FFF.GS Mail MCP. Last updated 20 August 2026.
FFF.GS Mail MCP is personal software, run by its operator on their own computer against Gmail accounts they own. It is not a hosted service. There is no account to sign up for and nothing is charged.
The source is released under the MIT Licence. It is a modified copy of shinzo-labs/gmail-mcp, also MIT.
Authorise only Gmail accounts you own or are permitted to administer. Do not use this tool to send unsolicited bulk mail or to access a mailbox without its owner's permission.
The software is provided "as is", without warranty of any kind, express or implied. The author is not liable for any claim, damages, or other liability arising from its use, including loss of mail or misdirected messages.
The tool drives a mailbox on behalf of an AI assistant. Assistants make mistakes. Review what it is about to send.
There is no uptime commitment, because there is no service. The software may change or stop working at any time, including when Google changes the Gmail API.
