What create_token does on Solana MCP Server

AI agents use create_token to create or update resources in Solana MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Solana MCP Server environment.

WHY IT NEEDS A POLICY

Token creation is a write operation that modifies the blockchain state by introducing a new asset. While the operation itself is technically irreversible once executed, it does not destroy or overwrite existing data (which would be Destructive), nor does it move funds (Financial), nor does it execute arbitrary code (Execute).
