Get transactions to and from the wallet address
AI agents call getTransactionsForAddress 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.

It has no side effects: it does not execute code, modify blockchain state, delete data, or commit financial transactions. The blast radius of misuse is low, as an agent querying transaction history cannot harm systems or data. The informative description confirms read-only intent.
