Get all tags in Bear
AI agents call get_tags to retrieve information from Bear MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves tag metadata from Bear without side effects. It falls clearly into the Read category as it only fetches information. Severity is low because unauthorized tag enumeration poses minimal risk—tags are metadata typically visible to the user and do not expose sensitive note contents. The confidence is high given the explicit 'Get' verb and lack of modification language in the description.
From the tool's definition Tool name 'get_tags' and description 'Get all tags in Bear' indicate a read-only retrieval operation that lists existing tags without modifying or deleting data.
