Google Workspace MCP Server

Capable, but hard to hand over unsupervised.

Highest-value, highest-blast-radius connection in the directory: an agent that can read your mail and write your docs. The Google Cloud setup is the price of admission, and no llms.txt anywhere.

What an agent can do here

Google now ships official MCP servers for Gmail, Drive, Docs, Sheets, Slides, Calendar and Chat — the single biggest surface an agent can act on for a person.

Action depth
Core write

Agents can do the product’s core job — edit the timeline, ship the deploy, update the record.

Hosting
Self-run

You run the server process yourself.

Auth
Complex
Unattended
Needs a human

Interactive OAuth only — it cannot be provisioned without someone clicking through.

Blast radius
High

A wrong call is expensive, public, or irreversible.

What it costs to let an agent act

FreeUnmetered

Works with personal Google accounts and Workspace tenants, but requires a Google Cloud project, enabled APIs and OAuth consent. Workspace admins can block it tenant-wide.
