## Example call (MCP tools/call, JSON-RPC 2.0)

```json

  "jsonrpc": "2.0",

## Why vercel_list_environment_variables is rated Low

The tool retrieves/lists environment variables from Vercel, which is a read operation with no side effects. However, environment variables often contain sensitive data (API keys, secrets, database credentials), so the severity is medium due to potential information exposure if accessed by an unauthorized agent.

From the tool's own definition: "Tool name 'vercel_list_environment_variables' indicates retrieval of environment variables. The 'list' action is a read-only operation that queries existing data without modification."

## Use case

AI agents call vercel_list_environment_variables to retrieve information from Integrations MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Integrations MCP:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "vercel_list_environment_variables": {}
  }
}
```
