relate · Oceanir Memory MCP: Risk & Policy

WHAT IT DOES

What relate does on Oceanir Memory

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

WHY IT NEEDS A POLICY

Why relate needs a policy

This tool modifies the knowledge graph by creating new relationships between entities, which is a Write operation (reversible data modification). It's not Read because it changes state, not Execute/Destructive because it doesn't run arbitrary code or delete data, and not Financial.

From the tool's definition The tool 'relate' creates a relationship between two memory entities, which is a modification operation that adds new data to the persistent memory system.

relate Rate-limited

relate 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.
