Glean Plugins for Codex
Installation
1
Get your Glean MCP server details
The glean plugin requires a Glean MCP connection. Open the Glean MCP configurator to find your organization's server URL and server name — you'll use both in the last step.
Open MCP Configurator2
Add the Glean marketplace and install plugins
Run these commands in your terminal. glean is the enterprise-knowledge plugin; glean-dev-docs adds search over Glean's developer documentation.

3
Connect the MCP servers
Before starting Codex, connect the MCP server each plugin uses — substitute the server URL and name from step 1. Then start a new Codex task so the bundled skills and MCP tools are available.
Glean enterprise knowledge
codex mcp add glean --url <server-url>/mcp/<server-name> codex mcp login glean
Glean developer docs
codex mcp add glean-dev-docs --url https://developers.glean.com/mcp
