# MentorAgentBlazorOptions class > Configuration for AddMentorAgentBlazor(). Provides UI settings for the chat widget and the SignalR hub URL. - URL: https://docs.mentoragent.net/api/novior-mentoragent-blazor-models/mentoragentblazoroptions - Verified with: MentorAgent 1.2.0 - Last updated: 2026-10-27 - Packages: Novior.MentorAgent.Blazor ## Definition Namespace: `Novior.MentorAgent.Blazor.Models`. Package: `Novior.MentorAgent.Blazor`. `public sealed class MentorAgentBlazorOptions` ```shell dotnet add package Novior.MentorAgent.Blazor ``` ## Constructors `public MentorAgentBlazorOptions()` ## Properties ### `AccessTokenProvider` `public Func>? AccessTokenProvider { get; set; }` Supplies the bearer token for the hub connection, called on every connect and reconnect. **Without this the hub sees an anonymous caller**, whatever your application has signed the user in as — which means every `RequiredRoles` action is blocked and the user is keyed as anonymous: with the server's `AnonymousIdentity = PerSession`, the default, memory and `RateLimitPerUser` last only as long as the connection; with `Shared` every user shares the single memory key `"anonymous"` and one global limit. This is the WASM equivalent of the JavaScript client's `accessTokenFactory`, and the server reads the resulting principal off `HubCallerContext.User`. Return `null` while nobody is signed in; the connection then behaves exactly as it did before a provider was set. ```text title="Example" builder.Services.AddSingleton(); builder.Services.AddMentorAgentBlazor(options => { options.HubUrl = "https://api.example.com/mentor-hub"; options.AccessTokenProvider = () => Task.FromResult(tokenStore.Token); }); ``` ### `AiDisclosureMessage` `public string? AiDisclosureMessage { get; set; }` The notice's text, shown as written. If null, uses the localized default in [`MentorAgentBlazorOptions.Language`](https://docs.mentoragent.net/api/novior-mentoragent-blazor-models/mentoragentblazoroptions#language). ### `AllowedImageTypes` `public List AllowedImageTypes { get; set; }` Client-side MIME allow-list for attachments. ### `AvatarUrl` `public string? AvatarUrl { get; set; }` Custom avatar URL. ### `BotName` `public string BotName { get; set; }` Bot name shown in the widget header. ### `ConfigureConnection` `public Action? ConfigureConnection { get; set; }` Escape hatch applied to the hub's `HttpConnectionOptions` after [`MentorAgentBlazorOptions.AccessTokenProvider`](https://docs.mentoragent.net/api/novior-mentoragent-blazor-models/mentoragentblazoroptions#accesstokenprovider) — custom headers, a transport restriction, cookies, `UseDefaultCredentials`. Use it for anything the options above do not name. ```text title="Example" options.ConfigureConnection = o => o.Headers["X-Tenant"] = tenantId; ``` ### `EnableImageInput` `public bool EnableImageInput { get; set; }` Show the image-attachment button and enable paste / drag-and-drop / URL input (roadmap \#13). Must also be enabled server-side (`MentorOptions.EnableImageInput`), which is where attachments are actually validated. ### `EnableOnboardingTour` `public bool EnableOnboardingTour { get; set; }` Show the guided tour on first run (roadmap \#18). Default: false. ### `EnableSuggestions` `public bool EnableSuggestions { get; set; }` Show suggestion chips in the welcome panel. ### `EnableVoiceInput` `public bool EnableVoiceInput { get; set; }` Show microphone button for voice input. ### `EnableVoiceOutput` `public bool EnableVoiceOutput { get; set; }` Enable text-to-speech for AI responses. ### `HasMcpServers` `public bool HasMcpServers { get; set; }` Whether the server has MCP servers configured (enables the MCP badge). ### `HasRemoteAgents` `public bool HasRemoteAgents { get; set; }` Whether the server has remote A2A agents configured (enables the A2A badge). ### `HostedTools` `public MentorHostedTools HostedTools { get; set; }` Hosted tools active on the server (roadmap \#15), used to fill the badge. Mirror whatever `MentorOptions.HostedTools` is