How OAuth fits

Enabling the Glean OAuth authorization server unlocks OAuth‑based authentication for MCP:

• Dynamic clients (DCR) – MCP hosts (such as Cursor, Claude, VS Code) discover Glean at runtime and register themselves using OAuth Dynamic Client Registration.
• Static OAuth clients – Admin‑managed OAuth applications with stable client IDs and redirect URIs, used for specific integrations or external MCP servers that require a fixed client configuration.

You can view and manage these OAuth clients in Admin Console → Users & permissions → Third‑party access (OAuth).
For details, see Glean OAuth Authorization Server.
