AI agents call getDeploymentFileContents to retrieve information from Vercel 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 without side effects. It is a read-only operation that queries existing data. No resources are created, modified, deleted, or executed. The severity is low because reading file contents from an already-deployed application poses minimal risk even if misused by an agent—it cannot alter infrastructure, execute code, or commit financial transactions.
From the tool's definition Tool name 'getDeploymentFileContents' and description 'Gets deployment file contents' indicate a retrieval operation with no modification, deletion, or execution of code.

Register the Vercel MCP server in PolicyLayer and add a rule for getDeploymentFileContents: 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. Nothing to install.
getDeploymentFileContents 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 getDeploymentFileContents 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 getDeploymentFileContents. 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.
getDeploymentFileContents is provided by the Vercel MCP server (ozztec/vercel-api-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
