omniplan-mcp 0.4.0

MCP server for reading OmniPlan (.oplx) and Microsoft Project (.mpp) schedule files

OmniPlan MCP Server

A Model Context Protocol (MCP) server that lets Claude read and analyze project schedule files — OmniPlan (.oplx) and Microsoft Project (.mpp) formats.

Ask Claude questions like:

• "What's the current project schedule?"
• "List all milestones and their dates"
• "Show me tasks related to the robotic arm"
• "What's the overall progress percentage?"

Features

Feature	Description
📂 Read .mpp	Parse Microsoft Project files via OmniPlan bridge
📂 Read .oplx	Direct XML parsing (no OmniPlan needed)
🏛️ Full hierarchy	Groups, tasks, milestones with dates and progress
🔍 Search	Find tasks by keyword across the entire schedule
👤 Resources	List all human resources and assignments
📊 Summary	Phase overview, progress statistics, timeline
🔒 Safe concurrency	Direct AppleScript reading avoids temp-file conflicts when multiple sessions run

Prerequisites

Requirement	Notes
macOS	Required (for AppleScript/OmniPlan bridge)
Python 3.10+	For running the MCP server
OmniPlan	Only needed for .mpp files; .oplx works without it

Install OmniPlan (optional — only for .mpp files)

brew install --cask omniplan

First run: macOS may prompt for Accessibility/Automation permissions when OmniPlan is called via AppleScript. Grant them in System Settings → Privacy & Security → Automation.

Quick Start

1. Install

# Option A: One-line installer (recommended)
curl -fsSL https://raw.githubusercontent.com/cygnusyang/omniplan-mcp/main/install.sh | bash

# Option B: Manual clone
git clone https://github.com/cygnusyang/omniplan-mcp.git
cd omniplan-mcp
pip install -e .

2. Configure Claude Code

Add to your ~/.claude/settings.json:

uv run (recommended)

{
  "mcpServers": {
    "omniplan": {
      "command": "uv",
      "args": [
        "run",
        "--directory", "/Users/yourusername/.local/share/omniplan-mcp",
        "omniplan-mcp"
      ],
      "env": {}
    }
  }
}

pip install (after PyPI publish)

{
  "mcpServers": {
    "omniplan": {
      "command": "uvx",
      "args": ["omniplan-mcp"],
      "env": {}
    }
  }
}

Direct Python

{
  "mcpServers": {
    "omniplan": {
      "command": "/path/to/python3",
      "args": ["-m", "omniplan_mcp"],
      "env": {
        "PYTHONPATH": "/path/to/omniplan-mcp/src"
      }
    }
  }
}

3. Restart Claude Code

The MCP server will start automatically. You can now ask Claude about your project files!

Usage Examples

Read a project schedule

你：帮我读取 PLB1011 项目计划，看看有哪些阶段
Claude：调用 read_schedule → 显示完整任务树

List milestones

你：列出所有里程碑节点
Claude：调用 list_milestones → 显示所有 ◇ 里程碑

Search for tasks

你：搜索所有关于"机械臂"的任务
Claude：调用 search_tasks → 显示匹配的任务列表

Project summary

你：这个项目的整体进度怎么样？
Claude：调用 schedule_summary → 显示阶段概览和进度统计

export_schedule	Export schedule to various formats	filepath, format (optional), output_path (optional)
lookup_task	Find task by name, get its numeric ID	search_name
set_task_completed	Set task to 100% complete	task_id, include_subtree

set_task_duration	Change task duration	task_id, duration_seconds
clear_constraint_date	Remove locked start date	task_id
rename_task	Rename a task	task_id, new_name
delete_task	Delete a task and its children	task_id
add_task	Add a new task under a parent	parent_task_id, task_name, duration_seconds (optional)
save_document	Save the OmniPlan document	(none)

New in v0.4.0

• 12 new write-operation tools — Now you can modify schedules directly from Claude:
  • lookup_task — Find any task by name to get its numeric ID
  • set_task_completed / set_task_completed_by_name — Mark tasks as 100% complete
  • add_dependency / remove_dependency — Manage task dependencies (prerequisites)
  • set_task_duration — Adjust task durations
  • clear_constraint_date — Remove locked/constraint dates
  • rename_task / delete_task / add_task — Structure editing
  • save_document — Persist changes to disk
• Bug fixes: .oplx parsing now prefers Actual.xml (fixes stale backup reads), outline_depth computed from hierarchy, percent-complete derived from effort-done/effort ratio, task_status computed for .oplx tasks, evaluate_javascript quotes properly escaped
• Parser robustness: build_task_tree handles both string and integer parent_ids

How It Works

.mpp file ──→ OmniPlan (AppleScript direct read) ──→ pipe-delimited records ──→ Claude
                          ↑
.oplx file ───────────────┴─── direct XML parsing ──────┘

For .oplx files

Direct XML parsing — fast, no external dependencies.

For .mpp files

1. MCP server opens the .mpp file in OmniPlan via the macOS open command
2. Reads all project data (tasks, resources, dates, progress) directly from OmniPlan's in-memory object model via AppleScript
3. Parses the pipe-delimited output into structured records
4. Closes the document

No temporary files are created — data is read directly from OmniPlan's in-memory model.
