export_ddp · Arcmap MCP: Risk & Policy

WHAT IT DOES

What export_ddp does on Arcmap

AI agents use export_ddp to create or update resources in Arcmap — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Arcmap environment.

WHY IT NEEDS A POLICY

Why export_ddp needs a policy

Export operations create or write file outputs to disk. While exports are generally reversible (files can be deleted), the act of exporting can overwrite existing files and produces persistent side effects. This is classified as Write rather than Read because it generates and persists data artifacts.

From the tool's definition Tool named 'export_ddp' with empty description on an ArcMap control server; sibling tools include export_jpg and export_pdf which suggest data export functionality. DDP likely refers to a proprietary or specialized ArcMap document/data format.

Verdict

export_ddp Rate-limited

export_ddp stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about export_ddp

What does the export_ddp tool do? +

export_ddp. It is categorised as a Write tool in the Arcmap MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on export_ddp? +

Register the Arcmap MCP server in PolicyLayer and add a rule for export_ddp: 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.

What risk level is export_ddp? +

export_ddp is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit export_ddp? +

Yes. Add a rate_limit block to the export_ddp 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.

How do I block export_ddp completely? +

Set action: deny in the PolicyLayer policy for export_ddp. 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.

What MCP server provides export_ddp? +

export_ddp 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.
