AI agents call list to retrieve information from Myvtp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns information about deployed applications without creating, modifying, deleting, or executing any operations. It is explicitly documented as a pre-deployment check mechanism, confirming its read-only nature. The blast radius is minimal—the AI agent can only gain visibility into existing deployments.
From the tool's definition Tool name 'list' and description 'List all deployed apps with their status and URLs' indicates a read-only retrieval operation with no side effects.
Attacks that exploit this kind of access
List all deployed apps with their status and URLs. Call before deploying to check if an app already exists. It is categorised as a Read tool in the Myvtp MCP Server, which means it retrieves data without modifying state.
Register the Myvtp MCP server in PolicyLayer and add a rule for list: 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 Myvtp. Nothing to install.
list 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 list 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 list. 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.
list is provided by the Myvtp MCP server (myvtp/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
