WHAT IT DOES

What pre-browse does on Claude Flow

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

RISK

Why pre-browse is rated Low

This tool retrieves recommendations (a Read operation) prior to browser automation, with no side effects or capability to modify, execute, or delete data. The phrasing 'get recommendations' is explicitly a query/retrieval operation. Severity is low because misuse would only expose advice or suggestions, not trigger destructive automation.

From the tool's definition Tool name 'pre-browse' and description 'Get recommendations before browser automation' indicate a read-only advisory function that retrieves or queries recommendations without performing actions.

RECOMMENDED RULE

The rule that runs pre-browse safely

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

pre-browse Allowed

pre-browse 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": {
    "pre-browse": {}
  }
}

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

The button opens the PolicyLayer dashboard: create your workspace, connect Claude Flow, apply this rule, and every pre-browse call is checked against it from then on.
