Microsoft Teams ChatGPT Integration: Enterprise Collaboration Guide

Deploy ChatGPT across enterprise Teams channels for secure, compliant AI collaboration. Organizations report 40% improvement in cross-team knowledge sharing and faster decision cycles when integrating AI assistants into their Microsoft 365 ecosystem. This comprehensive guide covers Azure AD authentication, Bot Framework SDK implementation, messaging extensions, and enterprise-grade security configurations.

Why Integrate ChatGPT with Microsoft Teams

Microsoft Teams serves as the collaboration hub for over 280 million monthly active users, making it the ideal platform for enterprise AI deployment. Integrating ChatGPT directly into Teams channels eliminates context switching, centralizes knowledge management, and leverages existing security infrastructure.

Enterprise Use Cases:

• Meeting Intelligence: Automatically summarize Teams meetings, extract action items, and generate follow-up tasks from transcripts
• Document Q&A: Query SharePoint documents, OneDrive files, and Teams files using natural language through the Microsoft Graph API
• Project Insights: Analyze Planner tasks, Project timelines, and team activity to surface bottlenecks and recommendations
• Compliance Assistance: Draft policy-compliant communications, review contracts against templates, and answer HR/legal questions

Technical Advantages:

• Single Sign-On (SSO): Azure AD authentication eliminates separate login credentials and enforces conditional access policies
• Microsoft Graph API: Access Teams messages, calendar events, SharePoint content, and user profiles programmatically
• Data Residency: Deploy bot infrastructure in Microsoft data centers matching your organization's compliance requirements (EU, US, Asia)
• Enterprise Security: Leverage existing DLP policies, information protection labels, and eDiscovery capabilities

Business Impact: IT teams report 60% reduction in support tickets when ChatGPT bots handle common employee questions about policies, benefits, and IT procedures directly within Teams.

Prerequisites for Enterprise Integration

Before implementing ChatGPT in Microsoft Teams, ensure your organization meets these technical requirements:

Microsoft 365 Subscription:

• Microsoft 365 E3 or E5 (required for advanced Graph API permissions)
• Teams Premium (optional, for meeting transcription features)
• Azure subscription (for bot hosting and resource provisioning)

Administrative Access:

• Azure Active Directory global admin or application admin role
• Teams admin center access for app upload and policy configuration
• SharePoint admin access (if integrating document search)

Development Environment:

• Node.js 18+ or Python 3.9+
• Bot Framework SDK 4.x
• Teams Toolkit for Visual Studio Code (recommended)
• Azure CLI for deployment automation

Network and Security:

• Firewall rules allowing outbound HTTPS to botframework.com (port 443)
• Azure AD conditional access policies reviewed for service principals
• Data Loss Prevention (DLP) policies configured for bot conversations

Permissions Required:

• User.Read (basic profile access)
• Team.ReadBasic.All (team membership and channels)
• Files.Read.All (SharePoint and OneDrive document access, optional)
• Chat.Read (conversation history, if needed)

Implementation Guide: Step-by-Step Integration

Step 1: Register Azure AD Application

Every Teams bot requires an Azure AD application registration for identity and OAuth authentication. This registration provides the credentials your bot uses to authenticate with Microsoft services.

Registration Process:

1. Navigate to Azure Portal → Azure Active Directory → App registrations

2. Click "New registration"

3. Configure application:

   • Name: ChatGPT Teams Bot
   • Supported account types: Accounts in this organizational directory only (Single tenant)
   • Redirect URI: https://token.botframework.com/.auth/web/redirect

4. After registration, note the Application (client) ID and Directory (tenant) ID

5. Create client secret:

   • Navigate to "Certificates & secrets"
   • Click "New client secret"
   • Set expiration (24 months recommended for production)
   • Copy the secret value immediately (it won't be shown again)

Configure API Permissions:

{
  "requiredResourceAccess": [
    {
      "resourceAppId": "00000003-0000-0000-c000-000000000000",
      "resourceAccess": [
        {
          "id": "e1fe6dd8-ba31-4d61-89e7-88639da4683d",
          "type": "Scope"
        },
        {
          "id": "660b7406-55f1-41ca-a0ed-0b035e182f3e",
          "type": "Scope"
        },
        {
          "id": "df85f4d6-205c-4ac5-a5ea-6bf408dba283",
          "type": "Scope"
        }
      ]
    }
  ]
}

This configuration grants:

• User.Read (e1fe6dd8): Read user profile
• Team.ReadBasic.All (660b7406): Access team information
• Files.Read.All (df85f4d6): Query SharePoint documents

Grant Admin Consent: Click "Grant admin consent for [Your Organization]" to authorize these permissions tenant-wide.

