Search the web using Tavily for the given query.
AI agents call web_search to retrieve information from Stock Analysis MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Web search is a read-only operation that retrieves publicly available data without side effects. The query parameter determines scope, but the fundamental capability is passive data retrieval. Severity is low because the impact of retrieving search results poses minimal risk even if query parameters are manipulated by an AI agent.
From the tool's definition Tool description states 'Search the web using Tavily for the given query' - a pure information retrieval operation with no modification, deletion, or execution of external operations.
Documented attack patterns abuse exactly the kind of access web_search gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Stock Analysis MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for web_search:
{
"version": "1",
"default": "deny",
"tools": {
"web_search": {}
}
}web_search is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
