Verify RVF container
AI agents call rvf_verify to retrieve information from Claude Flow without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
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
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.
