AI agents call vercel_get_env to retrieve information from UnClick without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
api_key | string | — | |
decrypt | boolean | — | |
team_id | string | — | |
projectId | string | — | Legacy alias for project_id. |
project_id | string | Yes |
Parameters from the server's own tool schema.
This tool retrieves environment variables, which is a query/fetch operation with no side effects. However, severity is marked 'high' because environment variables in Vercel projects often contain secrets (API keys, database credentials, authentication tokens), and unauthorized access could enable lateral attacks, credential compromise, or further exploitation of infrastructure.
From the tool's definition Tool name 'vercel_get_env' and description 'Get environment variables for a Vercel project' indicate retrieval of configuration data without modification. The verb 'Get' denotes a read-only operation.
Risk signalsHandles credentials or secrets (api_key)
Attacks that exploit this kind of access
Get environment variables for a Vercel project. It is categorised as a Read tool in the UnClick MCP Server, which means it retrieves data without modifying state.
vercel_get_env accepts 5 parameters: api_key, decrypt, team_id, projectId, project_id. Required: project_id. The full parameter table on this page comes from the server's own tool schema.
Register the UnClick MCP server in PolicyLayer and add a rule for vercel_get_env: 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 UnClick. Nothing to install.
vercel_get_env 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_get_env 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_get_env. 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_get_env is provided by the UnClick MCP server (@unclick/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
