Parameters from the server's own tool schema.
This tool queries and returns information about existing Vercel deployments. It performs a read-only operation that retrieves deployment data without side effects, making it a Read category tool with low severity since unauthorized access to deployment history has limited blast radius compared to tools that could modify or delete deployments.
From the tool's definition Tool name contains 'list' and description states 'List Vercel deployments for a project' — a retrieval operation with no modification or execution of deployments.
