AI agents call recommend_external_endpoints to retrieve information from Schema Gov It MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool exclusively retrieves and presents pre-curated endpoint data from the schema.gov.it catalog. It has no side effects, does not modify data, execute queries, or trigger external operations. The filtering parameter is a simple selection mechanism over static data. The 'public' qualifier confirms these are read-only reference endpoints, not administrative or potentially destructive interfaces.
From the tool's definition The tool returns a 'curated list' of public SPARQL endpoints with optional category filtering. The description uses passive voice ('Return') and provides information retrieval only. No write, delete, or execution capabilities are described.
Documented attack patterns abuse exactly the kind of access recommend_external_endpoints gives an agent:
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 recommend_external_endpoints:
{
"version": "1",
"default": "deny",
"tools": {
"recommend_external_endpoints": {}
}
}recommend_external_endpoints is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Return a curated list of useful public SPARQL endpoints to pair with schema.gov.it. Args: - category: (optional) Filter by endpoint family:. It is categorised as a Read tool in the Schema Gov It MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Schema Gov It MCP Server MCP server in PolicyLayer and add a rule for recommend_external_endpoints: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Schema Gov It MCP Server. Nothing to install.
recommend_external_endpoints is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the recommend_external_endpoints rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for recommend_external_endpoints. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
recommend_external_endpoints is provided by the Schema Gov It MCP Server MCP server (italia/dati-semantic-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Schema Gov It MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
