Lister tous les types de features WFS (données vectorielles)
AI agents call list_wfs_features 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 and enumerates available WFS (Web Feature Service) feature types from geographic data repositories. It performs a read-only query operation without modifying, executing code, or deleting any data. The blast radius of misuse is minimal—an agent could discover available data types but cannot access sensitive data, alter records, or trigger external operations through this tool alone.
From the tool's definition Tool name 'list_wfs_features' and description 'Lister tous les types de features WFS (données vectorielles)' indicate listing/enumeration of WFS feature types.

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

Register the French Open Data & IGN MCP server in PolicyLayer and add a rule for list_wfs_features: 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 French Open Data & IGN. Nothing to install.
list_wfs_features 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 list_wfs_features 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 list_wfs_features. 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.
list_wfs_features 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.
