Lista todas las capas y tablas de un item de servicio.
AI agents call item_layers to retrieve information from ArcGIS MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists metadata about layers and tables within a service item. It is a read-only query operation that returns information about existing resources without creating, modifying, deleting, or executing any side effects. The blast radius is minimal as it only exposes structural information about a service.
From the tool's definition Tool description states 'Lista todas las capas y tablas de un item de servicio' (Lists all layers and tables of a service item). The verb 'lista' (list) indicates retrieval/enumeration with no modification of data.
Attacks that exploit this kind of access
Lista todas las capas y tablas de un item de servicio. It is categorised as a Read tool in the ArcGIS MCP MCP Server, which means it retrieves data without modifying state.
Register the ArcGIS MCP server in PolicyLayer and add a rule for item_layers: 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 ArcGIS MCP. Nothing to install.
item_layers 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 item_layers 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 item_layers. 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.
item_layers is provided by the ArcGIS MCP server (renemorenow/arcgis-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
