AI agents use ruvector_create_index to create or update resources in Ruflo — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ruflo environment.
This tool creates (writes) a vector index artifact for search optimization. While it modifies system state by adding an index, the operation is reversible—indices can be deleted or recreated without permanent data loss. It does not execute arbitrary code, delete irreversibly, or move money. Classified as Write rather than Execute because it is a specific data structure creation, not arbitrary code execution.
From the tool's definition Tool name 'ruvector_create_index' and description 'Create a vector index' indicate creation of a new data structure. The description explicitly states the action is to 'Create' an index, which is a reversible modification operation.
Attacks that exploit this kind of access
Create a vector index (HNSW or IVF) for faster similarity search. It is categorised as a Write tool in the Ruflo MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Ruflo MCP server in PolicyLayer and add a rule for ruvector_create_index: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Ruflo. Nothing to install.
ruvector_create_index is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the ruvector_create_index rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for ruvector_create_index. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
ruvector_create_index is provided by the Ruflo MCP server (ruvnet/ruflo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
ruvector_create_index is one line of Ruflo's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
