workflowy-mcp 0.3.3

MCP server for WorkFlowy API integration

WorkFlowy MCP Server

A Model Context Protocol (MCP) server that integrates WorkFlowy's outline and task management capabilities with LLM applications.

MCP Tools Available

Tool	Description
workflowy_create_node	Create new nodes with name, notes, and layout mode
workflowy_update_node	Update existing node properties
workflowy_get_node	Retrieve a specific node by ID
workflowy_list_nodes	List child nodes of a specific parent
workflowy_delete_node	Delete a node and its children
workflowy_complete_node	Mark a node as completed
workflowy_uncomplete_node	Mark a node as uncompleted

⚠️ Important Limitations

The WorkFlowy API has significant discovery limitations:

• ✅ CAN list root-level nodes (call list_nodes without parent_id)
• ✅ CAN navigate down the tree by listing children of discovered nodes
• ❌ CANNOT search for nodes by name or content
• ❌ CANNOT jump directly to deeply nested nodes
• ❌ CANNOT use node IDs from WorkFlowy web URLs (they use different IDs)

Practical Impact:

• You must navigate hierarchically from root to find existing nodes
• No text search means manually traversing the tree to find specific content
• Deep nodes require multiple list operations to reach
• The web interface IDs (workflowy.com/#/abc123) are NOT compatible with API IDs

Quick Start

Prerequisites

• Python 3.10 or higher
• WorkFlowy account with API access
• Claude Desktop or other (local, since it's a python package) MCP-compatible client

Installation

Option 1: Install from PyPI (Recommended)

# Install the package
pip install workflowy-mcp

Option 2: Quick Setup Script

# Download and run the setup script
curl -sSL https://raw.githubusercontent.com/yourusername/workflowy-mcp/main/install.sh | bash

# Or on Windows:
# irm https://raw.githubusercontent.com/yourusername/workflowy-mcp/main/install.ps1 | iex

Option 3: Manual Installation from Source

# Clone the repository (if you want to contribute or modify)
git clone https://github.com/vladzima/workflowy-mcp.git
cd workflowy-mcp
pip install -e .

Configuration

1. Get your WorkFlowy API key:

   • From WorkFlowy

2. Configure client: Edit your client configuration (Claude Desktop example):

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

   Add to the mcpServers section:

   {
     "mcpServers": {
       "workflowy": {
         "command": "python3",
         "args": ["-m", "workflowy_mcp"],
         "env": {
           "WORKFLOWY_API_KEY": "your_actual_api_key_here",
           // Optional settings (uncomment to override defaults):
           // "WORKFLOWY_API_URL": "https://workflowy.com/api/v1",
           // "WORKFLOWY_REQUEST_TIMEOUT": "30",
           // "WORKFLOWY_MAX_RETRIES": "3",
           // "WORKFLOWY_RATE_LIMIT_REQUESTS": "60",
           // "WORKFLOWY_RATE_LIMIT_WINDOW": "60"
         }
       }
     }
   }
   

3. Restart your client to load the MCP server

Usage

Once configured, you can use WorkFlowy tools with your agent:

Working with New Nodes

"Create a new WorkFlowy node called 'Project Tasks'"
# Returns: Created node with ID: abc-123-def

"Create a todo item 'Review PR' under parent node abc-123-def"

"Mark the node abc-123-def as completed"

"List all children of node abc-123-def"

Navigating Existing Nodes

Since there's no search, you must navigate from root:

"List my root-level WorkFlowy nodes"
# Returns: List of top-level nodes with their IDs

"List children of node abc-123-def"
# Navigate deeper into your outline

"Get details for node abc-123-def"

"Update node abc-123-def with new notes"

Note: The node IDs from the web interface URLs are NOT compatible with the API.

    "modifiedAt": 1234567890               # Unix timestamp
}

Error Handling

All tools return a consistent error format:

{
    "success": false,
    "error": "error_type",
    "message": "Human-readable error message",
    "context": {...}  // Additional error context
}

Performance

• Automatic rate limiting prevents API throttling
• Token bucket algorithm for smooth request distribution
• Adaptive rate limiting based on API responses
• Connection pooling for efficient HTTP requests
