What Gemini CLI can do in WhatsApp

Each action can be turned off per account, and changes can wait for your OK.

Action	Access
List chats WhatsApp chats, most recent first, with unread counters.	Reads
Search messages Searches all chats or one chat by words, sender and dates.	Reads
Read a chat Latest messages of a chat; page back for older ones.	Reads
What's new New messages since the last check, without repeats.	Reads
Send a message Writes to a chat through a queue: human-like pauses and typing, never twice. Files can be attached by link. A first message to someone new needs your OK.	Risky
Mark as read Marks every message of a chat as read.	Makes changes
Attachment Downloads a file from a message; the AI can look at photos and listen to voice messages.	Reads
Message templates Approved templates of the number and their variables.	Reads
Send a template Writes with a template when 24 hours have passed or the person has not written yet. Same queue; to someone new only with your approval.	Risky

Questions

Can I connect two WhatsApp accounts to Gemini CLI?

Yes. Connect each one in Manyplug under its own name, for example Work and Personal. Gemini CLI can use one of them or all at once.

Will Gemini CLI change anything in WhatsApp without asking?

By default these actions wait for your approval before they run: “Send a message” and “Send a template”. Other changes follow your rules, which you can make stricter per account.

Do I need an official WhatsApp MCP server for this?

No. Manyplug connects to WhatsApp itself with a key or app password you paste into its form, and gives Gemini CLI the tools through one MCP address, together with your other services.

Is it free to connect Gemini CLI to Manyplug?

Yes. New workspaces get 14 days of Pro free, then the free plan keeps going with 150 actions a month and up to 3 connected accounts. No card needed. Paid plans start at $5 a month.

Does Gemini CLI see my passwords or API keys?

No. Keys are entered on Manyplug’s own pages, stored encrypted with a separate key per account, and the AI only receives tool results.
