WHAT IT DOES

What browser_downloads does on CoWork OS

AI agents call browser_downloads 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_downloads is rated Low

The tool only retrieves and returns data about recent browser downloads without modifying anything. It is a passive read/query operation. Severity is low as it only exposes download history metadata, though there is some minor privacy consideration.

RECOMMENDED RULE

The rule that runs browser_downloads 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_downloads, this is the rule to start with:

browser_downloads Allowed

browser_downloads 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": {
    "browser_downloads": {}
  }
}

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_downloads call is checked against it from then on.
