How to Set Up and Use OmniFocus
OmniFocus MCP is a TypeScript MCP server that connects AI assistants to OmniFocus on macOS, exposing 12 tools for reading, creating, editing, and deleting tasks, projects, and tags. It also provides read-only MCP resources for common views like Inbox, Today, and Flagged, making it possible to ask Claude to process meeting transcripts into action items, reorganize projects, or query your task database in natural language — all without leaving your AI chat interface.
Prerequisites
- macOS with OmniFocus 3 or later installed
- Node.js 18 or higher
- An MCP-compatible client such as Claude Desktop or Claude Code CLI
- OmniFocus must be running while the MCP server is in use
Add the server to Claude Desktop
The server is published to npm as 'omnifocus-mcp' and can be run via npx without a separate install step. Add the configuration block to your claude_desktop_config.json.
Or add via Claude Code CLI
If you use Claude Code CLI, register the server with a single command.
claude mcp add omnifocus -- npx -y omnifocus-mcpEnsure OmniFocus is running
The MCP server communicates with OmniFocus via macOS scripting. OmniFocus must be open in the background whenever the server is active.
Restart your MCP client
Restart Claude Desktop or reload the MCP server list in your client so it picks up the new omnifocus-mcp configuration.
Test with a simple query
Ask Claude to list your flagged tasks to verify the connection between the MCP server and OmniFocus is working.

Example prompts for managing OmniFocus tasks and projects through Claude.
- "Show me all my flagged tasks due this week"
- "I just finished a meeting. Here are the notes: [paste notes]. Create OmniFocus tasks for every action item assigned to me"
- "Create a new project called 'Q3 Launch' with tasks for each phase: planning, development, QA, release"
- "Move all tasks tagged 'waiting' to the project 'On Hold'"
- "How many open tasks do I have in each project? Give me a summary table"
- "Mark the task 'Submit expense report' as complete"Troubleshooting OmniFocus
Server connects but cannot read tasks or gets scripting errors
Make sure OmniFocus is running. The server uses macOS scripting to communicate with OmniFocus — if the app is closed or sandboxed, all tool calls will fail. Grant automation permissions when prompted by macOS.
npx fails to download or run omnifocus-mcp
Check your internet connection and Node.js version (18+ required). Run 'npm install -g omnifocus-mcp' to install it globally if npx continues to fail, then update the config to use 'omnifocus-mcp' as the command instead of 'npx'.
Tasks are created but missing fields like due date or project
Specify the desired fields explicitly in your prompt (e.g., 'due tomorrow', 'in project X', 'tagged urgent'). The add_omnifocus_task tool accepts metadata fields but the AI must be instructed to populate them.
