List deployments under the authenticated user or team
AI agents call list_deployment 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 data retrieval operation. It lists existing deployments but does not create, modify, delete, execute code, or trigger external operations. The action is purely informational with no side effects, making it a Read category risk. Severity is low because listing deployments exposes metadata about infrastructure but does not enable direct operational changes or data destruction.
From the tool's definition Tool name 'list_deployment' and description 'List deployments under the authenticated user or team' indicate a read-only operation that retrieves/queries deployment data without modification or side effects.
Documented attack patterns abuse exactly the kind of access list_deployment 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:
{
"version": "1",
"default": "deny",
"tools": {
"list_deployment": {}
}
}list_deployment is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List deployments under the authenticated user or team. 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: 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 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 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. 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 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.
