Get users/authors from your Canny instance
AI agents call get_users to retrieve information from Canny 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 user/author information from Canny without creating, modifying, or deleting data. It has no side effects and poses minimal security risk. Exposure of user lists in a feedback management system is a standard read operation with low blast radius if misused by an agent.
From the tool's definition Tool name 'get_users' and description 'Get users/authors from your Canny instance' indicate data retrieval with no modification. The verb 'Get' and lack of any write/delete/execute operations confirm read-only access.
