WHAT IT DOES

What web_search does on Azure AI Agent Service + Azure AI Search MCP Server

AI agents call web_search to retrieve information from Azure AI Agent Service + Azure AI Search MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why web_search is rated Low

Web search retrieves publicly available information without modifying, executing code, deleting data, or committing financial resources. The operation is read-only and returns search results. Severity is low because the tool's primary risk is information leakage or manipulation through search results, which has minimal blast radius when used by an AI agent.

From the tool's definition Tool name is 'web_search' and description states it 'Search[es] the web using Bing Web Grounding to find the most current information.' This is a query operation with no side effects.

RECOMMENDED RULE

The rule that runs web_search safely

web_search Allowed

web_search is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

  "default": "deny",
  "tools": {
    "web_search": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Azure AI Agent Service + Azure AI Search MCP Server, apply this rule, and every web_search call is checked against it from then on.
