Google Workspace MCP: five ways to connect Gmail, Drive and Calendar

Q: Can Claude send email from my Gmail?

Claude's directory page for the Gmail connector lists sendmessage, reply and forward among its 29 tools. Google's own reference page for the same server lists 10 tools and none that sends. Can ChatGPT and Claude send emails covers the other ways.

Q: Which Google Workspace MCP server has the most tools?

Of the ones here, the community project googleworkspacemcp, which describes more than 120 tools across twelve services. Claude's Gmail connector lists 29.

Google runs its own MCP servers for Gmail, Google Drive and Google Calendar. Claude's directory has listed them since March 2026, and developers can connect to them directly through a Developer Preview. On November 10, 2026, we counted 214 servers in the official MCP Registry that work with Google Workspace, and none of them is published by Google. Below are the five ways to connect, what each one can do and what each one needs from you.

Five ways at a glance

Way	Who makes it	What you set up	Tools
Google's connectors in Claude	Google	Add Gmail, Google Calendar or Google Drive from Claude's directory and sign in	29 for Gmail, 9 for Calendar, 11 for Drive^3,4,5
Google's servers, connected yourself	Google	Developer Preview membership, a Google Cloud project and an OAuth client	10 for Gmail on Google's reference page^1,2
ChatGPT's connected apps	OpenAI	Connect the app in ChatGPT	OpenAI's help center names Google Drive and Gmail among them¹¹
A community server	A developer on GitHub	Run it yourself with your own Google Cloud OAuth client	Up to 120 in one server⁷
Conecto (ours)	Conecto	A service account that your Workspace admin approves	11 across mail, calendar and Drive¹²

The first way is the shortest. The other four exist because of what it leaves out: an agent that isn't Claude, a whole company's mailboxes behind one connection, or control over which permissions the agent gets.

What Google itself ships

Google Workspace has remote MCP servers, one for each product: Gmail, Google Drive, Google Docs, Google Sheets, Google Slides, Google Calendar, Google Chat, the People API and Google Classroom. Google's guide says they let AI applications "like Google Antigravity and Claude" read data and take actions, with the same permissions the user has.¹

They are a Developer Preview. To connect to them yourself, Google's guide asks for four things:

Membership in the Google Workspace Developer Preview Program.
A Google Cloud project, with each product's API and its MCP service switched on.
An OAuth consent screen and an OAuth client that has "Use this client for an AI-powered agent" selected.
An MCP client.¹

The Gmail server's address is https://gmailmcp.googleapis.com/mcp/v1.² Claude's directory gives the same pattern for the other two, calendarmcp.googleapis.com and drivemcp.googleapis.com.^4,5 For Gmail, Google's guide asks for two permissions, one to read mail and one to compose it.¹

One Gmail server, two tool lists

This is the part we did not expect. Google's reference page for the Gmail server and Claude's directory page for the Gmail connector name the same address, and they list different tools.

	Google's reference page	Claude's directory page
Tools listed	10²	29³
Read and search	get_message, get_thread, search_threads, list_drafts, list_labels	The same five, and list_filters
Write a draft	create_draft	create_draft
Send	None	send_message, reply, forward
Labels	Add or remove a label on a message or a thread	The same, and create_label, delete_label
Spam, trash and filters	None	Mark as spam, move to trash, create_filter

On Google's page, the furthest an agent goes is a draft. Its own test prompt says the client "uses gmail.create_draft to create an email in your drafts folder, allowing you to review and send it from Gmail."¹ On Claude's page, the connector can send, reply and forward.³

Google's reference page was last updated on July 21, 2026, so it may be behind the server. We read both pages on November 11, 2026. We did not connect either one to a mailbox, so we can't say which list a given account gets. If sending matters to you, list the tools after you connect and before you rely on it.

What Claude's three Google connectors can do

All three are made by Google, verified by Anthropic and in the directory since March 2026.

Connector	Tools	What they cover
Gmail	29	Search and read threads, draft, send, reply, forward, labels, filters, spam and trash³
Google Calendar	9	List calendars and events, search, suggest a time, create, update and delete events, answer an invitation⁴
Google Drive	11	Search, read and download files, create, copy and update them, share, read permissions, move to trash⁵

Each one connects one person's Google account to that person's Claude. Claude connectors has the steps for adding one, and the best Claude connectors lists the rest of the directory by job.

How many Google Workspace MCP servers there are

We went through every server in the official MCP Registry on November 10, 2026. Of its 60,115 active servers, 214 name Gmail, Google Drive, Google Calendar, Google Docs, Sheets, Slides, Meet or Google Workspace in their name, title or description.⁶

Servers that name	Count
Gmail	100
Google Docs or Sheets	48
Google Workspace as a whole	27
Google Drive	25
Google Calendar	20

A server that names two products counts in both rows. Of the 214, 101 are remote servers at a web address and 123 are packages you install and run. Twelve are both.

