AI agents call list_apps to retrieve information from Frida Agent MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a simple enumeration of running applications on an Android device. It retrieves information (application list) with no side effects, state changes, or code execution. While the broader Frida Agent context involves dynamic analysis and code injection capabilities, this specific tool is a read-only query.
From the tool's definition Tool name 'list_apps' and description 'List running applications on the connected device' indicate a query operation that retrieves data about running processes without modifying or executing anything.
Documented attack patterns abuse exactly the kind of access list_apps gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Frida Agent MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for list_apps:
{
"version": "1",
"default": "deny",
"tools": {
"list_apps": {}
}
}list_apps is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List running applications on the connected device. It is categorised as a Read tool in the Frida Agent MCP MCP Server, which means it retrieves data without modifying state.
Register the Frida Agent MCP server in PolicyLayer and add a rule for list_apps: 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 Frida Agent MCP. Nothing to install.
list_apps 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 list_apps 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 list_apps. 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.
list_apps is provided by the Frida Agent MCP server (1193776794/frida-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
