Server Configuration
Describes the environment variables required to run the server.
| Name | Required | Description | Default |
|---|---|---|---|
| CONNECT_URL | Yes | Base URL of the Kafka Connect REST API. | |
| DEBEZIUM_MODE | No | Access mode. read-only exposes monitoring only; read-write adds lifecycle management; admin adds delete. Tools above the mode are never registered. | read-only |
| DEBEZIUM_DRY_RUN | No | When true, write/admin tools validate and log intent without calling Kafka Connect. | false |
| DEBEZIUM_AUDIT_LOG | No | When true, emits a JSON line to stderr per guarded operation. | true |
| DEBEZIUM_ALLOW_DELETE | No | Enables the delete_connector tool when combined with admin mode. | false |
| DEBEZIUM_CONNECTOR_ALLOWLIST | No | Comma-separated list of connectors that are in scope. When set, operations on other connectors are refused. Defaults to all connectors. | |
| DEBEZIUM_PROTECTED_CONNECTORS | No | Comma-separated list of connectors that are read-only forever. Inspectable but never paused, reconfigured, or deleted. Defaults to none. |
Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.

Scored across 7 tools
Most tools target distinct aspects of Kafka Connect/Debezium introspection. get_connector overlaps somewhat with get_connector_config and get_connector_status because it returns full connector info including config and tasks, but the descriptions clarify the specialized scopes.
The naming is mostly consistent snake_case with clear verb_noun patterns such as get_connector_config and list_connectors. cluster_info is a minor deviation because it lacks a verb, but it remains readable and predictable.
Seven tools is well-scoped for a connector introspection server. Each tool covers a distinct read-only concern, from connector lists and configs to status, topics, plugins, and cluster info.
The read-only introspection surface is largely complete: connectors, config, status, topics, plugins, and cluster details are covered. Mutation or lifecycle operations like create, update, restart, pause, and delete are absent, but they may be outside this server's apparent monitoring scope.
