AI agents call get-page-source 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 retrieves and returns data about the current UI state in XML format. It has no side effects, does not modify application state, does not execute commands, and does not delete or move data. It is a pure information-gathering operation, making it a Read category tool with low severity.
From the tool's definition Tool name 'get-page-source' and description 'Get the XML representation of the current UI' indicate a retrieval operation that reads the current state of the mobile application interface without modifying or executing actions.
Documented attack patterns abuse exactly the kind of access get-page-source 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 get-page-source:
{
"version": "1",
"default": "deny",
"tools": {
"get-page-source": {}
}
}get-page-source is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get the XML representation of the current UI. 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 get-page-source: 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.
get-page-source 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 get-page-source 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-page-source. 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-page-source 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.
