Capture accessibility snapshot of the current page.
AI agents call browser_snapshot to retrieve information from Camoufox without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about the current page state (accessibility snapshot) without creating, modifying, deleting, or executing operations on the page. It is a read-only operation that captures existing page content for inspection purposes. The low severity reflects minimal risk—an AI agent misusing this would only be able to view page information, not alter systems or trigger side effects.
From the tool's definition Tool name 'browser_snapshot' and description 'Capture accessibility snapshot of the current page' indicate data retrieval with no modifications.
Documented attack patterns abuse exactly the kind of access browser_snapshot gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Camoufox, and nothing reaches the server without passing your rules. This is the rule we recommend for browser_snapshot:
{
"version": "1",
"default": "deny",
"tools": {
"browser_snapshot": {}
}
}browser_snapshot is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Capture accessibility snapshot of the current page. It is categorised as a Read tool in the Camoufox MCP Server, which means it retrieves data without modifying state.
Register the Camoufox MCP server in PolicyLayer and add a rule for browser_snapshot: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Camoufox. Nothing to install.
browser_snapshot is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the browser_snapshot rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for browser_snapshot. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
browser_snapshot is provided by the Camoufox MCP server (rlgrpe/camoufox-mcp-python). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Camoufox, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
