ruvector_insert · Claude Flow MCP: Risk & Policy

WHAT IT DOES

What ruvector_insert does on Claude Flow

AI agents use ruvector_insert 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.

WHY IT NEEDS A POLICY

Why ruvector_insert needs a policy

This tool creates or modifies vector data in a table through insertion and upsert operations. These are reversible write operations (data can be updated or deleted later). The batch capability increases blast radius slightly—an agent could insert large volumes of data—but insertion itself is not destructive.

From the tool's definition Tool name 'ruvector_insert' combined with description 'Insert vectors into a table. Supports batch insertion and upsert' clearly indicates creation and modification of data in a persistent store.

ruvector_insert Rate-limited

ruvector_insert 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.
