WHAT IT DOES

What ruvector_update does on Claude Flow

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

RISK

Why ruvector_update is rated Medium

The tool updates vector data and metadata, which is a write operation that creates or modifies data in a reversible manner. In the context of a hive-mind AI orchestration system, vectors likely represent learned embeddings or agent states.

From the tool's definition Tool description states 'Update an existing vector and/or its metadata' — this modifies data reversibly without deletion or irreversible consequences.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs ruvector_update safely

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

ruvector_update Rate-limited

ruvector_update 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.
