## Facts

- Tool: `pr-view`
- Server: Npm (`Dave-London/Pare`) — https://policylayer.com/tools/io-github-dave-london-npm.md
- Homepage: https://github.com/Dave-London/pare
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Allowed

## 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 without any side effects. It performs a passive read operation, returning information about a PR's state and metadata. This is a classic Read category tool with minimal security risk, assuming it only returns information already accessible to the authenticated user.

From the tool's own definition: "Tool description explicitly states it 'Views a pull request' and 'Returns structured data' with read-only information (state, checks, review decision, diff stats, author, labels, etc.). No modification, deletion, or execution capabilities are mentioned."

## Use case

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

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