Showing your status

The player may not have enabled your plugin yet, or may have suspended it. GetStatus() tells you, so you can say so in your own UI:

var status = mcp.GetStatus();
var hint = status.State switch
{
    McpPluginState.Unavailable =>
        "XIV MCP is not installed.",
    McpPluginState.Undecided =>
        "Enable My Plugin in /xivmcp → Third-party plugins " +
        "to use it from your assistant.",
    McpPluginState.KeptDisabled =>
        "You kept My Plugin disabled in XIV MCP.",
    McpPluginState.AwaitingConsent =>
        "My Plugin has new features; " +
        "confirm them in /xivmcp → Third-party plugins.",
    McpPluginState.Suspended =>
        $"XIV MCP suspended My Plugin: {status.SuspendReason}",
    _ => null,   // Enabled
};

var canBuy = status.Capabilities
    .GetValueOrDefault(McpCapabilities.SpendGil) != McpPermission.Deny;

The states McpPluginState reports, and what moves your plugin between them.

Call it when your window opens or before a step, not every frame. Do not cache it: the player can change settings at any time.

State	Meaning
`Unavailable`	XIV MCP is not loaded, or is older than the API version of your copy of the client.
`Undecided`	The player has not enabled your plugin yet (the default).
`KeptDisabled`	The player chose Keep disabled.
`Enabled`	Your tools are offered.
`AwaitingConsent`	Your registration grew; all your tools pause until the player consents again.
`Suspended`	A call did something undeclared. `SuspendReason` says what.
