Product Partner Support

While there is no formal partner program yet, Glean is building MCP Host Application and MCP Server functionality to support integration with third-party MCP servers. Interested partners should contact the Glean partnerships team.

​
Considerations

Advanced Authentication. With MCP host applications that don’t support OAuth, do not involve a user in the authentication process, or require manual authentication, you can use user-scoped Client API tokens. The tokens require the following scopes: MCP, AGENT, SEARCH, CHAT, DOCUMENTS, TOOLS, and ENTITIES. User Session Management. Your Admin can continue to sign a user out of all sessions — including those from MCP host applications — via the Glean Admin UI. Privacy and Data Protection. The Remote MCP Server inherits Glean platform privacy guarantees and is covered under Glean’s Data Processing Addendum (DPA). All queries enforce user permissions via Glean’s Knowledge Graph.
