AI agents call full-web-search to retrieve information from Web Search MCP Server 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 extracts publicly available web content. It has no capability to modify, delete, create, execute code, or perform financial transactions. The severity is low because web search is a standard read-only operation with no destructive blast radius on the target system or data.
From the tool's definition Tool performs 'search the web and fetch complete page content from top results' with 'extract their full page content' - pure information retrieval with no data modification, deletion, or side effects.

PolicyLayer is an MCP gateway — it sits between your AI agents and Web Search MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for full-web-search:
{
"version": "1",
"default": "deny",
"tools": {
"full-web-search": {}
}
}full-web-search is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
