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

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

## Why pr-close is rated Medium

The tool modifies PR state (Write category) and optionally deletes branches. While branch deletion is destructive, the primary action is state modification of the PR itself, which is reversible. This is categorized as Write rather than Destructive because PR closure is not irreversible—PRs can be reopened.

From the tool's own definition: "Tool description states it 'Closes a pull request' and includes 'optional branch deletion'. Closing a PR is a state modification that is reversible (PRs can be reopened), while branch deletion is a destructive action."

## Use case

AI agents use pr-close 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-close": {
      "limits": [
        {
          "counter": "pr-close_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
