Obtiene información detallada de un usuario por su nombre de usuario.
AI agents call user_get 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 queries and returns user information based on a username parameter. It performs a simple lookup operation without modifying, deleting, or executing any code. The operation is read-only and poses minimal risk even if misused—at worst, an agent could enumerate user details in an ArcGIS system.
From the tool's definition Tool name 'user_get' and description 'Obtiene información detallada de un usuario por su nombre de usuario' (retrieves detailed information about a user by username) indicate a data retrieval operation with no side effects.
Attacks that exploit this kind of access
Obtiene información detallada de un usuario por su nombre de usuario. 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 user_get: 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.
user_get 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 user_get 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 user_get. 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.
user_get 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.
