WHAT IT DOES

What list_kafka_topics does on Vultr MCP

AI agents call list_kafka_topics to retrieve information from Vultr MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_kafka_topics is rated Low

This tool queries and retrieves information about Kafka topics without creating, modifying, deleting, or executing any operations. It is a read-only data retrieval action with minimal blast radius if misused—at worst, an AI agent gains visibility into existing Kafka topic configuration.

From the tool's definition Tool name 'list_kafka_topics' and description 'List Kafka topics' indicate a retrieval/query operation with no modification or side effects.

RECOMMENDED RULE

The rule that runs list_kafka_topics safely

list_kafka_topics Allowed

list_kafka_topics is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
