AI agents call get_element_properties to retrieve information from MCP Accessibility Bridge 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 DOM elements without modifying state, triggering actions, or executing code. It is a pure read operation that queries the accessibility tree for element metadata. The low severity reflects minimal blast radius—misuse would only expose information about page structure, not perform unwanted actions or access sensitive operations.
From the tool's definition Tool returns element properties given a CSS selector ('returns the element'). The description indicates a retrieval operation with no modification capability or side effects.

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

Yes. Add a rate_limit block to the get_element_properties 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 get_element_properties. 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.
get_element_properties is provided by the MCP Accessibility Bridge MCP server (yashpreetbathla/mcp-accessibility-bridge). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP Accessibility Bridge, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
