Get top-k semantically unique images (URLs or base64-encoded) using Jina CLIP v2 embeddings and submodular optimization. Use this when you have many visually similar images and want the most diverse subset.
AI agents call deduplicate_images to retrieve information from Jina AI Remote MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and analyzes image data to produce a filtered subset, but does not create, modify, delete, or execute operations. It is a read-only operation that queries image embeddings and applies an algorithmic filter. The low severity reflects minimal blast radius if misused—an agent could waste API quota or retrieve unexpected image subsets, but cannot corrupt data or cause financial harm.
From the tool's definition Tool performs semantic deduplication of images using embeddings and submodular optimization to return a diverse subset.
Attacks that exploit this kind of access
Get top-k semantically unique images (URLs or base64-encoded) using Jina CLIP v2 embeddings and submodular optimization. Use this when you have many visually similar images and want the most diverse subset. It is categorised as a Read tool in the Jina AI Remote MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Jina AI Remote MCP Server MCP server in PolicyLayer and add a rule for deduplicate_images: 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 Jina AI Remote MCP Server. Nothing to install.
deduplicate_images 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 deduplicate_images 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 deduplicate_images. 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.
deduplicate_images is provided by the Jina AI Remote MCP Server MCP server (zhijiew/jina-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
