Microsoft.Agents.A365.Tooling.Extensions.AgentFramework

Microsoft Agent Framework integration for the Microsoft Agent 365 Tooling SDK. Provides MCP (Model Context Protocol) tool server discovery and registration for agents built with Microsoft.Extensions.AI and Microsoft.Agents.AI.

Installation

dotnet add package Microsoft.Agents.A365.Tooling.Extensions.AgentFramework

Key Features

  • MCP tool discovery — queries the Agent 365 Tooling Gateway and connects to configured MCP servers
  • AddToolServersToAgent — builds an AIAgent with MCP tools loaded alongside any existing tools
  • GetMcpToolsAsync — returns discovered MCP tools as IList<AITool> for manual agent wiring
  • SendChatHistoryAsync — forwards conversation history to the real-time threat-protection endpoint
  • V1/V2 per-audience token support — V1 servers share the ATG token; V2 servers (distinct audience) receive audience-scoped OBO tokens automatically
  • Dev-mode support — tokens sourced from environment variables when ASPNETCORE_ENVIRONMENT=Development

Service Registration

using Microsoft.Agents.A365.Tooling.Extensions.AgentFramework.Extensions;

// Program.cs
builder.Services.AddMcpServices();

AddMcpServices() registers:

  • IMcpToolServerConfigurationService → McpToolServerConfigurationService (scoped)
  • IMcpToolRegistrationService → McpToolRegistrationService (scoped)

Usage

Adding MCP tools to an agent

using Microsoft.Agents.A365.Tooling.Extensions.AgentFramework.Services;
using Microsoft.Agents.Builder.App.UserAuth;
using Microsoft.Extensions.AI;

public class MyActivityHandler : ActivityHandler
{
    private readonly IMcpToolRegistrationService _mcpTools;
    private readonly IChatClient _chatClient;

    public MyActivityHandler(IMcpToolRegistrationService mcpTools, IChatClient chatClient)
    {
        _mcpTools = mcpTools;
        _chatClient = chatClient;
    }

    protected override async Task OnMessageActivityAsync(ITurnContext<IMessageActivity> turnContext, CancellationToken cancellationToken)
    {
        var userAuth = turnContext.Activity.GetUserAuthorization();

        var agent = await _mcpTools.AddToolServersToAgent(
            chatClient: _chatClient,
            agentInstructions: "You are a helpful assistant.",
            initialTools: [],
            agentUserId: turnContext.Activity.From.Id,
            userAuthorization: userAuth,
            authHandlerName: "default",
            turnContext: turnContext);

        var response = await agent.CompleteAsync(turnContext.Activity.Text, cancellationToken: cancellationToken);
        await turnContext.SendActivityAsync(response.Message.Text, cancellationToken: cancellationToken);
    }
}

Retrieving tools without building an agent

IList<AITool> tools = await _mcpTools.GetMcpToolsAsync(
    agentUserId: turnContext.Activity.From.Id,
    userAuthorization: userAuth,
    authHandlerName: "default",
    turnContext: turnContext);

Sending chat history

// From a list of ChatMessage objects
OperationResult result = await _mcpTools.SendChatHistoryAsync(chatMessages, turnContext, cancellationToken);

Authentication

Production

Token acquisition is automatic. The service uses the Agent Framework UserAuthorization and authHandlerName parameters to perform agentic OBO token exchange via AgenticMcpTokenProvider.

  • V1 servers (no audience field, or audience matches the ATG App ID) — receive the shared ATG-scoped token.
  • V2 servers (audience identifies a different application) — receive a token scoped to {audience}/{scope} or {audience}/.default.

Local development

Set ASPNETCORE_ENVIRONMENT=Development (or DOTNET_ENVIRONMENT=Development). Tokens are read from environment variables instead of the OBO flow:

Variable Purpose
BEARER_TOKEN_<SERVERNAME> Per-server token (hyphens in name replaced with underscores, uppercased)
BEARER_TOKEN Shared fallback token for all servers

Example: for a server named my-mcp-server, set BEARER_TOKEN_MY_MCP_SERVER.

Environment Variables

Variable Purpose Default
ASPNETCORE_ENVIRONMENT or DOTNET_ENVIRONMENT Set to Development to enable dev mode —
MCP_PLATFORM_ENDPOINT Override the Tooling Gateway base URL https://agent365.svc.cloud.microsoft
BEARER_TOKEN_<SERVERNAME> Dev-mode per-server Bearer token —
BEARER_TOKEN Dev-mode shared Bearer token fallback —
