AI agents call list_images to retrieve information from Noapi Google Search without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'list_' prefix strongly suggests a retrieval/query operation that returns a collection of images without side effects. Even though the description is empty, the consistent naming patterns across the server (archive_webpage, check_feeds, fetch_emails, get_feed_items) indicate read-only operations. No evidence suggests data modification, deletion, code execution, or financial operations.
From the tool's definition Tool named 'list_images' with no description provided. Based on naming convention matching sibling tools like 'get_feed_items' and 'archive_webpage' that perform retrieval operations, this tool appears to list or retrieve image data without modification.
Documented attack patterns abuse exactly the kind of access list_images gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Noapi Google Search, and nothing reaches the server without passing your rules. This is the rule we recommend for list_images:
{
"version": "1",
"default": "deny",
"tools": {
"list_images": {}
}
}list_images is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

list_images. It is categorised as a Read tool in the Noapi Google Search MCP Server, which means it retrieves data without modifying state.
Register the Noapi Google Search MCP server in PolicyLayer and add a rule for list_images: 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 Noapi Google Search. Nothing to install.
list_images 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 list_images 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 list_images. 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.
list_images is provided by the Noapi Google Search MCP server (vincentkaufmann/noapi-google-search-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
