data Access Methods

Choose the best method for your use case:

Method	Speed	Freshness	Offline	Best For
--method=get	Medium	Real-time	No	Specific items
--method=export	Fast*	1 min worst case (due to rate limiting)	No	Full tree access
--method=backup	Fastest	Stale	Yes	Bulk operations

*Cached after first fetch

Offline Mode with Dropbox Backup

Enable Workflowy's Dropbox backup and access your data offline:

workflowy get --method=backup
workflowy search -i "project" --method=backup

AI Assistant Workflows

Ask Claude:

• "Search my Workflowy for all items containing 'meeting notes'"
• "Show me nodes I haven't touched in 6 months"
• "Replace all 'v1' with 'v2' in my Project A folder"
• "What's taking up the most space in my outline?"
• "Which nodes are mirrored the most?"
• "Move this item to my inbox"

CLI Workflows

# Morning review: find stale items
workflowy report modified --top-n 20

# Weekly cleanup: find oversized nodes
workflowy report count --threshold 0.05

# Find unnecessary mirrors
workflowy report mirrors --top-n 20

# Bulk rename: update project prefix
workflowy replace "OLD-" "NEW-" --parent-id projects-folder-id

# Split pasted content into child nodes
workflowy transform <item-id> split -s "\n"
