WHAT IT DOES

What mint_batch_nfts does on SEI MCP Server V2

AI agents use mint_batch_nfts to create or update resources in SEI MCP Server V2 — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your SEI MCP Server V2 environment.

WHY IT NEEDS A POLICY

Why mint_batch_nfts needs a policy

Minting creates new on-chain assets (NFTs) on a smart contract, which is a write/create operation. While it produces new tokens, it does not delete or overwrite existing data, placing it in the Write category. Severity is high because batch minting can consume significant gas, alter contract state at scale, and if misused could flood a collection or drain funds associated with minting costs.

From the tool's definition Mints a batch of new NFTs to a specified wallet address on an ERC721 contract
