Connect Neon to Gemini Enterprise

Search, read and write Neon from Gemini Enterprise. Arlet links the two through one MCP connection and takes care of keys and authentication.

Enable Neon in ArletGemini Enterprise connection guide (docs)

Arlet makes Neon's official MCP server available from the AI client you already use. Signing in completes the connection, and you can choose read-only access at authorization.

The AI can manage projects and branches, run SQL and migrations, tune queries and read logs. Neon recommends MCP for development and testing, so for production projects choose read-only access or keep tool-call confirmation enabled in your AI client. The available tools are those provided by Neon's official server.

How to connect Neon to Gemini Enterprise

  1. 1

    In the Arlet dashboard, open Integrations → Add an integration and choose Neon. Sign in with Link Neon, name the connection and click Create.

  2. 2

    Sign in to Gemini Enterprise with your organization Google account and open the gear icon at the bottom left → Connectors → Add MCP Server.

  3. 3

    In the MCP info tab, enter https://mcp.arlet.dev/mcp/ as the Server URL and "Arlet" as the Name. In the Auth tab, enter the OAuth settings from the Arlet docs (Authorization URL / Token URL / Client ID / Client Secret / Scopes) and click Add.

  4. 4

    In the connector list on the chat screen, click Connect on Arlet, sign in with Google and authorize. Arlet can then be enabled with the toggle.

Adding custom connectors (MCP) requires a Gemini Enterprise subscription and is not available in the consumer Gemini app. See the docs for the values to enter in the Auth tab.
