WHAT IT DOES

What memory_create_relations does on VaultAssist

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

RISK

Why memory_create_relations is rated Medium

The tool creates and stores new relationships, which is a reversible write operation. It doesn't retrieve data (Read), execute external commands (Execute), irreversibly delete data (Destructive), or involve financial transactions (Financial). The medium severity reflects that bulk relationship creation could impact user data organization and privacy, but relationships can typically be modified or deleted afterward.

From the tool's definition Tool name includes 'create' and description states 'Create and store multiple new relationships between entities'; this is a data creation operation that modifies user state.

RECOMMENDED RULE

The rule that runs memory_create_relations safely

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

memory_create_relations Rate-limited

memory_create_relations 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.
