WHAT IT DOES

What set_memory_owner does on Mapi Agent Memory

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

RISK

Why set_memory_owner is rated Medium

The tool modifies a memory record's owner field, which is reversible and does not directly delete data or execute arbitrary operations. This is a write operation on governance metadata. Severity is medium because changing ownership could affect access controls and audit trails in an agent memory system, but the operation itself is not destructive or financially consequential.

From the tool's definition Tool name 'set_memory_owner' indicates assignment or modification of ownership metadata. No description provided, but context of sibling tools like 'apply_memory_lifecycle_remediation' and 'apply_conflict_resolution' suggests memory state modification.

RECOMMENDED RULE

The rule that runs set_memory_owner safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mapi Agent Memory, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For set_memory_owner, this is the rule to start with:

set_memory_owner Rate-limited

set_memory_owner 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Mapi Agent Memory, apply this rule, and every set_memory_owner call is checked against it from then on.
