AI agents call analyze_stock to retrieve information from Wyckoff Trading Agent MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
analyze_stock retrieves and analyzes stock data for diagnostic purposes. The 'diagnose' mode interprets technical analysis patterns, and the 'price' mode returns historical price information. Neither mode creates, modifies, deletes, or executes external operations—they are pure read operations on market data.
From the tool's definition The tool description states it performs 'Wyckoff 结构诊断' (Wyckoff structure diagnosis) and returns 'OHLCV 数据' (price data).

PolicyLayer is an MCP gateway — it sits between your AI agents and Wyckoff Trading Agent MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for analyze_stock:
{
"version": "1",
"default": "deny",
"tools": {
"analyze_stock": {}
}
}analyze_stock is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