Step 2: Create Teams App Manifest

The Teams app manifest (manifest.json) defines your bot's capabilities, supported features, and integration points. This JSON file is packaged with icon assets and uploaded to Teams.

Complete Teams Manifest (manifest.json):

{
  "$schema": "https://developer.microsoft.com/json-schemas/teams/v1.16/MicrosoftTeams.schema.json",

}

Manifest Components Explained:

• bots: Defines bot behavior in personal chats, team channels, and group chats. supportsFiles: true enables document uploads.
• composeExtensions: Messaging extensions for search and actions. The searchDocuments command queries SharePoint via Microsoft Graph.
• messageHandlers: Link unfurling for SharePoint/Office URLs (automatically expand links with rich previews).
• webApplicationInfo: Enables SSO by linking the Azure AD app resource URI.

Icon Requirements: Include 32x32px outline.png and 192x192px color.png in your app package.

Step 3: Build Bot with Bot Framework SDK

The Bot Framework SDK handles conversation logic, activity processing, and integration with your MCP server (ChatGPT backend).

Bot Adapter Implementation (Node.js):

const { BotFrameworkAdapter, ConversationState, MemoryStorage, UserState } = require('botbuilder');
const { TeamsActivityHandler, CardFactory, TurnContext } = require('botbuilder');
const axios = require('axios');

// Initialize Bot Framework Adapter
const adapter = new BotFrameworkAdapter({
  appId: process.env.MICROSOFT_APP_ID,
  appPassword: process.env.MICROSOFT_APP_PASSWORD
});

// Error handling middleware
adapter.onTurnError = async (context, error) => {
  console.error(`[onTurnError] ${error}`);
  await context.sendActivity('The bot encountered an error or bug.');
  await context.sendActivity('To continue, please restart the conversation.');

  // Send error trace to App Insights
  await conversationState.delete(context);
};

// Conversation state for multi-turn dialogs
const memoryStorage = new MemoryStorage();
const conversationState = new ConversationState(memoryStorage);
const userState = new UserState(memoryStorage);

// Teams Activity Handler
class ChatGPTTeamsBot extends TeamsActivityHandler {
  constructor(conversationState, userState) {
    super();

    this.conversationState = conversationState;
    this.userState = userState;

    // Conversation state property accessors
    this.conversationDataAccessor = conversationState.createProperty('conversationData');
    this.userDataAccessor = userState.createProperty('userData');

    // Handle message activities (user sends text to bot)
    this.onMessage(async (context, next) => {
      const userMessage = context.activity.text.trim();
      const conversationData = await this.conversationDataAccessor.get(context, { history: [] });

      // Check for bot commands
      if (userMessage.startsWith('/summarize')) {
        await this.handleSummarizeCommand(context);
      } else if (userMessage.startsWith('/search')) {
        await this.handleSearchCommand(context, userMessage);
      } else {
        // Regular ChatGPT conversation
        await this.handleChatGPTQuery(context, userMessage, conversationData);
      }

      await next();
    });

    // Handle conversation updates (bot added to team/channel)
    this.onConversationUpdate(async (context, next) => {
      if (context.activity.membersAdded) {
        for (const member of context.activity.membersAdded) {
          if (member.id !== context.activity.recipient.id) {
            const welcomeCard = CardFactory.heroCard(
              'Welcome to ChatGPT Teams Bot',
              'I can help with meeting summaries, document search, and project insights.',
              ['https://makeaihq.com/assets/teams-welcome.png'],
              [
                { type: 'messageBack', title: 'Summarize Last Meeting', text: '/summarize' },
                { type: 'messageBack', title: 'Search Documents', text: '/search' }
              ]
            );
            await context.sendActivity({ attachments: [welcomeCard] });
          }
        }
      }
      await next();
    });

    // Handle Teams-specific invoke activities (messaging extensions, SSO)
    this.onInvokeActivity(async (context) => {
      if (context.activity.name === 'composeExtension/query') {
        return await this.handleMessagingExtensionQuery(context);
      } else if (context.activity.name === 'signin/verifyState') {
        return await this.handleSSOTokenExchange(context);
      }
    });
  }

