replicate_record · Devon MCP: Risk & Policy

WHAT IT DOES

What replicate_record does on Devon

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

WHY IT NEEDS A POLICY

Why replicate_record needs a policy

Replicating a record creates a new reference/copy of the record in another group. This is a reversible write operation — the replica can be removed later. It does not delete or overwrite data, execute code, or involve financial operations. The blast radius is medium since an AI agent could create many spurious replicas cluttering the database, but no data is permanently lost.

replicate_record Rate-limited

replicate_record 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.
