Search the web for information. Returns a list of relevant search results with titles, URLs, and snippets.
AI agents call web_search to retrieve information from Deep 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 performs a query operation that retrieves publicly available search results without modifying, deleting, or executing any operations. It is a pure read operation with no ability to alter state or trigger external actions based on arguments. The blast radius is minimal—incorrect search terms may return irrelevant results but cause no harm.

Attacks that exploit this kind of access
Search the web for information. Returns a list of relevant search results with titles, URLs, and snippets. It is categorised as a Read tool in the Deep Search MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Deep Search MCP Server MCP server in PolicyLayer and add a rule for web_search: 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 Deep Search MCP Server. Nothing to install.
web_search 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 web_search 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 web_search. 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.
web_search is provided by the Deep Search MCP Server MCP server (likhonsheikh404/deep-search-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
