Get a specific advanced spending ruleset by ID
AI agents call pex_get_advanced_spending_ruleset to retrieve information from PEX 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 spending ruleset configuration data by ID without side effects. It is a read-only query operation that does not create, modify, delete, or execute any financial transactions. While it accesses business spending policy information, the retrieval itself poses minimal risk; misuse would only expose data already accessible to authorized account holders.
