WHAT IT DOES

What scrape_extract does on CoWork OS

AI agents call scrape_extract 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 scrape_extract is rated Low

This tool retrieves and extracts data from web pages with no side effects—no creation, modification, deletion, code execution, or financial transactions. It is a pure Read operation. Severity is low because web scraping has limited blast radius on local systems and cannot damage persistent data or trigger external operations.

From the tool's definition Tool name 'scrape_extract' and description 'Extract structured data from a web page. Automatically detects and extracts' indicate data retrieval/querying without modification or deletion.

RECOMMENDED RULE

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

scrape_extract Allowed

scrape_extract 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": {
    "scrape_extract": {}
  }
}

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 scrape_extract call is checked against it from then on.
