WHAT IT DOES

What addSheet does on Claude MCP x Google Docs

AI agents use addSheet to create or update resources in Claude MCP x Google Docs, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Claude MCP x Google Docs environment.

RISK

Why addSheet is rated Medium

Adding a sheet is a Write-category action—it creates new structure in a spreadsheet that can be undone (the sheet can be deleted). It does not execute arbitrary code, destroy data, move money, or perform irreversible operations.

From the tool's definition Tool creates a new sheet (tab) in a spreadsheet via 'Adds a new sheet...Returns the new sheet'. This is a create operation that modifies the spreadsheet structure reversibly.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs addSheet safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Claude MCP x Google Docs, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For addSheet, this is the rule to start with:

addSheet Rate-limited

addSheet stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
