Browse pre-built sets of market drivers (e.g. interest rates, volatility, commodities). Returns template names, factors, and conditioning_set_id needed by analyze_quantitative.
AI agents call list_feature_set_templates to retrieve information from Sablier 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 metadata about pre-built market driver templates. It performs a read-only operation that returns reference data (names, factors, IDs) needed for downstream analysis, with no side effects, data modification, or code execution. The naming verb 'list' and action 'Browse' confirm it is purely informational.
From the tool's definition Tool description states 'Browse pre-built sets' and 'Returns template names, factors, and conditioning_set_id' — indicating a retrieval/query operation with no data modification or execution.
