Classify texts into user-defined labels using Jina embeddings. Use this when you need to categorize, tag, or sort text content into predefined categories. Perfect for sentiment analysis, topic classification, content moderation, or any text categorization task.
AI agents call classify_text 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.
classify_text retrieves semantic information from text via embedding-based classification and returns categorization results. It has no side effects on data or external systems—it only reads text input and produces categorical labels. This is purely informational and matches the Read category definition of retrieving or querying data without side effects.
From the tool's definition Tool performs text classification using embeddings against user-defined labels. Description indicates it 'categorize[s], tag[s], or sort[s] text content' and gives examples: 'sentiment analysis, topic classification, content moderation'.
Documented attack patterns abuse exactly the kind of access classify_text gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Jina AI Remote MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for classify_text:
{
"version": "1",
"default": "deny",
"tools": {
"classify_text": {}
}
}classify_text is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Classify texts into user-defined labels using Jina embeddings. Use this when you need to categorize, tag, or sort text content into predefined categories. Perfect for sentiment analysis, topic classification, content moderation, or any text categorization task. 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 classify_text: 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.
classify_text 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_text 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_text. 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_text is provided by the Jina AI Remote MCP Server MCP server (jina-ai/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Jina AI Remote MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
