What rvf_verify does on Claude Flow
AI agents call rvf_verify to retrieve information from Claude Flow without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why rvf_verify is rated Low
Verification operations are read-like queries that check state or properties of a target (here, an RVF container). No data is created, modified, deleted, or executed based on the description. The sibling tools include spawn/terminate/update operations that are more severe; this tool's verify function is constrained to information retrieval about container state.
From the tool's definition Tool name 'rvf_verify' and description 'Verify RVF container' indicate a verification/inspection operation with no modification capability. The verb 'verify' typically implies validation or status checking without side effects.
Attacks that exploit this kind of access
The rule that runs rvf_verify 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 rvf_verify, this is the rule to start with:
rvf_verify 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 Claude Flow, apply this rule, and every rvf_verify call is checked against it from then on.
Questions about rvf_verify
Verify RVF container. It is categorised as a Read tool in the Claude Flow MCP Server, which means it retrieves data without modifying state.
Register the Claude Flow MCP server in PolicyLayer and add a rule for rvf_verify: 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 Claude Flow. Nothing to install.
rvf_verify is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the rvf_verify 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 rvf_verify. 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.
rvf_verify is provided by the Claude Flow MCP server (claude-flow). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
