What Glean does in ChatGPT
The Glean plugin connects ChatGPT to Glean, a search tool that links your organization's apps and data in one place. Through Glean's remote MCP server, ChatGPT can search across all connected sources, such as documents, wikis and code repositories, and read specific documents when you need the detail.
It can also help you find people by name, role or area of expertise, read emails in Gmail and Outlook and look up details of meetings. Custom agent workflows set up in Glean let your organization automate tasks that fit how it works.
The idea is that ChatGPT and other MCP-enabled tools can use your company's context wherever you work, instead of answering from general knowledge only. What you can see depends on the sources your organization has connected to Glean and the access your account already has.
