WHAT IT DOES

What refresh_data does on MCP Rust/Slint Development Server

AI agents invoke refresh_data to trigger actions in MCP Rust/Slint Development Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why refresh_data needs a policy

Based on the server context, this tool likely triggers a refresh/re-fetch of cached data from GitHub repositories. That constitutes an external operation (fetching and re-caching data), placing it in the Execute category. However, since the description is empty, confidence is lowered. It could also be Write if it merely updates a local cache.

From the tool's definition Tool name 'refresh_data'; description is empty and uninformative.
