AI agents call get_stock_rt_k to retrieve information from Tushare MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool description is empty, which reduces confidence slightly. However, the consistent pattern across all sibling tools on this Tushare MCP server (which is explicitly described as enabling 'query and search' operations) and the 'get_' naming convention strongly suggest this retrieves stock market data without side effects. No evidence of write, execute, delete, or financial operations.
From the tool's definition Tool name 'get_stock_rt_k' appears to query real-time K-line (candlestick) stock data based on the naming pattern of sibling tools (collect_stock_data, filter_stocks, get_block_trade, get_concept_moneyflow_dc) which are all data retrieval operations.

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