Methods

AddReplMcpServer(IServiceCollection, Action<ReplMcpServerOptions>?)

public static IServiceCollection AddReplMcpServer(this IServiceCollection services, Action<ReplMcpServerOptions>? configure = null)

Parameters

• services (IServiceCollection): Service collection.
• configure (Action<ReplMcpServerOptions>): Optional configuration callback.

Returns

IServiceCollection - The same service collection.

BuildMcpServerOptions(ICoreReplApp, Action<ReplMcpServerOptions>?, IServiceProvider?)

Builds McpServerOptions from the Repl app’s command graph. Use this to integrate with custom transports (WebSocket, HTTP) or ASP.NET Core without going through the mcp serve CLI command. The returned options capture the current command graph as pre-populated collections.

public static McpServerOptions BuildMcpServerOptions(this ICoreReplApp app, Action<ReplMcpServerOptions>? configure = null, IServiceProvider? services = null)

Parameters

• app (ICoreReplApp): The core Repl app.
• configure (Action<ReplMcpServerOptions>): Optional MCP configuration callback.
• services (IServiceProvider): Optional service provider for DI during tool dispatch.

Returns

McpServerOptions - Ready-to-use McpServerOptions for McpServer.Create or ASP.NET integration.

BuildMcpServerOptions(ReplApp, Action<ReplMcpServerOptions>?)

Builds McpServerOptions from a ReplApp’s command graph, automatically using the app’s shared service provider for DI during tool dispatch. Use this to integrate with custom transports (WebSocket, HTTP) or ASP.NET Core without going through the mcp serve CLI command.

public static McpServerOptions BuildMcpServerOptions(this ReplApp app, Action<ReplMcpServerOptions>? configure = null)

Parameters

• app (ReplApp): The Repl app.
• configure (Action<ReplMcpServerOptions>): Optional MCP configuration callback.

Returns

Enables MCP server mode via {commandName} serve.

public static ReplApp UseMcpServer(this ReplApp app, Action<ReplMcpServerOptions>? configure = null)

Parameters

• app (ReplApp): Target Repl app.
• configure (Action<ReplMcpServerOptions>): Optional configuration callback.

Returns

ReplApp - The same app instance.
