Show statistics about the output directory and recently generated images.
AI agents call show_output_stats to retrieve information from Banana Image MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only reads and displays statistics about existing outputs and generated images. It has no capability to modify, delete, execute code, or trigger external operations. It is a simple informational/reporting function with no side effects, making it a Read category tool with low severity.
From the tool's definition Tool name is 'show_output_stats' and description states it 'Show statistics about the output directory and recently generated images.' This retrieves and displays information only.
Documented attack patterns abuse exactly the kind of access show_output_stats gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Banana Image MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for show_output_stats:
{
"version": "1",
"default": "deny",
"tools": {
"show_output_stats": {}
}
}show_output_stats is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Show statistics about the output directory and recently generated images. It is categorised as a Read tool in the Banana Image MCP MCP Server, which means it retrieves data without modifying state.
Register the Banana Image MCP server in PolicyLayer and add a rule for show_output_stats: 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 Banana Image MCP. Nothing to install.
show_output_stats 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 show_output_stats 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 show_output_stats. 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.
show_output_stats is provided by the Banana Image MCP server (zengwenliang416/banana-image-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Banana Image MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
