AI agents call vercel_deployments to retrieve information from Access 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 query of deployment metadata. It retrieves and displays deployment information without creating, modifying, deleting, or executing anything. The optional filtering does not change the read-only nature.
From the tool's definition Tool explicitly 'list[s] recent Vercel deployments with their status, URL, branch, and creation time' and optionally filter[s] by project'. Action verbs are informational—list, check, find—with no modification, deletion, or code execution.
Attacks that exploit this kind of access
List recent Vercel deployments with their status, URL, branch, and creation time. Optionally filter by project. Use this to check deployment status or find a deployment ID for vercel_build_logs. It is categorised as a Read tool in the Access MCP Server, which means it retrieves data without modifying state.
Register the Access MCP server in PolicyLayer and add a rule for vercel_deployments: 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 Access. Nothing to install.
vercel_deployments 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 vercel_deployments 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 vercel_deployments. 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.
vercel_deployments is provided by the Access MCP server (scottpedia0/access). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
