List all webhooks for a base
AI agents call list_webhooks to retrieve information from Airtable MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and returns existing webhook configurations without creating, modifying, or deleting any data. It is a read-only operation that has no impact on the system state. Severity is low because webhook metadata exposure has minimal blast radius—it reveals configuration but does not enable unauthorized actions without separate Write/Execute permissions.
From the tool's definition Tool name 'list_webhooks' and description 'List all webhooks for a base' indicate a retrieval operation with no side effects.
