List all Kafka consumer groups.
AI agents call get_consumer_groups 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 metadata about consumer groups from the Kafka cluster. It performs a read-only operation that queries existing state without creating, modifying, deleting, or executing operations. The blast radius of misuse is limited to information disclosure about consumer group configuration and status.
From the tool's definition Tool name 'get_consumer_groups' and description 'List all Kafka consumer groups' indicate a query/retrieval operation with no data modification or side effects.
Attacks that exploit this kind of access
List all Kafka consumer groups. 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 get_consumer_groups: 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.
get_consumer_groups 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 get_consumer_groups 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 get_consumer_groups. 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.
get_consumer_groups 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.
