AI agents call windsurf_get_credit_balance to retrieve information from Sage MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves credit balance information, which is a read-only operation with no side effects. Even though it involves financial data (credit balance), the tool itself only reads/queries this information without moving money or committing financial obligations. The incomplete description ('Get the team') is somewhat unclear, but the tool name strongly indicates a simple balance query.
From the tool's definition Tool name 'windsurf_get_credit_balance' combined with description 'Get the team' indicates a query/retrieval operation. The 'get_' prefix and 'balance' terminology suggest fetching account credit information without modification.
