## 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 returns information about pull requests in a read-only manner. It performs no mutations, does not execute code, does not delete data, and does not involve financial transactions. The data returned (state, checks, review decision, diff stats, author, labels, etc.) are all informational outputs from querying an existing pull request.

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

## Use case

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

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