Get information about the last generated/edited image in this session (file path, size, etc.). Use this to check what image is currently available for continue_editing.
AI agents call get_last_image_info to retrieve information from Nano Banana without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and retrieves metadata about previously generated images—a read-only operation with no side effects. The blast radius is minimal as it merely returns informational data about existing images without enabling changes or triggering external operations.
From the tool's definition Tool description states it retrieves information about the last generated/edited image (file path, size, etc.) with no mention of modification, deletion, or execution capabilities.
Attacks that exploit this kind of access
Get information about the last generated/edited image in this session (file path, size, etc.). Use this to check what image is currently available for continue_editing. It is categorised as a Read tool in the Nano Banana MCP Server, which means it retrieves data without modifying state.
Register the Nano Banana MCP server in PolicyLayer and add a rule for get_last_image_info: 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 Nano Banana. Nothing to install.
get_last_image_info 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_last_image_info 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_last_image_info. 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_last_image_info is provided by the Nano Banana MCP server (nano-banana-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
