Setting up Glean MCP Servers

Glean MCP Servers are fully managed and built into your Glean instance. Follow the steps below to enable Glean MCP Servers.

Enable Glean MCP Servers

1. Enable Glean OAuth authorization server.

   Navigate to the Admin Console > Settings > Third-party access (OAuth) and enable the Glean OAuth authorization server.

   
2. Enable MCP server.

   Navigate to the Admin Console > Platform > Glean MCP servers and enable the Glean MCP Servers.

   
3. Share end-user setup guide

   Provide users the end-user guide for connecting from their host application: Using the Glean MCP Server

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 → Settings → Third‑party access (OAuth).
For details, see Glean OAuth Authorization Server.
