omnifocus-operator 1.4.2

MCP server exposing OmniFocus as structured task infrastructure for AI agents

🎯 OmniFocus Operator

The last OmniFocus MCP Server you'll ever need.

Production-grade MCP server exposing OmniFocus as structured task infrastructure for AI agents. Agent-first design, SQLite-cached performance, 2,558 tests.

🚀 Quick Start

Prerequisites: macOS, OmniFocus 4, Python 3.12+

Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json):

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

That's it. No install step — uvx downloads, isolates, and runs the server automatically.

Or just ask your agent:

Set up the OmniFocus Operator MCP server for me — uvx omnifocus-operator

Development install (contributors)

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
• 🧪 2,558 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"}
    }
  }]
}

Patch semantics cheat sheet:

Input	Meaning
Field omitted	No change
Field set to null	Clear the value
Field set to a value	Update
