List all topics in the Kafka cluster
AI agents call kafka_list_topics 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 queries and returns information about existing Kafka topics without modifying, creating, deleting, or executing any operations. It is a pure read operation with minimal security impact if misused by an AI agent—the worst outcome is information disclosure about cluster topology.
From the tool's definition Tool name is 'kafka_list_topics' and description states 'List all topics in the Kafka cluster' — a retrieval operation with no side effects.
Attacks that exploit this kind of access
List all topics in the Kafka cluster. 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 kafka_list_topics: 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.
kafka_list_topics 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 kafka_list_topics 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 kafka_list_topics. 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.
kafka_list_topics is provided by the Kafka MCP Server MCP server (joel-hanson/kafka-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
