cluster_info
AI agents call cluster_info 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.
cluster_info appears to retrieve cluster metadata information from Kafka brokers without modifying or deleting any data. This is consistent with read-only operations like health checks and metadata inspection. No arguments are mentioned that would enable destructive or financial actions. The tool fits the Read category as it queries cluster state.
From the tool's definition Tool name 'cluster_info' combined with server context describing 'broker metadata inspection' and the sibling tools which include query/list operations (list_topics, list_consumer_groups, list_kafka_users, health).
Attacks that exploit this kind of access
cluster_info. 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 cluster_info: 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.
cluster_info 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 cluster_info 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 cluster_info. 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.
cluster_info is provided by the Kafka MCP Server MCP server (jilanisayyad/kafka-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
