The Gemini web app doesn’t support MCP at the moment, but the Gemini CLI does. However, NS AI doesn’t support the Dynamic Client Registration (DCR) flow for Gemini, so you’ll need to create the integration record yourself and provide the correct Gemini CLI redirect URL.
From there, you have two possible approaches:
1. Obtain the access token manually using Postman, and when adding MCP in the Gemini CLI, pass the token as the Bearer token.
2. If the Gemini CLI supports a proper auth flow, it will acquire the access token for you automatically.
After that, you’ll be able to use MCP in the CLI without issues.