  // ChatGPT query handler
  async handleChatGPTQuery(context, userMessage, conversationData) {
    await context.sendActivities([{ type: 'typing' }]);

    try {
      // Call MCP server with conversation history
      const response = await axios.post('https://api.makeaihq.com/mcp/chat', {
        messages: [
          ...conversationData.history,
          { role: 'user', content: userMessage }
        ],
        model: 'gpt-4',
        temperature: 0.7,
        max_tokens: 800
      }, {
        headers: { 'Authorization': `Bearer ${process.env.MCP_API_KEY}` }
      });

      const aiResponse = response.data.choices[0].message.content;

      // Update conversation history
      conversationData.history.push(
        { role: 'user', content: userMessage },
        { role: 'assistant', content: aiResponse }
      );

      // Limit history to last 10 messages (memory management)
      if (conversationData.history.length > 20) {
        conversationData.history = conversationData.history.slice(-20);
      }

      await this.conversationDataAccessor.set(context, conversationData);
      await this.conversationState.saveChanges(context);

      await context.sendActivity(aiResponse);

    } catch (error) {
      console.error('MCP API Error:', error);
      await context.sendActivity('Sorry, I encountered an error processing your request. Please try again.');
    }
  }

  // Summarize command handler (Graph API integration)
  async handleSummarizeCommand(context) {
    const teamsChannelId = context.activity.channelData.channel.id;
    const accessToken = await this.getUserAccessToken(context);

    if (!accessToken) {
      await this.sendOAuthCard(context);
      return;
    }

    try {
      // Fetch last 50 messages from channel
      const messagesResponse = await axios.get(
        `https://graph.microsoft.com/v1.0/teams/${context.activity.channelData.team.id}/channels/${teamsChannelId}/messages`,
        {
          headers: { 'Authorization': `Bearer ${accessToken}` },
          params: { '$top': 50 }
        }
      );

      const messages = messagesResponse.data.value
        .map(msg => msg.body.content)
        .join('\n\n');

      // Send to ChatGPT for summarization
      const summaryResponse = await axios.post('https://api.makeaihq.com/mcp/chat', {
        messages: [{
          role: 'user',
          content: `Summarize these Teams channel messages into key points and action items:\n\n${messages}`
        }],
        model: 'gpt-4',
        temperature: 0.5
      });

      await context.sendActivity(summaryResponse.data.choices[0].message.content);

    } catch (error) {
      console.error('Graph API Error:', error);
      await context.sendActivity('Unable to access channel messages. Ensure bot has Team.ReadBasic.All permission.');
    }
  }
}

module.exports.ChatGPTTeamsBot = ChatGPTTeamsBot;

Key Implementation Details:

• Conversation State: Maintains chat history across turns for context-aware responses
• Typing Indicator: Sends typing activity while processing ChatGPT requests (improves UX)
• Error Handling: Graceful degradation with user-friendly error messages
• Command Routing: /summarize and /search trigger specialized handlers vs. general ChatGPT

Step 4: Add Messaging Extension for Document Search

Messaging extensions enable users to search SharePoint documents directly from the Teams compose box or command palette.

Messaging Extension Handler:

async handleMessagingExtensionQuery(context) {
  const searchQuery = context.activity.value.parameters[0].value;
  const accessToken = await this.getUserAccessToken(context);

  if (!accessToken) {
    return {
      composeExtension: {
        type: 'auth',
        suggestedActions: {
          actions: [{
            type: 'openUrl',
            value: await this.getOAuthSignInUrl(context),
            title: 'Sign In'
          }]
        }
      }
    };
  }

  try {
    // Search SharePoint via Microsoft Graph
    const searchResponse = await axios.post(
      'https://graph.microsoft.com/v1.0/search/query',
      {
        requests: [{
          entityTypes: ['driveItem'],
          query: {
            queryString: searchQuery
          },
          from: 0,
          size: 10
        }]
      },
      { headers: { 'Authorization': `Bearer ${accessToken}` } }
    );

    const searchResults = searchResponse.data.value[0].hitsContainers[0].hits;

    // Convert search results to adaptive cards
    const attachments = searchResults.map(hit => {
      const resource = hit.resource;
      return CardFactory.heroCard(
        resource.name,
        resource.summary || 'No preview available',
        [],
        [{
          type: 'openUrl',
          title: 'Open Document',
          value: resource.webUrl
        }]
      );
    });

    return {
      composeExtension: {
        type: 'result',
        attachmentLayout: 'list',
        attachments: attachments
      }
    };

  } catch (error) {
    console.error('Search Error:', error);
    return {
      composeExtension: {
        type: 'message',
        text: 'Search failed. Ensure bot has Files.Read.All permission.'
      }
    };
  }
}

Search Capabilities:

• Queries SharePoint sites, OneDrive, and Teams files
• Returns top 10 results with document preview
• Opens documents directly in Office web apps
• Supports natural language queries (e.g., "budget spreadsheet from last month")

Step 5: Implement SSO Authentication

Single Sign-On eliminates separate login prompts by leveraging the user's existing Azure AD session. This requires OAuth token exchange between Teams and your bot.

