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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "variable-list",
    "arguments": {}
  }
}
```

## Why variable-list is rated Low

This tool retrieves and displays GitHub Actions variables, which are primarily read-only operations. No data is created, modified, or deleted. The medium severity reflects that exposed variables could include secrets, API keys, or other sensitive configuration data that an AI agent could extract and exfiltrate, even though the tool itself performs only data retrieval.

From the tool's own definition: "Tool description states it 'Lists repository, organization, or environment GitHub Actions variables with values and metadata.' The word 'Lists' indicates data retrieval with no modification."

## Use case

AI agents call variable-list to retrieve information from Lint 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 Lint:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "variable-list": {}
  }
}
```
