Retrieve all accounts for a specific budget.
AI agents call get_accounts to retrieve information from YNAB 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 account information from a budget without creating, modifying, deleting, or executing any operations. It is a straightforward data retrieval operation, making it a Read category risk with low severity, as the worst case is exposure of account metadata without financial harm from the tool's execution itself.
