Why delete_kafka_connector needs a policy

Deleting a Kafka connector terminates data pipelines and cannot be undone without manual recreation. This is irreversible infrastructure modification with potential operational impact (data flow interruption). While not data deletion per se, it destroys connector state/configuration.

From the tool's definition Tool name explicitly contains 'delete' and description states 'Deletes a Kafka connector.' Deletion of connectors is irreversible—once removed, the connector configuration and its operational state are lost.

POLICY

How to control delete_kafka_connector

PolicyLayer is an MCP gateway — it sits between your AI agents and Lenses MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_kafka_connector:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_kafka_connector"
  ]
}

delete_kafka_connector disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Lenses MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
