What vault_container_verify does on 0nmcp
AI agents call vault_container_verify to retrieve information from 0nmcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why vault_container_verify is rated Low
Verification operations are reconnaissance in nature: they query state without causing side effects. Unless the tool performs destructive checks (like test deletes), a verify operation is classified as Read with low severity since it cannot compromise data or systems by itself.
From the tool's definition Tool name 'vault_container_verify' and description 'Verify a 0nVault container' indicate a verification/inspection operation. The verb 'verify' implies checking the integrity or status of a container without modifying or executing code—a read-only operation.
Attacks that exploit this kind of access
The rule that runs vault_container_verify safely
PolicyLayer is an MCP gateway: it sits between your AI agents and 0nmcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For vault_container_verify, this is the rule to start with:
vault_container_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 0nmcp, apply this rule, and every vault_container_verify call is checked against it from then on.
Questions about vault_container_verify
Verify a 0nVault container. It is categorised as a Read tool in the 0nmcp MCP Server, which means it retrieves data without modifying state.
Register the 0n MCP server in PolicyLayer and add a rule for vault_container_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 0nmcp. Nothing to install.
vault_container_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 vault_container_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 vault_container_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.
vault_container_verify is provided by the 0n MCP server (0nmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
