Why browser_get_interaction_map needs a policy

This tool queries the state of interactive elements on a webpage to provide navigation information for the caller. It reads the DOM structure and returns selector hints without performing any actions, clicking, navigation, or data modification.

From the tool's definition Tool returns a map of interactive elements with selector hints - purely informational/retrieval operation with no side effects. The description explicitly indicates data retrieval ('Return') rather than execution or modification.

POLICY

How to control browser_get_interaction_map

PolicyLayer is an MCP gateway — it sits between your AI agents and Web Scraper, and nothing reaches the server without passing your rules. This is the rule we recommend for browser_get_interaction_map:

policy.json

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

browser_get_interaction_map is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Web Scraper — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
