Find strategies that use specific entry or exit signals.
AI agents call search_strategies_by_signal to retrieve information from Mcp Strategy Research Db without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool filters and retrieves strategy records based on signal criteria. It performs a read-only database query against the SQLite backtest results database. There are no side effects, data modifications, code execution, or destructive operations. The sibling tools on this server (compare_*, get_*, find_*) are all query/analysis operations, confirming this is a data retrieval tool.
