AI agents call boe_departaments to retrieve information from Mcp Govern without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a straightforward data retrieval—listing available departments from the BOE (Boletín Oficial del Estado, Spain's Official State Gazette). There is no creation, modification, deletion, code execution, or financial transaction involved. The blast radius of misuse is minimal, as listing public departments causes no harm.
From the tool's definition Tool name 'boe_departaments' and description 'Llista tots els departaments disponibles al BOE' (Lists all departments available in the BOE) indicate a retrieval operation that queries and returns a list of public government departments with no side effects.

{
"version": "1",
"default": "deny",
"tools": {
"boe_departaments": {}
}
}boe_departaments is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
