|---|---|---|---|
| ZYXEL_MOCK | No | If 'true', replays canned output and never contacts a switch. | false |
| ZYXEL_PORT | No | Overrides the protocol default (22 for SSH, 23 for Telnet). | |
| ZYXEL_DEBUG | No | Log every command and response to stderr (true/false). | false |
| ZYXEL_TIMEOUT | No | Command timeout in milliseconds (default: 30000). | 30000 |
| ZYXEL_PROTOCOL | No | Connection protocol: 'ssh' (default) or 'telnet'. | ssh |
| ZYXEL_DEFAULT_HOST | No | Default switch IP address. | |
| ZYXEL_ENABLE_PASSWORD | No | Password for privileged mode (falls back to the login password). | |
| ZYXEL_DEFAULT_PASSWORD | No | Default password for the switch. | |
| ZYXEL_DEFAULT_USERNAME | No | Default username for the switch. |
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 19 tools
Each tool targets a distinct resource or action—show commands for specific data (startup config, running config, interfaces, VLANs, MAC table, spanning tree, ARP), configuration commands for distinct operations, and connection management tools. Even execute_cli serves as an explicit raw fallback rather than causing confusion.
All tools follow the zyxel_verb_noun pattern, consistently using snake_case and clear verbs (show, connect, disconnect, save, configure, create, clear, ping, execute). This makes the tool set predictable and easy to navigate.
With 19 tools, the set is slightly above the typical 3-15 range, but the scope (full switch management) justifies the count. The tools are well-organized and cover essential functionalities without excess.
The surface covers most core switch operations: connection, config display/save, interface configuration, VLAN management, MAC table, spanning tree, ARP, and ping. Minor gaps exist (e.g., no explicit delete_vlan), but the raw execute_cli tool provides a workaround for such operations.
