WHAT IT DOES

What browser_tabs does on Freshdesk

AI agents call browser_tabs to retrieve information from Freshdesk without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why browser_tabs is rated Low

The tool retrieves information about open browser tabs and allows navigation between them. Neither listing nor switching tabs creates, modifies, deletes, or executes arbitrary operations. This is a read-class tool with minimal blast radius if misused by an AI agent.

From the tool's definition Tool description states 'List open tabs or switch to a tab by number' — listing is a read operation; switching to a tab is a state navigation action without data modification or code execution.

RECOMMENDED RULE

The rule that runs browser_tabs safely

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

browser_tabs Allowed

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

policy.json

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

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

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