AI agents call get_arcmap_info 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.
The tool merely queries and returns information about the current ArcMap session state without modifying data, executing arbitrary commands, or causing side effects. It falls squarely into the Read category as a data retrieval operation.
From the tool's definition Tool description indicates it retrieves information about the open ArcMap document: 'Info del documento ArcMap abierto: ruta del .mxd, data frames, escala activa' (path of the .mxd file, data frames, active scale).
Attacks that exploit this kind of access
Info del documento ArcMap abierto: ruta del .mxd, data frames, escala activa. 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_arcmap_info: 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_arcmap_info 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_arcmap_info 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_arcmap_info. 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_arcmap_info 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.
