The 'get' verb and 'details' retrieval pattern confirm a Read operation. Severity is low as exposure of these metadata details poses minimal security risk compared to write or destructive operations on Fabric ontology items.

From the tool's definition Tool name 'get_kql_database_details' and description 'Get details of a KQL database including its query URI, database name, and parent Eventhouse' indicate retrieval of metadata without modification or deletion.

How to control get_kql_database_details

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

policy.json

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

get_kql_database_details 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 Fabric Ontology 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.
