THE RISK

Low Risk

Why get_generic_attributes needs a policy

This tool queries and retrieves generic attributes from the 3DCityDB database without creating, modifying, deleting, or executing code. It is a straightforward data retrieval operation with no side effects or external operations triggered. The low severity reflects minimal blast radius—misuse would only expose existing database information, not corrupt or destroy data.

From the tool's definition Tool name 'get_generic_attributes' and description 'Fetches generic attributes' indicate a retrieval operation with no modification or deletion capability. The verb 'Fetches' confirms read-only semantics.

POLICY

How to control get_generic_attributes

PolicyLayer is an MCP gateway — it sits between your AI agents and 3DCityDB MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_generic_attributes:

policy.json

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

get_generic_attributes 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 3DCityDB 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.
