What rvf_extract does on Ruflo
AI agents call rvf_extract to retrieve information from Ruflo without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why rvf_extract is rated Low
The tool appears to retrieve or query RVF data without modifying, deleting, or executing operations. No side effects are indicated. However, confidence is moderate rather than high because 'RVF' is not clearly defined in the provided context, and the description lacks detail about what RVF represents and whether extraction might trigger any external operations or state changes in the Ruflo swarm system.
From the tool's definition Tool name 'rvf_extract' and description 'Extract RVF contents' indicate retrieval/extraction of data from RVF (likely a file or data format). The verb 'extract' combined with 'contents' suggests read-only access to data without modification.
Attacks that exploit this kind of access
The rule that runs rvf_extract safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Ruflo, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For rvf_extract, this is the rule to start with:
rvf_extract is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Ruflo, apply this rule, and every rvf_extract call is checked against it from then on.
