Performs a web search using Google, ideal for finding current information, news, websites, and general knowledge. Use this tool when you need to research topics, find recent information, or gather data from the web. Returns structured search results with titles, URLs, and snippets.
AI agents call search_google to retrieve information from MCP Web Research Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information from the web without creating, modifying, deleting, or executing code. It is a pure read operation that queries Google's search engine and returns results. The blast radius of misuse is minimal—an agent could perform unwanted searches but cannot modify data, execute commands, or access restricted information beyond what Google search publicly returns.
From the tool's definition Tool performs 'web search using Google' and 'returns structured search results with titles, URLs, and snippets.' The verb 'performs a web search' and the description of return values (titles, URLs, snippets) indicate data retrieval with no modification or…
Documented attack patterns abuse exactly the kind of access search_google gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Web Research Server, and nothing reaches the server without passing your rules. This is the rule we recommend for search_google:
{
"version": "1",
"default": "deny",
"tools": {
"search_google": {}
}
}search_google is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Performs a web search using Google, ideal for finding current information, news, websites, and general knowledge. Use this tool when you need to research topics, find recent information, or gather data from the web. Returns structured search results with titles, URLs, and snippets. It is categorised as a Read tool in the MCP Web Research Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Web Research Server MCP server in PolicyLayer and add a rule for search_google: 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 MCP Web Research Server. Nothing to install.
search_google 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 search_google 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 search_google. 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.
search_google is provided by the MCP Web Research Server MCP server (phialsbasement/mcp-webresearch-stealthified). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP Web Research Server, 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.
