WHAT IT DOES

What search_school_units_v4 does on Skolverket MCP Server

AI agents call search_school_units_v4 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.

THE RISK

Low Risk

Why search_school_units_v4 needs a policy

This is a purely informational/data retrieval tool. It searches a database of Swedish schools (skolenheter), applies filters (municipality, county, status, type), and returns results. No side effects, no data modification, no code execution, no financial impact. The blast radius of misuse is minimal—an AI agent could retrieve educational data but cannot alter records, delete schools, or trigger external actions.

From the tool's definition Tool description explicitly states it searches ('Sök') and returns ('RETURNERAR: Paginerad lista') school units with filtering and sorting capabilities. Core verbs are search, filter, and retrieve.

POLICY

How to control search_school_units_v4

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 search_school_units_v4:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "search_school_units_v4": {}
  }
}

search_school_units_v4 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 Skolverket 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.
