repair_data_source · Arcmap MCP: Risk & Policy

WHAT IT DOES

What repair_data_source does on Arcmap

AI agents use repair_data_source 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 repair_data_source needs a policy

This tool modifies the data source/workspace reference of a layer, which is a reversible write operation (the old path can be restored). However, it has high severity because remapping data sources in a live ArcMap session could break layer connections or redirect analysis to incorrect datasets, potentially causing significant downstream errors. Confidence is slightly reduced because the description is truncated.

From the tool's definition 'Reapunta la fuente de una capa sustituyendo su workspace' (re-points the source of a layer by substituting its workspace)

repair_data_source Rate-limited

repair_data_source 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.
