AI agents call get_presentation to retrieve information from VaultAssist without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about a presentation without creating, modifying, deleting, or executing any operations. It is a read-only query operation with minimal blast radius if misused by an AI agent—the worst outcome would be unauthorized data access to presentation metadata, which is a confidentiality concern but not destructive or operational.
From the tool's definition Tool name is 'get_presentation' and description states 'Get details about a Google Slides presentation'. The verb 'Get' and phrase 'details about' indicate data retrieval with no modification or side effects.
Documented attack patterns abuse exactly the kind of access get_presentation gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and VaultAssist, and nothing reaches the server without passing your rules. This is the rule we recommend for get_presentation:
{
"version": "1",
"default": "deny",
"tools": {
"get_presentation": {}
}
}get_presentation is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get details about a Google Slides presentation. It is categorised as a Read tool in the VaultAssist MCP Server, which means it retrieves data without modifying state.
Register the VaultAssist 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 VaultAssist. 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 VaultAssist MCP server (3xcaffeine/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from VaultAssist, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
