canvas-apps-plugin-codex

Power Apps Canvas Apps development with Codex CLI — adapted from Microsoft's power-platform-skills canvas-apps plugin.

This repository is now packaged as a local Codex plugin via .codex-plugin/plugin.json.

Microsoft's official canvas-apps plugin was built for Claude Code.
This is a port for ChatGPT Codex CLI — giving you the same
Power Apps generation workflow with significantly more usage per
session on the Plus plan.

Quick Start

1. Install Prerequisites

• .NET 10 SDK
• PAC CLI
• Codex CLI

2. Install the Local Plugin

Install or link this directory as a local Codex plugin. The plugin manifest is at .codex-plugin/plugin.json, and the public entrypoints are the $... skills in skills/.

3. Open Your Canvas App in Power Apps Studio

1. Go to make.powerapps.com
2. Open your canvas app in the designer
3. Enable coauthoring: Settings → Updates → Coauthoring → ON
4. Copy the full URL from your browser

4. Configure the MCP Server

Then run:

$configure-canvas-mcp

Paste your Studio URL when prompted. Restart Codex after configuration.

5. Generate or Edit Apps

New app:

$generate-canvas-app Create a canvas app for tracking employee leave requests

Edit existing app:

$edit-canvas-app Add a dark mode toggle to the settings screen

Add a data source:

$add-data-source I need to connect to a SharePoint list called "Projects"

What Gets Generated

Each app is written as .pa.yaml files in a subfolder named after your app. These files are validated by the Canvas Authoring MCP server and auto-synced to your live Power Apps Studio session.

Status

This is an adaptation of Microsoft's canvas-apps plugin (preview) for use with Codex CLI. The core workflow remains the same; this repository now exposes the workflow through plugin-packaged Codex skills.
