Set up the Glean plug-in in Codex

Install the Glean plug-in, connect your organization's Glean MCP server, and authenticate from Codex.

Prerequisites

Ask your Glean administrator to complete the Glean plug-in prerequisites.

Install and connect the plug-in

1. Open the Glean MCP configurator and copy your organization's server address and server name.

2. Add the Glean marketplace and install the plug-in:

   codex plugin marketplace add gleanwork/codex-plugins
   codex plugin add glean@glean-codex-plugins

3. Connect and authenticate the Glean MCP server. Substitute the server address and name from the configurator:

   codex mcp add glean --url <server-url>/mcp/<server-name>
   codex mcp login glean

4. Start a new Codex task so the bundled Glean Skills and MCP tools are available.

For current Codex-specific requirements and commands, see Glean Plugin for Codex on the Developer Portal.

Verify the setup

Start a new Codex task and ask:

Search for my company onboarding docs in Glean.

Setup is complete when the bundled Glean Skills and MCP tools are available and the search succeeds.
