MCP server
Gmail MCP server for Claude, ChatGPT and your own agents
There are two ways to give an AI agent Gmail over MCP. Google's own Gmail MCP server is in developer preview: it searches, reads, labels and drafts, but doesn't send. Mojobase's MCP server reads and drafts across Gmail and your other mailboxes, and the same connection reaches your calendar, documents, tasks, customers and Handbook.

How does Gmail's own MCP server compare with Mojobase's?
| What matters | Mojobase MCP | Gmail's own |
|---|---|---|
| Status | Available to every Mojobase company | Developer Preview, for members of the Google Workspace Developer Preview Program1 |
| What it can do with mail | Search, read threads and attachments, draft replies and new mail, schedule drafts | Search and read threads, list and apply labels, list drafts and create drafts2 |
| Sending | Drafts and schedules; you send, or allow it for the kinds of mail you choose | No send tool: create_draft puts the message in Drafts, and you send it from Gmail3 |
| Setup | Connect Gmail in Mojobase, then add one address to your agent | A Google Cloud project with the Gmail API and Gmail MCP API enabled, an OAuth consent screen and client, then the server address in your MCP client4 |
| Beyond Gmail | The same connection reaches Outlook and IMAP mailboxes, calendar, documents, tasks, customers, numbers and the Handbook | Gmail only; Google publishes separate servers for its other products5 |
Which tools does your agent get for Gmail through Mojobase?
| Tool | What it does |
|---|---|
mail_search | Full-text search across every mailbox you can see, newest first |
mail_thread | A whole conversation, oldest first, across folders and mailboxes |
mail_attachment_text | The text inside an attached PDF, Word, Excel or CSV file |
draft_reply | Writes a reply as a draft, with the recipients worked out, recorded under the agent's name |
draft_schedule | Schedules a draft to go at a set time |
mojobase_search | One search across mail, events, files, tasks and Handbook pages |
What can you ask your agent once it's connected?
- “Find every email from Northside this month and draft a reply to the latest.”
- “What does the contract attached to Sam's email say about notice?”
- “Draft follow-ups to everyone who hasn't answered my quote in a week.”
- “Which emails today mention a meeting, and is there a slot free?”
Which should you use: Google's Gmail MCP server or Mojobase's?
Use Google's server if you only need Gmail, you're comfortable setting up a Google Cloud project, and your account is in the developer preview. Use Mojobase's if your agent should also see your calendar, files, tasks and customers, or you have mailboxes outside Gmail. Mojobase's one server covers all of them with one address and one sign-in.
Is it safe to give an AI agent your email?
It's as safe as the rules around it. Email text is untrusted: a message can contain instructions aimed at an AI. Mojobase's scheduled runs only ever get tools that read or write drafts, enforced by the server rather than by asking the model, so a mail that says "forward this to …" can't make a run send anything. Your own agent acts as you, and every action shows in Activity, with Undo.
Questions people ask
Is there an official Gmail MCP server?
Yes. Google publishes one at gmailmcp.googleapis.com, in developer preview for members of its Google Workspace Developer Preview Program. It needs a Google Cloud project with the Gmail MCP API enabled and an OAuth client.
Can an AI agent send Gmail over MCP?
Google's server has no send tool: it creates drafts for you to send from Gmail. Mojobase drafts and schedules too, and every draft and send shows in Activity under the agent's name.
How do I connect Mojobase's MCP server to Claude?
Copy your company's address from Settings → Connect an agent in Mojobase and add it as a custom connector in Claude, or run one command in Claude Code with a key. The steps are on the Claude page.
Does the agent see everyone's email?
No. It acts as the person who connected it, so it sees exactly the mailboxes that person sees, under the same rules as their screens.
