This tool retrieves and queries financial market data about mutual funds without creating, modifying, deleting, or executing any operations. It is a read-only data retrieval endpoint.

From the tool's definition API returns data about mutual funds including summary, performance, risk, ratings, composition, purchase_info, and sustainability. The description uses passive language ('returns') and lists informational fields only.

PolicyLayer is an MCP gateway — it sits between your AI agents and Twelve Data MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for GetMutualFundsWorld:

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