Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Sendbird account to Claude via Composio Connect, enabling it to add users to a group chat channel, ban a disruptive user from group chat, get unread message count for a user, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

3. Connect your Sendbird account

Back in Claude, ask it to connect to Sendbird or give it any Sendbird-related task.

For example, ask Claude to:

  • "Add users to a group chat channel"
  • "Ban a disruptive user from group chat"
  • "Get unread message count for a user"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Sendbird account is ready to use.

What is the Sendbird Claude Connector, and what's possible with it?

The Sendbird MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Sendbird account. It provides structured and secure access to your in-app chat, voice, and video features, so your agent can perform actions like creating group channels, managing users, moderating conversations, and tracking unread message counts on your behalf.

  • Group channel management: Let your agent create new group channels, add or ban members, and delete channels as needed to keep conversations organized and secure.
  • User account administration: Automatically register new users or remove users from your Sendbird application, simplifying user lifecycle management.
  • Message moderation and cleanup: Empower your agent to delete specific messages—helping enforce community guidelines and remove unwanted content instantly.
  • Unread count and status tracking: Retrieve up-to-date counts of unread messages, mentions, and channel invitations for any user to surface important conversations.
  • Channel preference insights: Access and update user count preferences in group channels, tailoring notification and message delivery based on user needs.

Troubleshooting

1. Why does Claude not use the Composio connector for Sendbird?

The connector can show as connected, but Claude must use it in each Sendbird conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Sendbird again.

2. Why does Claude show an MCP server error before Sendbird connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Sendbird.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Sendbird.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Sendbird authorization link not work?

The Composio connector is one server. Your Sendbird account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Sendbird connection.
  • Composio creates a fresh Sendbird authorization link.
  • Open that link in your browser and finish the Sendbird sign-in.

4. Why do Sendbird actions fail after they worked before?

The Sendbird connection can expire or lose permission.

  • Ask Claude to inspect the Sendbird connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Sendbird account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Sendbird.
  • If the action still fails with a permission error, check that the connected account has that permission in Sendbird itself.

5. How do I switch to a different Sendbird account?

Claude can manage the Sendbird connection for you.

  • Ask Claude to disconnect or delete the current Sendbird account.
  • Ask Claude to connect Sendbird again.
  • Open the new Composio authorization link for Sendbird.
  • Sign in with the other Sendbird account in the browser.
  • After the account connects, ask Claude to retry the Sendbird task.

6. Why is my Sendbird connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Sendbird connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Sendbird tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Sendbird.

FAQ

Frequently asked questions

With a standalone Sendbird MCP server, the agents and LLMs can only access a fixed set of Sendbird tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Sendbird and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Sendbird tools.

Yes, absolutely. You can configure which Sendbird scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Sendbird data and credentials are handled as safely as possible.
