WHAT IT DOES

What web_search does on Martin MCP Toolbox

AI agents call web_search to retrieve information from Martin MCP Toolbox 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

This tool performs web search and returns results—a read-only operation with no modification, deletion, or external command execution. The description explicitly states it returns 'raw search results' without automatic composition, confirming it is a passive information retrieval function. Blast radius is minimal as misuse would only expose retrieved public information.

From the tool's definition Tool name 'web_search' and description stating '快速检索并返回原始搜索结果' (rapidly retrieve and return raw search results) indicates data retrieval without side effects or content generation.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs web_search safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Martin MCP Toolbox, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For web_search, this is the rule to start with:

web_search Allowed

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

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "web_search": {}
  }
}

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

The button opens the PolicyLayer dashboard: create your workspace, connect Martin MCP Toolbox, apply this rule, and every web_search call is checked against it from then on.
