AI agents call get_vast_zone_tags to retrieve information from AdButler without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

id | number | Yes | VAST zone ID |
Parameters from the server's own tool schema.
This tool retrieves VAST (Video Ad Serving Template) zone tags, which are configuration identifiers used for ad serving. Retrieving tags is a non-destructive read operation that queries existing data without modification, deletion, or execution of external code. The blast radius of misuse is minimal—an attacker gains only read access to ad zone configuration metadata.
From the tool's definition Tool name 'get_vast_zone_tags' and description 'Get VAST zone serving tags' indicate a retrieval operation. The verb 'get' combined with 'serving tags' (metadata/configuration information) shows this is a read-only query with no side effects.
