Get the total SOL supply and circulation info
AI agents call get_supply to retrieve information from Solana MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns information about SOL supply metrics. It performs no state changes, executes no code, and has no destructive, financial, or reversible write effects. It is a simple data query operation with minimal blast radius if misused by an agent—worst case being incorrect information returned to the user.
