Capture all UI elements and their locators for future use
AI agents call capture-ui-locators to retrieve information from MCP Appium Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads/inspects the current UI state by capturing UI elements and their locators. It is a non-destructive read operation that queries the current screen layout without modifying any state or triggering side effects.

Documented attack patterns abuse exactly the kind of access capture-ui-locators gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Appium Server, and nothing reaches the server without passing your rules. This is the rule we recommend for capture-ui-locators:
{
"version": "1",
"default": "deny",
"tools": {
"capture-ui-locators": {}
}
}capture-ui-locators is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Capture all UI elements and their locators for future use. It is categorised as a Read tool in the MCP Appium Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Appium Server MCP server in PolicyLayer and add a rule for capture-ui-locators: 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 MCP Appium Server. Nothing to install.
capture-ui-locators 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 capture-ui-locators 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 capture-ui-locators. 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.
capture-ui-locators is provided by the MCP Appium Server MCP server (rahulec08/appium-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
