antigravity-notebooklm

Connect NotebookLM (AntiGravity version)

Steps

1. Install

uv tool install notebooklm-mcp-cli
nlm --version

2. Log in

Ask the user to run it themselves in a normal, visible PowerShell window (do not repeatedly run it in the AntiGravity background terminal):

$env:PYTHONUTF8 = '1'
nlm config set auth.browser chrome
nlm login --profile default

(This opens a separate Chrome window managed by nlm ; select the correct Google account to complete login. This is a third-party CLI session login, not AntiGravity's MCP OAuth button.)

3. Verify

nlm doctor
nlm list

If Windows has a CP950 encoding error: first run $env:PYTHONUTF8 = '1' then run it again

4. Register MCP

First give advance notice that the AntiGravity MCP settings will be modified and get confirmation, then use the built-in AntiGravity settings command in nlm :

$env:PYTHONUTF8 = '1'
nlm setup add antigravity

The settings will be written to the workspace .agents/mcp_config.json or the global ~/.gemini/config/mcp_config.json. After completion, restart AntiGravity or use /mcp to reload, then ask it to list the number of notebooks to verify.

If there is already a command server pointing to notebooklm-mcp , do not run it again to avoid duplication.
The older "command": ["nlm", "mcp"] is the OpenCode opencode.json syntax and does not apply to AntiGravity 2.

⚠️ Do not copy cookies/tokens, and do not commit the notebook list to the repo.
