The tool appears to search or list public filter groups within the QuantData platform. This is a read-only operation with no side effects—it retrieves data for analysis. Even if an AI agent misuses it, the impact is minimal since it only accesses public data. Low severity due to lack of destructive, financial, or code-execution capability.

From the tool's definition Tool name 'qd_search_public_filter_groups' indicates a search operation on public filter groups, which is a read-only retrieval action. No description provided, but the 'search' verb and 'public' scope suggest querying existing data without modification.

POLICY

How to control qd_search_public_filter_groups

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

policy.json

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

qd_search_public_filter_groups is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register QuantData MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