set to on the Novior.MentorAgent.Server project. ### `HubUrl` `public string HubUrl { get; set; }` URL of the Novior.MentorAgent.Server SignalR hub. Default: "/mentor-hub". A relative URL is resolved against the page's base address, as a browser does ("/mentor-hub" against the origin, "mentor-hub" under the app's base path): use it when the server also serves the client. For a server on another origin, set its absolute URL. ### `InputPlaceholder` `public string? InputPlaceholder { get; set; }` Input box placeholder text. If null, uses the localized default in [`MentorAgentBlazorOptions.Language`](https://docs.mentoragent.net/api/novior-mentoragent-blazor-models/mentoragentblazoroptions#language). ### `Language` `public MentorLanguage Language { get; set; }` Language for widget UI strings. ### `MaxImageBytes` `public int MaxImageBytes { get; set; }` Client-side size cap per image, in bytes. Default: 4 MB. ### `MaxImagesPerMessage` `public int MaxImagesPerMessage { get; set; }` Client-side cap on images per message. Default: 4. ### `McpServerNames` `public List McpServerNames { get; set; }` Names of MCP client servers configured on the server. Used to pre-populate the MCP status badge. ### `Position` `public ChatPosition Position { get; set; }` Widget position on screen. ### `PrimaryColor` `public string? PrimaryColor { get; set; }` Custom accent color (hex, e.g. "\#7c3aed"). ### `RemoteAgentDisplays` `public List RemoteAgentDisplays { get; set; }` Remote A2A agents to display in the A2A badge and detail bar. ### `ShowA2AStatus` `public bool ShowA2AStatus { get; set; }` Show A2A remote agent status badge in the widget header. ### `ShowAiDisclosure` `public bool ShowAiDisclosure { get; set; }` Shows, under the header, the notice that tells people they are talking to an AI assistant, for the whole conversation. Default: true. The marker on each reply (`data-ai-generated`) stays either way. ### `ShowHostedToolsStatus` `public bool ShowHostedToolsStatus { get; set; }` Show the provider-hosted tools badge in the widget header (roadmap \#15). Purely informational — the tools themselves are configured and executed server-side. ### `ShowMcpStatus` `public bool ShowMcpStatus { get; set; }` Show MCP server connection status badge in the widget header. ### `ShowRagSources` `public bool ShowRagSources { get; set; }` Show RAG source citations below AI responses. ### `Theme` `public MentorTheme Theme { get; set; }` Visual theme. ### `TourUrl` `public string TourUrl { get; set; }` Where to fetch the tour steps from (roadmap \#18). Default: `/mentor/tour`. A relative value is resolved against [`MentorAgentBlazorOptions.HubUrl`](https://docs.mentoragent.net/api/novior-mentoragent-blazor-models/mentoragentblazoroptions#huburl)'s origin when that is absolute, because the tour is served by the same server as the hub — resolving it against the client app's own address instead would request it from a host that does not have it. Set an absolute URL here to override that entirely. ### `VoiceBargeIn` `public bool VoiceBargeIn { get; set; }` Stop playback when the user presses the microphone or sends a message (roadmap \#17). Default: true. ### `VoiceHandsFree` `public bool VoiceHandsFree { get; set; }` Hands-free loop — send on silence, reopen the microphone after the answer (roadmap \#17). Default: false. ### `VoiceRate` `public double VoiceRate { get; set; }` Speech rate for `SpeechSynthesisUtterance` (0.5–2.0). Default: 1.0. ### `VoiceStreaming` `public bool VoiceStreaming { get; set; }` Speak each sentence as it streams instead of reading the answer back (roadmap \#17). Default: true. ### `WelcomeMessage` `public string? WelcomeMessage { get; set; }` Welcome message shown when the chat is empty. --- - Previous: [MentorHubClient class](https://docs.mentoragent.net/api/novior-mentoragent-blazor-hub/mentorhubclient.md) - Next: [WasmMentorOrchestrator class](https://docs.mentoragent.net/api/novior-mentoragent-blazor-services/wasmmentororchestrator.md)