SSO Authentication Flow:

const { SimpleGraphClient } = require('./graphClient');

class AuthHelper {
  // Get OAuth sign-in URL
  async getOAuthSignInUrl(context) {
    const redirectUri = `https://token.botframework.com/.auth/web/redirect`;
    const authUrl = `https://login.microsoftonline.com/${process.env.TENANT_ID}/oauth2/v2.0/authorize?` +
      `client_id=${process.env.MICROSOFT_APP_ID}` +
      `&response_type=code` +
      `&redirect_uri=${encodeURIComponent(redirectUri)}` +
      `&response_mode=query` +
      `&scope=${encodeURIComponent('User.Read Team.ReadBasic.All Files.Read.All')}` +
      `&state=${context.activity.from.id}`;

    return authUrl;
  }

  // Send OAuth card to user
  async sendOAuthCard(context) {
    const signInUrl = await this.getOAuthSignInUrl(context);

    const card = CardFactory.oauthCard(
      'Azure AD Login',
      'Sign in to enable document search and meeting summaries',
      signInUrl,
      process.env.MICROSOFT_APP_ID
    );

    await context.sendActivity({ attachments: [card] });
  }

  // Exchange token (silent authentication)
  async getUserAccessToken(context) {
    try {
      // Attempt silent token acquisition
      const tokenResponse = await adapter.getUserToken(
        context,
        process.env.OAUTH_CONNECTION_NAME,
        null // magicCode (null for silent auth)
      );

      return tokenResponse?.token || null;

    } catch (error) {
      console.error('Token Exchange Error:', error);
      return null;
    }
  }

  // Handle SSO token exchange invoke
  async handleSSOTokenExchange(context) {
    const magicCode = context.activity.value?.state;

    if (magicCode) {
      const tokenResponse = await adapter.getUserToken(
        context,
        process.env.OAUTH_CONNECTION_NAME,
        magicCode
      );

      if (tokenResponse?.token) {
        // Token acquired successfully
        await context.sendActivity('Authentication successful! You can now use all bot features.');

        // Store user token in state for future requests
        const userData = await this.userDataAccessor.get(context, {});
        userData.accessToken = tokenResponse.token;
        await this.userDataAccessor.set(context, userData);
        await this.userState.saveChanges(context);
      }
    }
  }
}

// Graph API client wrapper
class SimpleGraphClient {
  constructor(accessToken) {
    this.accessToken = accessToken;
  }

  async getMyProfile() {
    const response = await axios.get(
      'https://graph.microsoft.com/v1.0/me',
      { headers: { 'Authorization': `Bearer ${this.accessToken}` } }
    );
    return response.data;
  }

  async getMyTeams() {
    const response = await axios.get(
      'https://graph.microsoft.com/v1.0/me/joinedTeams',
      { headers: { 'Authorization': `Bearer ${this.accessToken}` } }
    );
    return response.data.value;
  }

  async searchFiles(query) {
    const response = await axios.post(
      'https://graph.microsoft.com/v1.0/search/query',
      {
        requests: [{
          entityTypes: ['driveItem'],
          query: { queryString: query }
        }]
      },
      { headers: { 'Authorization': `Bearer ${this.accessToken}` } }
    );
    return response.data.value[0].hitsContainers[0].hits;
  }
}

module.exports = { AuthHelper, SimpleGraphClient };

Advanced Enterprise Features

Meeting Transcript Summarization

Leverage Microsoft Graph API's meeting transcript feature (requires Teams Premium license):

async summarizeMeeting(context, meetingId) {
  const accessToken = await this.getUserAccessToken(context);

  // Fetch meeting transcript
  const transcriptResponse = await axios.get(
    `https://graph.microsoft.com/beta/users/${context.activity.from.aadObjectId}/onlineMeetings/${meetingId}/transcripts`,
    { headers: { 'Authorization': `Bearer ${accessToken}` } }
  );

  const transcriptContent = transcriptResponse.data.value[0].content;

