What generate_wallet does on Monad MCP Server

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

WHY IT NEEDS A POLICY

Why generate_wallet needs a policy

This tool creates new cryptographic credentials that enable write operations (transactions, token transfers). Although generation itself is benign, the output (private key) grants the holder power to execute Write and Financial actions on the blockchain. Classified as Write rather than Execute because the tool itself only generates credentials; it doesn't execute transactions.

From the tool's definition Tool generates a new Ethereum wallet, producing persistently stored cryptographic credentials (address, private key, seed phrase). While the act of generation itself is not destructive, it creates new write-capable state in a blockchain context.
