Load an image from disk and return it as PNG to the chat.
AI agents call image_show to retrieve information from farshid-mcp-imageProcessing without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads image data from disk and returns it for display. It performs no writes, deletions, code execution, or financial operations. The only potential risk is that an attacker could use it to exfiltrate sensitive image files if file path inputs are not restricted, but the tool itself is fundamentally a read operation. Classified as Read with low severity.
From the tool's definition Tool description states 'Load an image from disk and return it as PNG to the chat' — a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
Load an image from disk and return it as PNG to the chat. It is categorised as a Read tool in the farshid-mcp-imageProcessing MCP Server, which means it retrieves data without modifying state.
Register the farshid-mcp-imageProcessing MCP server in PolicyLayer and add a rule for image_show: 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 farshid-mcp-imageProcessing. Nothing to install.
image_show 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 image_show 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 image_show. 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.
image_show is provided by the farshid-mcp-imageProcessing MCP server (pirahansiah/farshid-mcp-imageprocessing). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