  // Send to ChatGPT for summarization
  const summary = await axios.post('https://api.makeaihq.com/mcp/chat', {
    messages: [{
      role: 'system',
      content: 'You are a meeting summarization assistant. Extract key decisions, action items, and next steps.'
    }, {
      role: 'user',
      content: `Summarize this meeting transcript:\n\n${transcriptContent}`
    }]
  });

  return summary.data.choices[0].message.content;
}

SharePoint Document Q&A Integration

Enable employees to ask questions about company policies, procedures, and documents stored in SharePoint:

async answerDocumentQuestion(context, question, documentUrl) {
  const accessToken = await this.getUserAccessToken(context);

  // Download document content
  const docResponse = await axios.get(documentUrl, {
    headers: { 'Authorization': `Bearer ${accessToken}` }
  });

  const documentContent = docResponse.data;

  // Query ChatGPT with document context
  const answer = await axios.post('https://api.makeaihq.com/mcp/chat', {
    messages: [{
      role: 'system',
      content: `You are a document Q&A assistant. Answer questions based strictly on the provided document content.`
    }, {
      role: 'user',
      content: `Document content:\n\n${documentContent}\n\nQuestion: ${question}`
    }]
  });

  return answer.data.choices[0].message.content;
}

Multi-Geo Data Residency

For multinational organizations with data sovereignty requirements, deploy bot infrastructure in region-specific Azure data centers:

Azure Bot Service Configuration:

• Create separate bot registrations per region (EU, US, Asia)
• Configure regional messaging endpoints in bot settings
• Use Azure Traffic Manager for geo-routing
• Set dataLocation in Teams manifest to enforce regional routing

Security and Compliance Configuration

Azure AD Conditional Access Policies

Enforce security policies for bot service principal access:

1. Navigate to Azure AD → Security → Conditional Access
2. Create new policy: "ChatGPT Bot Access Policy"
3. Assignments:
   • Users: Select bot service principal
   • Cloud apps: Microsoft Graph
4. Conditions:
   • Locations: Require corporate network or trusted IPs
   • Device platforms: Allow only managed devices
5. Access controls:
   • Grant access with MFA requirement
   • Require compliant device

Data Loss Prevention (DLP) Integration

Prevent sensitive data leakage through bot conversations:

Microsoft Purview DLP Policy:

{
  "name": "ChatGPT Bot DLP Policy",
  "locations": {
    "teamsMessages": true,
    "teamsChatMessages": true
  },
  "rules": [
    {
      "name": "Block Credit Card Numbers",
      "conditions": {
        "contentContainsSensitiveInformation": [
          {
            "sensitiveTypeId": "50842eb7-edc8-4019-85dd-5a5c1f2bb085",
            "minCount": 1,
            "minConfidence": 85
          }
        ]
      },
      "actions": {
        "blockAccess": true,
        "notifyUser": true,
        "notifyAdmin": true
      }
    },
    {
      "name": "Block SSN",
      "conditions": {
        "contentContainsSensitiveInformation": [
          {
            "sensitiveTypeId": "a44669fe-0d48-453d-a9b1-2cc83f2cba77",
            "minCount": 1
          }
        ]
      },
      "actions": {
        "blockAccess": true,
        "quarantine": true
      }
    }
  ]
}

Apply this policy via Microsoft Purview Compliance Portal.

Information Protection Labels

Classify bot conversations with sensitivity labels:

1. Create label: "Internal - ChatGPT Conversations"
2. Configure encryption settings (optional)
3. Apply label automatically to all bot message threads
4. Enable retention policy (e.g., retain for 7 years per compliance requirements)

Compliance Manager Assessment

Track regulatory compliance for your Teams ChatGPT integration:

• SOC 2 Type II: Bot framework audit logs, access controls, encryption in transit/rest
• GDPR: Data subject access requests (DSARs) for bot conversation exports
• HIPAA (if applicable): Business Associate Agreement (BAA) with Azure, encryption, audit trails

Testing and Deployment Strategy

Development Testing with App Studio

1. Install Teams Toolkit in Visual Studio Code
2. Create test tenant with Microsoft 365 Developer Program
3. Sideload app manifest via App Studio:
   • Open Teams → Apps → App Studio
   • Import app package (manifest + icons ZIP)
   • Test in personal scope first
4. Validate bot responses, SSO flow, messaging extensions

Teams App Validator

Before enterprise deployment, validate compliance with Teams app policies:

