Describe details of a Kafka topic.
AI agents call describe_topic to retrieve information from Kafka 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 returns information about a Kafka topic (such as partitions, replication factor, configuration, etc.). It has no side effects, does not modify data, does not execute code or commands, and does not delete or move resources. It is purely informational, matching the 'Read' category definition of querying data with no side effects.
From the tool's definition The tool is named 'describe_topic' and described as 'Describe details of a Kafka topic.' The verb 'describe' and the action of retrieving topic details indicate a read-only operation that queries metadata without modifying or executing operations.
Attacks that exploit this kind of access
Describe details of a Kafka topic. It is categorised as a Read tool in the Kafka MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Kafka MCP Server MCP server in PolicyLayer and add a rule for describe_topic: 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 Kafka MCP Server. Nothing to install.
describe_topic 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 describe_topic 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 describe_topic. 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.
describe_topic is provided by the Kafka MCP Server MCP server (shivamxtech/kafka-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
