WHAT IT DOES

What activitywatch_list_buckets does on ActivityWatch MCP Server

AI agents call activitywatch_list_buckets to retrieve information from ActivityWatch MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why activitywatch_list_buckets is rated Low

The tool performs a straightforward query of ActivityWatch buckets without creating, modifying, deleting, or executing operations. It only retrieves metadata about available data sources/buckets. Even if an AI agent calls this tool, it cannot cause harm beyond potentially exposing non-sensitive structural information about what data is tracked (e.g., 'computer' bucket, 'web' bucket).

From the tool's definition Tool name is 'list_buckets' and description states 'List all ActivityWatch buckets with optional type filtering' — this is a retrieval operation with no modification or side effects.
