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

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

## Why pr-view is rated Low

This tool retrieves and queries pull request metadata and state information without creating, modifying, deleting, or executing any operations. It is a straightforward data retrieval function with no side effects, matching the Read category definition.

From the tool's own definition: "Tool name is 'pr-view' and description states it 'Views a pull request' and 'Returns structured data' — core read operation with no modification or execution capabilities."

## Use case

AI agents call pr-view to retrieve information from Github 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 Github:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "pr-view": {}
  }
}
```
