AI agents call get_form_response 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 and queries form response data from Google Forms without modifying, deleting, or executing any operations. It is a straightforward read operation that returns existing data. The blast radius of misuse is minimal—an attacker could read form responses but cannot modify forms, trigger actions, or cause destructive changes. Low severity reflects the read-only nature and limited impact.
From the tool's definition Tool name 'get_form_response' and description 'Get a single response from a Google Form' indicate retrieval of data with no side effects.

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_form_response:
{
"version": "1",
"default": "deny",
"tools": {
"get_form_response": {}
}
}get_form_response is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get a single response from a Google Form. 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_form_response: 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_form_response 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_form_response 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_form_response. 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_form_response 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.
