Retrieves all Aliases for the Deployment with the given ID
AI agents call list_deployment_aliases to retrieve information from Vercel MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation that queries and returns alias data associated with a deployment. No data is modified, created, deleted, or executed. The blast radius is minimal as misuse would only expose existing alias information without enabling further harmful actions.
From the tool's definition Tool name 'list_deployment_aliases' and description 'Retrieves all Aliases for the Deployment with the given ID' indicate a query/retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access list_deployment_aliases gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Vercel MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_deployment_aliases:
{
"version": "1",
"default": "deny",
"tools": {
"list_deployment_aliases": {}
}
}list_deployment_aliases is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Retrieves all Aliases for the Deployment with the given ID. It is categorised as a Read tool in the Vercel MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Vercel MCP Server MCP server in PolicyLayer and add a rule for list_deployment_aliases: 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 Vercel MCP Server. Nothing to install.
list_deployment_aliases 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_deployment_aliases 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_deployment_aliases. 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_deployment_aliases is provided by the Vercel MCP Server MCP server (quegenx/vercel-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
