get_feishu_prompt
AI agents call get_feishu_prompt to retrieve information from RT-Prompt-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves prompt suggestions, likely for the Feishu platform integration. It matches the server's primary function of providing prompt recommendations without modifying data or executing code. The 'get_' prefix and consistency with sibling tools strongly indicates a read operation.
From the tool's definition Tool name 'get_feishu_prompt' contains 'get', a retrieval verb. Server context describes providing 'prompt suggestions' which are read-only recommendations. Sister tools (get_backend_suggestions, get_frontend_suggestions, etc.) are all retrieval operations.
