Coreader for Codex

Install for Codex

The simplest way is to copy the request below and send it to your AI. If you prefer the terminal, the official commands are here too.

1. Install the plugin

Ask AI to install it

Send this prompt to your AI. You still complete the OAuth login and consent yourself.

Please install the official Coreader plugin.

Official repository: https://github.com/vzheng56/coreader-plugins

Run:
1. codex plugin marketplace add vzheng56/coreader-plugins
2. codex plugin add coreader@coreader

If Coreader opens an authorization page, let me complete the sign-in and confirmation in my browser. After installation, remind me to start a new Codex task and use Coreader to show what I have read recently.
I want to run the commands myself

Run in your terminal

codex plugin marketplace add vzheng56/coreader-plugins
codex plugin add coreader@coreader

Authorize and verify

2

Start OAuth

On first use, the client asks you to sign in and authorize Coreader in your browser.

3

Review scopes

Confirm the client and the read/write access it requests, then decide whether to connect.

4

Reload the client

Start a new Codex task after installation so the plugin, Skill, and MCP tools load cleanly.

5. Verify the connection

Send this prompt to your client. If your books are returned, installation and OAuth are complete.

@coreader What have I read recently?

Update, uninstall, and manage access

Update the plugin

Update commands

codex plugin marketplace upgrade coreader
codex plugin add coreader@coreader

Uninstall the plugin

Uninstalling does not automatically revoke OAuth. Revoke the connection separately.

Uninstall command

codex plugin remove coreader@coreader
Open My AI

No tools, or seeing invalid_grant?

  1. 1. Remove the existing Coreader plugin or connection from the client.
  2. 2. Revoke the old authorization on the connections page.
  3. 3. Run the install commands again and complete a fresh OAuth flow.
  4. 4. Start a new session and send the verification prompt again.
The official plugin only connects to https://mcp.coreader.dev/mcp and contains no user credentials.
