AI agents call inst_track_scan 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 appears to perform a scan/query operation on institutional tracking information, consistent with the server's purpose of querying stock data via Tushare API. The empty description reduces confidence, but the naming pattern and sibling tools (all read-like operations: collect, filter, get, analyze) strongly suggest this is a read-only data retrieval tool.

{
"version": "1",
"default": "deny",
"tools": {
"inst_track_scan": {}
}
}inst_track_scan is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
