AI agents call get_presentation to retrieve information from Gg without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves and queries presentation metadata and content. It does not create, modify, delete, or execute operations. The action is read-only with no side effects, making it a Read category risk. Severity is low because retrieving presentation content has minimal blast radius; the primary risk is unauthorized information access, which is mitigated by Google Workspace's access controls.
From the tool's definition Tool description states 'Get metadata and slide titles/content from a Google Slides presentation' — uses 'Get' verb and retrieves existing data without modification.
Attacks that exploit this kind of access
Get metadata and slide titles/content from a Google Slides presentation. It is categorised as a Read tool in the Gg MCP Server, which means it retrieves data without modifying state.
Register the Gg MCP server in PolicyLayer and add a rule for get_presentation: 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 Gg. Nothing to install.
get_presentation 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 get_presentation 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 get_presentation. 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.
get_presentation is provided by the Gg MCP server (tannht/google-cloud-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
