Zero-shot classification for text.
AI agents call classify to retrieve information from Jina AI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Classification is a read/query operation that analyzes input text and returns a category label. It does not create, modify, delete, or execute anything — it simply returns a classification result. No side effects on external systems.

Attacks that exploit this kind of access
Zero-shot classification for text. It is categorised as a Read tool in the Jina AI MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Jina AI MCP Server MCP server in PolicyLayer and add a rule for classify: 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 MCP Server. Nothing to install.
classify 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 classify 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 classify. 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.
classify is provided by the Jina AI MCP Server MCP server (zk-armor/mcp-jina-ai). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
