Is Glean MCP server safe?

What Glean MCP server does

Glean Remote MCP Server connects Glean's enterprise knowledge, including company documents, people and data, to IDEs, LLMs and agent platforms. It is published in the gleanwork/remote-mcp-server repository; each organization has its own server URL, obtained through Glean's setup guide. It authenticates with OAuth 2.0 and SSO, and data access follows the organization's existing permissions. Before installing, confirm with your Glean administrator that the MCP server is enabled and which server URL to use, and keep in mind that content your account can see in Glean can be passed to the connected AI tool.
