server_services_directory_list
AI agents call server_services_directory_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.
The tool appears to retrieve or query a directory of services on an ArcGIS server. While the description is uninformative, the naming strongly suggests a read operation that retrieves metadata or status about services without modifying state. Compared to sibling tools like 'admin_services_health' (also read) and 'admin_servers_list' (also read), this fits the Read category.
From the tool's definition Tool name 'server_services_directory_list' indicates listing/retrieving directory information about services. The 'list' verb and 'directory' naming pattern align with read-only query operations. Empty description limits confidence slightly.

server_services_directory_list. 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_services_directory_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_services_directory_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_services_directory_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_services_directory_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_services_directory_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.
