Generic query interface for Geoportail WFS layers. This tool provides access to various WFS layers from the IGN Geoportail. It allows querying any WFS layer by intersection with a geometry. Args: - source (string): WFS data source name (e.g.,
AI agents call ign_wfs_geoportail to retrieve information from IGN API Carto 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 data retrieval tool that queries French geographic information system (WFS—Web Feature Service) layers. It permits read-only access to cadastral, agricultural, administrative, and environmental data. While the data retrieved may be sensitive (property boundaries, agricultural classifications), the tool itself performs no destructive, executable, or financial operations.
From the tool's definition Tool description states it 'allows querying any WFS layer by intersection with a geometry' and is described as a 'Generic query interface'. The args include 'source (string): WFS data source name', indicating it retrieves geographic data without modification.

Generic query interface for Geoportail WFS layers. This tool provides access to various WFS layers from the IGN Geoportail. It allows querying any WFS layer by intersection with a geometry. Args: - source (string): WFS data source name (e.g.,. It is categorised as a Read tool in the IGN API Carto MCP Server MCP Server, which means it retrieves data without modifying state.
Register the IGN API Carto MCP Server MCP server in PolicyLayer and add a rule for ign_wfs_geoportail: 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 IGN API Carto MCP Server. Nothing to install.
ign_wfs_geoportail 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 ign_wfs_geoportail 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 ign_wfs_geoportail. 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.
ign_wfs_geoportail is provided by the IGN API Carto MCP Server MCP server (julienkalamon/ign-apicarto-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
