AI agents call get_workspace 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 returns current workspace configuration from the ArcMap environment. It performs no data modification, deletion, code execution, or external operations—it simply queries and returns existing environment variables. The blast radius of misuse is minimal: an agent could only learn the current workspace paths, which are already known to the system. This is a straightforward read operation.
From the tool's definition Tool name 'get_workspace' and description 'Returns the current workspace and scratch workspace of arcpy.env' indicate a query operation that retrieves environment configuration without modifying state.
Attacks that exploit this kind of access
Devuelve el workspace y scratch workspace actuales de arcpy.env. 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 get_workspace: 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.
get_workspace 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 get_workspace 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 get_workspace. 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.
get_workspace 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.
get_workspace is one line of Arcmap's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
