AI agents call get_subject_versions to retrieve information from Skolverket MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward data retrieval tool that queries historical curriculum versions from Skolverket's open APIs. It has no side effects, cannot modify or delete data, and poses minimal risk even if misused by an AI agent. The worst-case scenario would be information disclosure of already-public educational data.
From the tool's definition Tool description states it 'Hämta alla tillgängliga versioner av ett ämne' (retrieves all available versions of a subject) and returns 'Lista över alla versioner' (list of all versions).
Documented attack patterns abuse exactly the kind of access get_subject_versions gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Skolverket MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_subject_versions:
{
"version": "1",
"default": "deny",
"tools": {
"get_subject_versions": {}
}
}get_subject_versions is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

ANVÄNDNINGSFALL: - Följa hur ett ämne förändrats över tid - Jämföra nuvarande läroplan med tidigare versioner - Forskning om läroplansförändringar - Förstå progressionen i ämnets utveckling RETURNERAR: Lista över alla versioner med versionsnummer och giltighetsdatum. TIPS: Använd sedan get_subject_details med specifikt versionsnummer för att jämföra. It is categorised as a Read tool in the Skolverket MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Skolverket MCP Server MCP server in PolicyLayer and add a rule for get_subject_versions: 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 Skolverket MCP Server. Nothing to install.
get_subject_versions 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 get_subject_versions 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 get_subject_versions. 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.
get_subject_versions is provided by the Skolverket MCP Server MCP server (isakskogstad/skolverket-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Skolverket MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
