AI agents call get_deployment_file 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 retrieves file contents from a deployment, which is a read-only operation with no side effects. It does not create, modify, delete, execute, or move resources. The blast radius is minimal—an agent could only access deployment file information it already has authorization to view.
From the tool's definition Tool name 'get_deployment_file' and description 'Get contents of a specific deployment file' indicate a retrieval operation with no modification or execution of code.
Documented attack patterns abuse exactly the kind of access get_deployment_file 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 get_deployment_file:
{
"version": "1",
"default": "deny",
"tools": {
"get_deployment_file": {}
}
}get_deployment_file is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get contents of a specific deployment file. 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 get_deployment_file: 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.
get_deployment_file 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 get_deployment_file 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 get_deployment_file. 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.
get_deployment_file 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.
