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

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

## Why package-update is rated Medium

The tool creates or modifies dependency specifications in Swift package manifests (Package.swift), which is a Write category action. Severity is medium because unvetted package updates could introduce vulnerable dependencies or breaking changes, but the operation is reversible (dependencies can be rolled back).

From the tool's own definition: "Tool name 'package-update' combined with description 'Updates Swift package dependencies' indicates modification of project dependencies. This is a reversible write operation that alters project configuration files."

## Use case

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

## Recommended policy (PolicyLayer)

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

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