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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "select-account",
    "arguments": {
      "account": "<account>"
    }
  }
}
```

## Why select-account is rated Medium

This tool performs a state-changing operation that affects subsequent tool behavior by designating which Microsoft account context will be used for future operations. This is a Write operation because it modifies configuration state reversibly.

From the tool's own definition: "The tool 'select-account' modifies state by setting a default account selection. While it does not create or delete accounts, it changes the application's configured state (which account is active/default), which is a reversible data modification."

## Use case

AI agents use select-account to create or update resources in Ms 365, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ms 365 environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Ms 365:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "select-account": {
      "limits": [
        {
          "counter": "select-account_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
