WHAT IT DOES

What browser_network does on CoWork OS

AI agents call browser_network to retrieve information from CoWork OS 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_network is rated Low

This tool reads and returns browser network traffic data. While secrets are redacted, it still exposes potentially sensitive metadata about URLs visited, request patterns, and response data. It has no write/execute side effects — it only retrieves existing network log data. The medium severity reflects the privacy risk of exposing browsing activity and network patterns to an AI agent.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs browser_network safely

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

browser_network Allowed

browser_network 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_network": {}
  }
}

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

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