Get assets by update authority address
AI agents call getAssetsByAuthority to retrieve information from AMOCA Solana MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query operation on the Solana blockchain to fetch asset metadata filtered by authority. It has no side effects, does not modify state, execute code with variable behavior, delete data, or move funds. The severity is low because misuse (e.g., querying unauthorized assets) would only expose information already available on-chain, not cause financial loss or irreversible harm.
From the tool's definition Tool is named 'getAssetsByAuthority' with description 'Get assets by update authority address' — this retrieves or queries data about assets based on an authority parameter without modifying, deleting, or executing transactions.
