Add Microsoft Teams Channel

Connect NanoClaw to Microsoft Teams for interactive chat in team channels, group chats, and direct messages.

Install

NanoClaw doesn't ship channels in trunk. This skill copies the Teams adapter in from the channels branch.

Pre-flight (idempotent)

Skip to Credentials if all of these are already in place:

• src/channels/teams.ts exists
• src/channels/teams-registration.test.ts exists
• src/channels/index.ts contains import './teams.js';
• @chat-adapter/teams is listed in package.json dependencies

Otherwise continue. Every step below is safe to re-run.

1. Fetch the channels branch

git fetch origin channels

2. Copy the adapter and its registration test

git show origin/channels:src/channels/teams.ts                 > src/channels/teams.ts
git show origin/channels:src/channels/teams-registration.test.ts > src/channels/teams-registration.test.ts

3. Append the self-registration import

Append to src/channels/index.ts (skip if the line is already present):

import './teams.js';

4. Install the adapter package (pinned)

pnpm install @chat-adapter/[email protected]

5. Build and validate

pnpm run build
pnpm exec vitest run src/channels/teams-registration.test.ts

Both must be clean before proceeding. teams-registration.test.ts is the one integration test: it imports the real channel barrel and asserts the registry contains teams. It goes red if the import './teams.js'; line is deleted or drifts, if the barrel fails to evaluate, or if @chat-adapter/teams isn't installed (the import throws) — so it also implicitly verifies the dependency from step 4. The adapter also calls core's createChatSdkBridge(...); that typed core-API consumption is guarded by pnpm run build.

End-to-end message delivery against a real Teams workspace is verified manually once the service is running — see Next Steps and the webhook setup above.

Credentials

Two paths — manual (Azure Portal) or auto (Teams CLI).

Auto: Teams CLI

Requires Node.js 18+, a Microsoft 365 account with sideloading permissions, and a public HTTPS endpoint (ngrok, Cloudflare Tunnel, or similar).

1. Install the CLI:

   npm install -g @microsoft/teams.cli@preview

1. Sign in and verify:

   teams login
   teams status

1. Create the Entra app, client secret, and bot registration:

   teams app create \
     --name "NanoClaw" \
     --endpoint "https://your-domain/api/webhooks/teams"

The CLI prints the credentials as CLIENT_ID, CLIENT_SECRET, and TENANT_ID. Map them to NanoClaw's env keys:

• CLIENT_ID → TEAMS_APP_ID
• CLIENT_SECRET → TEAMS_APP_PASSWORD
• TENANT_ID → TEAMS_APP_TENANT_ID

1. Pick Install in Teams from the post-create menu and confirm in the Teams dialog.

Continue to Configure environment.

The steps below describe the manual Azure Portal path.

Step 1: Create an Azure AD App Registration

1. Go to Azure Portal > App registrations > New registration
2. Name it (e.g., "NanoClaw")
3. Supported account types: Single tenant (your org only) or Multi tenant (any org)
4. Click Register
5. Copy the Application (client) ID and Directory (tenant) ID from the Overview page

Step 2: Create a Client Secret

1. In the App Registration, go to Certificates & secrets
2. Click New client secret, description "nanoclaw", expiry 180 days
3. Click Add and copy the Value immediately (shown only once)

Step 3: Create an Azure Bot

1. Go to Azure Portal > search Azure Bot > Create
2. Fill in:

• Bot handle: unique name (e.g., "nanoclaw-bot")
• Type of App: match your app registration (Single or Multi Tenant)
• Creation type: Use existing app registration
• App ID: paste from Step 1
• App tenant ID: paste from Step 1 (Single Tenant only)

1. Click Review + create > Create

Or use Azure CLI:

az group create --name nanoclaw-rg --location eastus
az bot create \
  --resource-group nanoclaw-rg \
  --name nanoclaw-bot \
  --app-type SingleTenant \
  --appid YOUR_APP_ID \
  --tenant-id YOUR_TENANT_ID \
  --endpoint "https://your-domain/api/webhooks/teams"

