ref_finance_get_pools
AI agents call ref_finance_get_pools to retrieve information from NEAR MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to fetch or list pools from a DeFi protocol, which is a read-only query with no side effects. Despite the empty description reducing confidence slightly, the naming convention and context (sibling tools show account operations, access key management) indicate this retrieves data without modifying state or executing arbitrary code. No financial transactions, deletions, or code execution are implied.
