How it works
Three steps from sign-in
to a working connector.
Mail Pounder handles the protocol details. You choose who you are, which Google account to use, and when to disconnect it.
- 01
Set up Mail Pounder
Your signed-in Mail Pounder identity creates the boundary for all linked accounts and grants.
- 02
Link Google
Approve Drive and Gmail access for one or more Google accounts.
- 03
Choose your client
Add Mail Pounder to ChatGPT, Claude, or Codex. Each grant snapshots its accounts, and multi-account writes require an explicit choice.
Designed for separation
Your account stays
your account.
Every MCP grant is checked against the signed-in Mail Pounder identity, and every Google API call is limited to an account linked by that same user.
Read the privacy policyEncrypted credentials
Google tokens are encrypted at rest. MCP access tokens are stored as hashes.
Optional logs
Diagnostic logging is off by default. If enabled, records are automatically deleted after seven days.
Disconnect anytime
Removing an account deletes its tokens, active grants, pending grants, and related logs.
Clear by design
Mail Pounder only uses Google data to complete the actions you request.
We do not sell Google user data, use it for advertising, or train models with it. Optional diagnostic data may include tool inputs and size-limited output excerpts for up to seven days when you explicitly enable logging.
Frequently asked
Google Workspace MCP, explained.
What Mail Pounder connects, which AI clients it supports, and how your Google accounts stay separated.
What is a Google Workspace MCP server?
A Google Workspace MCP server connects AI clients that support the Model Context Protocol to services such as Gmail, Google Drive, Docs, Sheets, and Slides. Mail Pounder exposes 38 focused tools through one hosted connection.
Can ChatGPT and Claude use Gmail and Google Drive?
Yes. After you link Google and approve a Mail Pounder connection, ChatGPT or Claude can search and read supported Workspace content and perform write actions you explicitly request.
Does Mail Pounder work with Codex?
Yes. Mail Pounder is available as a public Codex plugin with seven focused skills covering Gmail, Drive, Docs, Sheets, Slides, comments, and inbox triage.
Can I connect multiple Google accounts?
Yes. Each OAuth grant snapshots the accounts connected when you approve it. Search can span that snapshot, while writes require an explicit account whenever the grant includes more than one.
How does Mail Pounder protect Google account access?
Mail Pounder uses OAuth 2.1 with PKCE, encrypts Google credentials at rest, stores MCP access tokens as hashes, and limits each grant to accounts owned by the same signed-in identity.
Does Mail Pounder train AI models with Google data?
No. Google data is used only to complete actions you request. Diagnostic logging is off by default and, when enabled, records expire automatically after seven days.
