List NFT collections. Optionally filter by creator address.
AI agents call list_nft_collections to retrieve information from Tenzro Ledger MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries NFT collection metadata without side effects. It performs a read-only operation that may filter results but does not create, modify, delete, or execute any state-changing actions. The optional filtering parameter does not escalate the risk category. Misuse by an AI agent would be limited to information disclosure, which poses minimal risk.
From the tool's definition Tool name 'list_nft_collections' and description 'List NFT collections' indicate a query/retrieval operation with optional filtering by creator address. No data modification, deletion, or financial transaction occurs.
