🎯 OmniFocus Operator

The last OmniFocus MCP Server you'll ever need.

Python 3.12+ PyPI Tests 2561 Coverage 97% macOS only

Production-grade MCP server exposing OmniFocus as structured task infrastructure for AI agents. Agent-first design, SQLite-cached performance, 2,561 tests.

→ See the full landing page — features, architecture, benchmarks, and comparison

🚀 Quick Start

Prerequisites: macOS, OmniFocus 4, Python 3.12+

🪄 Not sure where this config goes? The setup wizard on the landing page walks you through it step-by-step — including auto-merging with your existing config.

For Claude Desktop

Paste this into ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "omnifocus-operator": {
      "command": "uvx",
      "args": ["omnifocus-operator"]
    }
  }
}

uvx downloads, isolates, and runs the server automatically. No install step.

First run: OmniFocus shows a one-time permission dialog. Tick the box, click Run Script. You won't see it again.

For Claude Code, OpenCode, Cursor…

Ask your agent — copy this prompt:

Add this MCP server to my client config. Just edit the config file — don't install anything, don't run any scripts.

"omnifocus-operator": {
  "command": "uvx",
  "args": ["omnifocus-operator"]
}

⚠️ This doesn't work with Claude Desktop — Desktop has no config-editing tools. Use the manual paste above.

git clone https://github.com/HelloThisIsFlo/omnifocus-operator.git
cd omnifocus-operator
uv sync

See CONTRIBUTING.md for dev workflow details.

✨ Features

  • ⚡ 46ms reads — SQLite caching gives 30–60x faster reads than bridge-only servers

  • 🛠️ 11 MCP tools — lookups, filtered lists, task creation & editing

  • 🤖 Agent-first design — warnings that teach, errors that educate, guidance in every response

  • 🧪 2,561 tests, 97% coverage — strict mypy, no corners cut

  • 🛡️ Graceful degradation — server stays alive no matter what, always recoverable

  • 🔄 Automatic fallback — SQLite → OmniJS bridge when needed

See the full documentation for architecture details, examples, and deep dives.

🛠️ Available Tools

Lookups

Tool

Description

get_all

Full OmniFocus database as structured data (last-resort debugging)

get_task

Single task by ID — urgency, availability, dates, tags, parent, project

get_project

Single project by ID — status, review interval, next task

get_tag

Single tag by ID — availability, parent hierarchy

List & Filter

Tool

Description

list_tasks

Filter by date, availability, flags, tags, project, parent subtree, search — with pagination, field selection, and presence-flag derivation

list_projects

Filter by status, folder, review schedule, flags

list_tags

List tags with parent hierarchy

list_folders

List folders with parent hierarchy

list_perspectives

List custom perspectives

Write

Tool

Description

add_tasks

Create tasks with full field control — parent, tags, dates, flags, notes, repetition rules, parallel/sequential, completes-with-children

edit_tasks

Patch semantics — update fields, move tasks, complete/drop, manage tags, repetition rules, and hierarchy properties

All read tools are idempotent. Write tools reference projects and tags by name or ID.

🔍 Tool Examples

Filter tasks (list_tasks):

{
  "query": {
    "flagged": true,
    "due": "soon",
    "availability": "remaining",
    "include": ["notes"],
    "limit": 10
  }
}

Create a task (add_tasks):

{
  "items": [{
    "name": "Review Q3 roadmap",
    "parent": "Work Projects",
    "tags": ["Planning"],
    "dueDate": "2026-03-15T17:00:00",
    "flagged": true,
    "estimatedMinutes": 30,
    "note": "Focus on v1.3-v1.5 milestones"
  }]
}

Edit with patch semantics (edit_tasks):

{
  "items": [{
    "id": "oRx3bL_UYq7",
    "dueDate": null,
    "actions": {
      "tags": {"add": ["Urgent"]},
      "move": {"ending": "Work Projects"}
    }
  }]
}
