AI agents call docs_get_document to retrieve information from Google without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a query/retrieval operation on Google Docs data without creating, modifying, deleting, or executing any actions. It falls squarely into the Read category. Severity is low because unauthorized access to documents is a data confidentiality concern but does not enable destructive actions, code execution, or financial harm. The confidence is high given the clear read-only nature of the operation.
From the tool's definition Tool description states 'Get the full content of a Google Doc' — a retrieval operation with no modification or side effects. The verb 'get' and 'full content' indicate read-only access.
Attacks that exploit this kind of access
Get the full content of a Google Doc by document ID. It is categorised as a Read tool in the Google MCP Server, which means it retrieves data without modifying state.
Register the Google MCP server in PolicyLayer and add a rule for docs_get_document: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Google. Nothing to install.
docs_get_document is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the docs_get_document rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for docs_get_document. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
docs_get_document is provided by the Google MCP server (psckeithw/mcp-google). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
