Lista las máquinas registradas en el ArcGIS Server site.
AI agents call server_machines_list 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 performs a read-only operation—listing/enumerating registered machines on an ArcGIS Server site. It retrieves data with no side effects, no code execution, and no destructive or financial actions. While the information returned could be sensitive (infrastructure inventory), the tool itself is fundamentally a retrieval operation.
From the tool's definition Tool name 'server_machines_list' and description 'Lista las máquinas registradas en el ArcGIS Server site' (Lists the machines registered in the ArcGIS Server site) indicate a query/list operation that retrieves information about registered server machines…
Attacks that exploit this kind of access
Lista las máquinas registradas en el ArcGIS Server site. 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 server_machines_list: 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.
server_machines_list 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 server_machines_list 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 server_machines_list. 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.
server_machines_list 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.
