What refresh_databases does on Phalcon MCP Server

AI agents call refresh_databases to retrieve information from Phalcon MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why refresh_databases needs a policy

The tool appears to refresh/reload a cached list of database paths, which is a read operation that queries available databases. No data is created, modified, or deleted. Confidence is moderate because the description is brief and 'refresh' could imply some side effects, but in context it likely just re-reads and updates an in-memory list.
