- Parameters: 0
- Recommended policy verdict: Rate-limited

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

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

## Why assign_instances is rated Medium

This tool modifies instance properties by reassigning them to different placement groups, which is a state change operation. It is reversible (instances can be reassigned to other groups or removed), so it does not qualify as Destructive.

From the tool's own definition: "Tool name 'assign_instances' with description 'Assign Linode instances to a placement group' indicates modification of instance configuration/placement settings. This is a reversible configuration change that modifies resource state without deletion."

## Use case

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

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "assign_instances": {
      "limits": [
        {
          "counter": "assign_instances_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
