AI agents call list_gis_layers to retrieve information from ArcGIS Pro Bridge MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries existing GIS project metadata (maps, layers, fields, spatial references) without creating, modifying, deleting, or executing operations. It is purely informational and returns Resource URIs for reference. No destructive, financial, or execution-based actions occur.
From the tool's definition Tool name 'list_gis_layers' and description 'lists maps, layers, fields and spatial references in a project and returns corresponding Resource URI' indicate data retrieval with no modification or side effects.
Documented attack patterns abuse exactly the kind of access list_gis_layers gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and ArcGIS Pro Bridge MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_gis_layers:
{
"version": "1",
"default": "deny",
"tools": {
"list_gis_layers": {}
}
}list_gis_layers is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the ArcGIS Pro Bridge MCP Server MCP server in PolicyLayer and add a rule for list_gis_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 Pro Bridge MCP Server. Nothing to install.
list_gis_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 list_gis_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 list_gis_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.
list_gis_layers is provided by the ArcGIS Pro Bridge MCP Server MCP server (sangwxx/arcgis-pro-bridge-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
