Pull file from device
AI agents call pull_file_from_device to retrieve information from MCP Emulator Controller without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Pulling a file from a device is a read/fetch operation - it copies data from the device without modifying or deleting it. However, it carries medium severity because it can exfiltrate sensitive data (credentials, personal files, app data) from the device if misused by an AI agent.
From the tool's definition 'Pull file from device' - retrieves/copies a file from the device to the host; read-only operation with no modification of the source
Attacks that exploit this kind of access
Pull file from device. It is categorised as a Read tool in the MCP Emulator Controller MCP Server, which means it retrieves data without modifying state.
Register the MCP Emulator Controller MCP server in PolicyLayer and add a rule for pull_file_from_device: 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 Emulator Controller. Nothing to install.
pull_file_from_device 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 pull_file_from_device 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 pull_file_from_device. 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.
pull_file_from_device is provided by the MCP Emulator Controller MCP server (teemo4621/mcp-emulator-controller). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