Google publishes 15 servers of its own in the registry, for products such as Compute Engine, Firestore, Cloud Run and Maps. None of the 15 is for Gmail, Drive or Calendar.⁶ So every one of the 214 comes from someone other than Google, and the registry alone won't lead you to Google's own Workspace servers.

The full count of the registry is on our statistics page.

The community servers people use most

These are the four most starred projects we found on GitHub for Google Workspace and Gmail, read on November 11, 2026.

Project	Stars	License	Last change	Covers
google_workspace_mcp, by taylorwilsdon	3,506	MIT	November 11, 2026	Twelve Workspace services and more than 120 tools, by its own description⁷
Gmail-MCP-Server, by GongRzhe	1,169	MIT	August 6, 2025	Gmail⁸
google-docs-mcp, by a-bonus	686	MIT	October 26, 2026	Docs, Sheets, Drive, Gmail and Calendar⁹
google-workspace-mcp, by aaronsb	195	Apache 2.0	November 10, 2026	Gmail, Calendar and Drive¹⁰

The largest one says plainly what it needs: your own OAuth client from the Google Cloud Console, in a project with the Google APIs switched on. In return, it says your credentials never leave your environment and you control the permissions.⁷

Stars show interest. They are not a review of the code. One of the four has not changed since August 2025.⁸ What to check before you connect a server applies to all of them.

Where Conecto fits

Conecto is our product, and it connects Google Workspace in a different way from the four above. The connection belongs to the company, not to one person. Your business makes a service account in Google Cloud, and your Workspace admin approves it for Gmail, Calendar and Drive. You then name the mailboxes your agent may act as, from 1 to 20, and it never acts as anyone else.¹³

It has 11 tools: search, read and send mail, read, add and cancel calendar events, search and read Drive files, and write a text file to Drive. Reading and searching are free. Each email sent, event added or cancelled, or file written costs $0.001.¹²

Three limits to know:

It needs a Workspace admin, so it does not work with a personal gmail.com account.¹³
It reads Drive files up to 5 MB and writes text files only.¹²
Cancelling an event and replacing a file wait for the owner's approval by default.¹³

The same connection gives your agent Conecto's other tools, such as a CRM and invoices, next to your Google mail. If one person wants Claude to read their own inbox, Google's connector in Claude is the shorter way.

Which one fits

You use Claude and want your own Gmail, Calendar and Drive in it: Google's three connectors in Claude's directory.^3,4,5
You use ChatGPT: its connected apps. ChatGPT connectors explains where they are and what a custom MCP server adds.¹¹
You are a developer building your own agent: Google's servers through the Developer Preview, or a community server if you want to run and change the code yourself.^1,7
Your agent should work as support@ or sales@ for the whole company: a connection the company owns, such as Conecto's.¹³

Microsoft's side of the same question is in Microsoft 365 MCP.

How we counted

For the registry count, we read every entry of the official MCP Registry through its public API on November 10, 2026, counted each server name once at its latest active version, and searched each name, title and description for the eight product names above.⁶ A server that mentions Gmail only in passing still counts, so 214 is the widest fair number. The narrow one is 73: the servers that carry a Google Workspace product in their name.

For the tool lists, we read Google's reference page and Claude's three directory pages on November 11, 2026, and copied the tool names as printed. For the community table, we took stars, licenses and the date of the last change from GitHub on the same day.

We did not connect any of these to a real mailbox, and we did not test what each tool does. This guide compares what each maker publishes.

Questions

Does Google have an official MCP server for Gmail?

Yes. Google runs a Gmail MCP server at gmailmcp.googleapis.com, with one each for Drive, Calendar, Docs, Sheets, Slides, Chat, the People API and Classroom. They are a Developer Preview.^1,2

Can Claude send email from my Gmail?

Claude's directory page for the Gmail connector lists send_message, reply and forward among its 29 tools.³ Google's own reference page for the same server lists 10 tools and none that sends.² Can ChatGPT and Claude send emails covers the other ways.

How many Google Workspace MCP servers are there?

We counted 214 in the official MCP Registry on November 10, 2026, out of 60,115 active servers. Gmail is named most often, by 100 of them.⁶

Does a Google Workspace MCP server work with a free Gmail account?

It depends on the route. Conecto's needs a Workspace admin, so it doesn't.¹³ Google's developer route needs membership in its Developer Preview Program.¹ We did not test Claude's connectors with a personal account.

Which Google Workspace MCP server has the most tools?

Of the ones here, the community project google_workspace_mcp, which describes more than 120 tools across twelve services.⁷ Claude's Gmail connector lists 29.³

Is Google's Workspace MCP server in the official MCP Registry?

No. Google lists 15 of its own servers there, all for cloud and developer products, and none for Gmail, Drive or Calendar.⁶
