AI agents call get_commune_info to retrieve information from French Open Data & IGN without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about French communes (municipalities) from public data sources. It performs a read-only query with no side effects, mutations, or external actions. The truncated description prevents full certainty, but the naming convention and context within a data access server confirm it as a retrieval operation.
From the tool's definition Tool name 'get_commune_info' and verb 'Obtenir' (French: to get/retrieve) indicate data retrieval. Description is truncated ('Obtenir toutes les informations d') but the pattern matches sibling read-only tools (get_dataset, get_organization, get_region_info)…

PolicyLayer is an MCP gateway — it sits between your AI agents and French Open Data & IGN, and nothing reaches the server without passing your rules. This is the rule we recommend for get_commune_info:
{
"version": "1",
"default": "deny",
"tools": {
"get_commune_info": {}
}
}get_commune_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Yes. Add a rate_limit block to the get_commune_info 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.

get_commune_info is provided by the French Open Data & IGN MCP server (nikoko107/mcp-datagouv-ign). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
