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.
This tool retrieves semantic information from text through embedding-based classification. It produces classifications or predictions as output but does not create, modify, delete, or execute any operations with side effects.
From the tool's definition The tool "classify_text" uses embeddings to categorize text into user-defined labels. The description explicitly states it is used for "categorize, tag, or sort text content" and lists use cases such as "sentiment analysis, topic classification, content…

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 (matifema/jina-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
