AI agents call list_feature_classes to retrieve information from Arcmap 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 information about available feature classes within a workspace. It has no side effects, creates no data, executes no external operations, and modifies nothing. It is purely informational/exploratory in nature, making it a straightforward Read category tool.
From the tool's definition Tool name 'list_feature_classes' and description 'Lista las feature classes de un workspace' indicates it lists/enumerates feature classes without modifying them.
Attacks that exploit this kind of access
Lista las feature classes de un workspace (incluye las dentro de datasets). Si no. It is categorised as a Read tool in the Arcmap MCP Server, which means it retrieves data without modifying state.
Register the Arcmap MCP server in PolicyLayer and add a rule for list_feature_classes: 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 Arcmap. Nothing to install.
list_feature_classes 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_feature_classes 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_feature_classes. 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_feature_classes is provided by the Arcmap MCP server (pedralcg/arcmap-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
