OmniFocus-MCP

OmniFocus MCP Server

A Model Context Protocol (MCP) server that integrates with OmniFocus to enable Claude (or other MCP-compatible clients) to interact with your tasks and projects.

Overview

This MCP server creates a bridge between AI assistants (like Claude) and your OmniFocus task management system. It gives AI models the ability to view, create, edit, and remove tasks and projects in your OmniFocus database through natural language conversations. Some ways you could use it:

• Translate the PDF of a syllabus into a fully specificed project with tasks, tags, defer dates, and due dates.
• Turn a meeting transcript into a list of actions
• Create visualizations of your tasks, projects, and tags
• Process multiple tasks or projects in a single operation
• Bulk manage your OmniFocus items efficiently

Known Issues

• Dump_database tool currently fails for very large omnifocus databases.

Roadmap

• Enable the client to interact with perspectives ✅ (Added list_perspectives and get_perspective_view)
• Benefit from MCP resource and prompt features
• Add support for the new planned date type in Omnifocus 4.7
• Support manipulating notifications for projects and tasks

🚀 Quick Start

Prerequisites

• macOS with OmniFocus installed

Connecting to Claude

1. In Claude Desktop, add this MCP server to your configuration file at:

2. Add the following configuration:

3. Restart Claude Desktop

Use Cases

Efficient Task Queries

Use the new query_omnifocus tool for fast, targeted searches:

"Show me tasks due today" "Get all flagged items in my Work project"
"Count how many tasks are in each project"

Reorganize your projects, tasks, and tags

"I want every task to have an energy level tag. Show me a list of all the tasks that don't have an energy level tag and your suggestions for what tag to add. I'll make any changes I think are appropriate. Then make the changes in OmniFocus."

Add tasks from any conversation

"Ok, thanks for the detailed explanation of why the rule of law is important. Add a recurring task to my activism project that reminds me to call my representative weekly. Include a summary of this conversation in the notes field."

Quick, Virtual Perspectives

Get a summary of your current tasks and manage them conversationally:

"Show me all my flagged tasks due this week"

Or create custom views:

"What are my next actions in the Work folder?"

Work with OmniFocus Perspectives

List and view your perspectives:

"What perspectives do I have available?" "Show me what's in my Inbox perspective" "Get the flagged items from my current perspective"

Process Transcripts or PDFs

Extract action items from meeting transcripts, academic research articles, or notes:

"I'm pasting in the transcript from today's meeting. Please analyze it and create tasks in OmniFocus for any action items assigned to me. Put them in my 'Product Development' project."

🔧 Available Tools

How It Works

This server uses AppleScript to communicate with OmniFocus, allowing it to interact with the application's native functionality. The server is built using the Model Context Protocol SDK, which provides a standardized way for AI models to interact with external tools and systems.
