Why inspect_local_concept needs a policy

This tool performs semantic analysis and retrieval of ontology metadata (classes, concepts, profiles) from the Italian government data catalog. While it accesses potentially sensitive government data structures, the core operation is read-only with no side effects on the underlying data.

From the tool's definition Tool retrieves and returns "a full profile of a class or concept from a local or uploaded ontology" — this is a read/query operation that semantically explores and analyzes data structures without modifying them. The description indicates data retrieval only.

POLICY

How to control inspect_local_concept

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

policy.json

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

inspect_local_concept 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 Schema Gov It 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.
