Metadata Tools in MCP‑Kafka Servers

MCP‑Kafka servers typically expose a suite of metadata‑oriented “tools” that LLMs can invoke to inspect and manage Kafka clusters. Commonly supported operations include:

• list_brokers: Returns broker IDs, hostnames, and port configurations.

• list_topics: Retrieves all topic names along with partition counts and replication factors.

• describe_topic: Provides per‑partition leader and replica assignments, ISR (in‑sync replicas), and retention settings.

• list_consumer_groups: Enumerates active consumer groups and their member assignments.

• describe_consumer_group: Shows each group’s partition offsets, lag metrics, and rebalance state.

• describe_configs: Fetches topic‑ or broker‑level configuration entries (e.g., min.insync.replicas, unclean.leader.election.enable).

• cluster_overview: Aggregates high‑level cluster health data, such as under‑replicated partitions, offline partitions, and controller status.
