List all diseases that have been scraped and are available in the database.
AI agents call list_available_diseases to retrieve information from Meducate MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a simple database query to retrieve a list of diseases. It does not create, modify, delete, or execute any operations. It does not involve financial transactions or external command execution. The operation is read-only and carries minimal risk even if invoked by an AI agent, as it only exposes informational data already intended for retrieval.
From the tool's definition Tool description states 'List all diseases that have been scraped and are available in the database' - this is a retrieval/query operation with no side effects.
