The .agents/plugins/marketplace.json file tells Codex where the plugin lives inside this repo. The actual plugin is under plugins/canvas-apps-codex/.

Install the plugin

Add the published marketplace repository to Codex:

codex plugin marketplace add https://github.com/justdevcode/codex-power-platform-plugins.git --ref main

Adding the marketplace only makes the plugin available. You still need to install the plugin before its skills and MCP server are available in Codex.

Start Codex and run the plugins command:

/plugins

In the plugins view:

1. Find the Power Platform Plugins marketplace.
2. Select Canvas Apps for Codex.
3. Install the plugin.

After installation, restart Codex if prompted.

Verify the installation

After installing the plugin:

/mcp

Confirm canvas-authoring is listed.

Then run:

$configure-canvas-mcp

Open the target Canvas App in Power Apps Studio, then provide the Power Apps Studio URL when prompted.

Source and attribution

The plugin is adapted from Microsoft's Power Platform skills repository:

It also references the earlier Codex port by Ratnam Mishra:
