Gets token details for a specific token of an NFT contract.
AI agents call getNFTtokensByIdForAddress to retrieve information from Somnia 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 NFT token metadata without creating, modifying, deleting, or executing any operations. It is a straightforward data query against blockchain state, analogous to fetching read-only information about token ownership or attributes. Low severity because misuse results only in information disclosure, not financial loss or destructive actions.