Step 4: Configure Messaging Endpoint

1. Go to your Azure Bot resource > Configuration
2. Set Messaging endpoint to https://your-domain/api/webhooks/teams
3. Click Apply

Step 5: Enable Teams Channel

1. In the Azure Bot resource, go to Channels
2. Click Microsoft Teams > Accept terms > Apply

Or via CLI:

az bot msteams create --resource-group nanoclaw-rg --name nanoclaw-bot

Step 6: Create and Sideload Teams App

Create a manifest.json:

{
  "$schema": "https://developer.microsoft.com/en-us/json-schemas/teams/v1.16/MicrosoftTeams.schema.json",
  "manifestVersion": "1.16",
  "version": "1.0.0",
  "id": "YOUR_APP_ID",
  "packageName": "com.nanoclaw.bot",
  "developer": {
    "name": "NanoClaw",
    "websiteUrl": "https://your-domain",
    "privacyUrl": "https://your-domain",
    "termsOfUseUrl": "https://your-domain"
  },
  "name": { "short": "NanoClaw", "full": "NanoClaw Assistant" },
  "description": {
    "short": "NanoClaw assistant bot",
    "full": "NanoClaw personal assistant powered by Claude."
  },
  "icons": { "outline": "outline.png", "color": "color.png" },
  "accentColor": "#4A90D9",
  "bots": [{
    "botId": "YOUR_APP_ID",
    "scopes": ["personal", "team", "groupchat"],
    "supportsFiles": false,
    "isNotificationOnly": false
  }],
  "permissions": ["identity", "messageTeamMembers"],
  "validDomains": ["your-domain"]
}

Create two icon PNGs (32x32 outline.png, 192x192 color.png), zip all three files together.

Sideload in Teams:

1. Open Teams > Apps > Manage your apps
2. Click Upload an app > Upload a custom app
3. Select the zip file

Sideloading requires Teams admin access. Free personal Teams does NOT support sideloading. Use a Microsoft 365 Business account or developer tenant.

Step 7: Receive All Messages (Optional)

By default, the bot only receives messages when @-mentioned. To receive all messages in a channel without @-mention, add RSC permissions to manifest.json:

{
  "authorization": {
    "permissions": {
      "resourceSpecific": [
        { "name": "ChannelMessage.Read.Group", "type": "Application" }
      ]
    }
  }
}

Configure environment

Add to .env:

TEAMS_APP_ID=your-app-id
TEAMS_APP_PASSWORD=your-client-secret
# For Single Tenant only:
TEAMS_APP_TENANT_ID=your-tenant-id
TEAMS_APP_TYPE=SingleTenant

Sync to container: mkdir -p data/env && cp .env data/env/env

Webhook server

The Chat SDK bridge automatically starts a shared webhook server on port 3000 (configurable via WEBHOOK_PORT env var). The server handles /api/webhooks/teams for Teams and other webhook-based adapters. This port must be publicly reachable from the internet for Azure Bot Service to deliver activities.

For local development without a public URL, use a tunnel (e.g., ngrok http 3000) and update the messaging endpoint in Azure Bot Configuration.

Next Steps

If you're in the middle of /setup, return to the setup flow now.

Otherwise, run /manage-channels to wire this channel to an agent group.

Channel Info

• type: teams
• terminology: Teams has "teams" containing "channels." The bot can also receive DMs (personal scope) and group chat messages. Channels support threaded replies.
• platform-id-format: teams:{base64-encoded-conversation-id}:{base64-encoded-service-url} — auto-generated by the adapter, not human-readable. Use the auto-created messaging group ID for wiring.
• how-to-find-id: Send a message to the bot in the channel. NanoClaw auto-creates a messaging group and logs the platform ID. Use that messaging group ID for wiring.
• supports-threads: yes (channels only; DMs and group chats are flat)
• typical-use: Team collaboration with the bot in channels; personal assistant via DMs
• default-isolation: Separate agent group per team. DMs can share an agent group with your main channel for unified personal memory.