# Install Teams App Validator CLI
npm install -g @microsoft/teamsfx-cli

# Validate manifest
teamsfx validate --manifest-path ./manifest.json

# Expected output:
# ✓ Manifest schema validation passed
# ✓ Required permissions validated
# ✓ Valid domains verified
# ✓ Icon dimensions correct (32x32, 192x192)

Enterprise App Catalog Deployment

Staged Rollout Strategy:

1. Pilot Group (Week 1): Deploy to IT department (50 users)

   • Monitor for authentication issues, performance, user feedback
   • Gather usage analytics via Application Insights

2. Early Adopters (Week 2-3): Expand to 500 users across departments

   • A/B test messaging extension vs. command-based interactions
   • Optimize response times based on telemetry

3. Global Rollout (Week 4+): Deploy tenant-wide

   • Publish to enterprise app catalog (Teams Admin Center → Manage apps → Upload custom app)
   • Configure app permission policies (allow/block for specific groups)
   • Enable app analytics in Teams Admin Center

Monitoring Post-Deployment:

• Azure Application Insights for bot telemetry
• Teams Admin Center analytics (daily active users, messages sent)
• Microsoft Compliance Center for DLP policy violations

Troubleshooting Common Issues

SSO Authentication Failures

Symptom: OAuth card shown repeatedly despite user granting consent

Root Causes:

• Incorrect webApplicationInfo resource URI in manifest (must be api://botid-YOUR_APP_ID)
• Missing admin consent for delegated permissions
• Token cache expiration without refresh token

Resolution:

// Add token refresh logic
async refreshAccessToken(context) {
  const userData = await this.userDataAccessor.get(context, {});

  if (userData.refreshToken) {
    const tokenResponse = await axios.post(
      `https://login.microsoftonline.com/${process.env.TENANT_ID}/oauth2/v2.0/token`,
      new URLSearchParams({
        client_id: process.env.MICROSOFT_APP_ID,
        client_secret: process.env.MICROSOFT_APP_PASSWORD,
        refresh_token: userData.refreshToken,
        grant_type: 'refresh_token'
      })
    );

    userData.accessToken = tokenResponse.data.access_token;
    userData.refreshToken = tokenResponse.data.refresh_token;
    await this.userDataAccessor.set(context, userData);
  }
}

Graph API Permission Errors

Symptom: 403 Forbidden when calling Microsoft Graph

Root Causes:

• Application permissions not granted admin consent
• User account lacks sufficient privileges (e.g., guest users can't read team info)
• Conditional access policy blocking service principal

Resolution:

1. Verify admin consent: Azure AD → App registrations → API permissions → "Granted for [tenant]" status
2. Test with global admin account first
3. Check Azure AD sign-in logs for blocked requests

Bot Mention Handling Issues

Symptom: Bot doesn't respond when mentioned in channel (@ChatGPT)

Root Cause: Message text includes mention entity, requiring parsing:

this.onMessage(async (context, next) => {
  let userMessage = context.activity.text;

  // Remove bot mention from message text
  if (context.activity.entities) {
    const mentionedBot = context.activity.entities.find(
      entity => entity.type === 'mention' && entity.mentioned.id === context.activity.recipient.id
    );

    if (mentionedBot) {
      userMessage = userMessage.replace(mentionedBot.text, '').trim();
    }
  }

  // Now process cleaned message
  await this.handleChatGPTQuery(context, userMessage);
  await next();
});

Message Delivery Delays

Symptom: Bot responses take 5+ seconds to appear

Root Causes:

• MCP server latency (ChatGPT API slow response)
• Graph API throttling (exceeded rate limits)
• Inefficient conversation state reads/writes

Optimizations:

// 1. Implement response streaming for long ChatGPT responses
async streamChatGPTResponse(context, prompt) {
  const response = await axios.post('https://api.makeaihq.com/mcp/chat/stream', {
    messages: [{ role: 'user', content: prompt }],
    stream: true
  }, { responseType: 'stream' });

  let buffer = '';
  response.data.on('data', async (chunk) => {
    buffer += chunk.toString();

    // Send partial response every 1000 characters
    if (buffer.length > 1000) {
      await context.sendActivity(buffer);
      buffer = '';
    }
  });
}

// 2. Batch Graph API requests
async batchGraphRequests(accessToken, requests) {
  const batchResponse = await axios.post(
    'https://graph.microsoft.com/v1.0/$batch',
    { requests },
    { headers: { 'Authorization': `Bearer ${accessToken}` } }
  );
  return batchResponse.data.responses;
}
