This tool performs reconnaissance by crawling and enumerating links on a website, which is a read-only operation with no side effects. It retrieves structural information about a target site but does not execute code, modify data, or trigger external actions. The blast radius is minimal—misuse would allow an AI to enumerate a site's structure, but cannot cause harm beyond information disclosure.

PolicyLayer is an MCP gateway — it sits between your AI agents and ReActMCP Web Search, and nothing reaches the server without passing your rules. This is the rule we recommend for map_website:
{
"version": "1",
"default": "deny",
"tools": {
"map_website": {}
}
}map_website is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
