Lists all SNS topics.
AI agents call list_sns_topics to retrieve information from AWS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates SNS topics—a data discovery operation with no capability to create, modify, delete, or execute actions. The read-only nature of the server and the passive listing operation confirm the Read category.
From the tool's definition Tool name 'list_sns_topics' and description 'Lists all SNS topics' indicate a query/list operation that retrieves information without modification. The server is explicitly described as 'read-only' and this tool performs no side effects.
