preview_plan
AI agents call preview_plan to retrieve information from Keshro MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The name 'preview_plan' strongly implies a read-only action to view or display a plan before committing to it. In the context of sibling tools like 'create_plan', 'generate_plan', and 'export_project', a preview operation typically retrieves and displays data without side effects. However, the empty description lowers confidence significantly.
From the tool's definition Tool name 'preview_plan' suggests a read/view operation; description is empty and uninformative.
