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

```json
{
  "jsonrpc": "2.0",

    "name": "pr-update",
    "arguments": {}

## Why pr-update is rated Medium

This tool creates or modifies data in a reversible manner. While it alters PR metadata on a version control system, these changes can be undone (labels removed, assignees changed back, titles reverted, etc.). It does not delete data irreversibly, execute arbitrary code, or trigger financial transactions.

From the tool's own definition: "Tool description explicitly states it 'Updates pull request metadata (title, body, labels, assignees, reviewers, milestone, base branch, projects)', which are reversible modifications to PR data structures."

## Use case

AI agents use pr-update to create or update resources in Go, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Go environment.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "pr-update": {
      "limits": [
        {
          "counter": "pr-update_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
