Use this tool to search the web for information.
AI agents call web_search to retrieve information from MCP Server Example without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Web search queries external information sources and returns results without modifying, deleting, or executing code. This is a classic Read operation. The severity is low because search results alone pose minimal risk even if the AI agent misuses the query terms.
From the tool's definition Tool name is 'web_search' and description states 'Use this tool to search the web for information.' This is a retrieval operation with no side effects.
Attacks that exploit this kind of access
Use this tool to search the web for information. It is categorised as a Read tool in the MCP Server Example MCP Server, which means it retrieves data without modifying state.
Register the MCP Server Example 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 MCP Server Example. 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 MCP Server Example MCP server (sriharsha-gvkss/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
