normalize_index_code

What normalize_index_code does on A-Share MCP Server

AI agents call normalize_index_code to retrieve information from A-Share MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why normalize_index_code is rated Low

This is a utility function that converts or maps index code formats without retrieving, modifying, deleting, or executing operations. It performs a stateless transformation on input parameters. The blast radius of misuse is negligible—incorrect normalization might cause failed lookups or return no results, but cannot corrupt data, execute code, or trigger financial transactions.

From the tool's definition Tool normalizes index codes to a standard format; the description indicates data transformation/lookup with no modification of underlying data ('Normalize common index codes to Baostock format').

The rule that runs normalize_index_code safely

PolicyLayer is an MCP gateway: it sits between your AI agents and A-Share MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For normalize_index_code, this is the rule to start with:

{
  "version": "1",
  "default": "deny",
  "tools": {
    "normalize_index_code": {}
  }
}
