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 Mocean account to Claude via Composio Connect, enabling it to send SMS alert to a customer, deliver two-factor authentication code via SMS, initiate voice call verification for user sign-up, 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 Mocean account

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

For example, ask Claude to:

  • "Send SMS alert to a customer"
  • "Deliver two-factor authentication code via SMS"
  • "Initiate voice call verification for user sign-up"

It will prompt you to authenticate and authorize access.

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

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

The Mocean MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Mocean account. It provides structured and secure access to your messaging and verification tools, so your agent can send SMS messages, initiate voice calls, manage two-factor authentication flows, and engage customers with real-time notifications on your behalf.

  • Automated SMS delivery: Instantly send text messages to users for alerts, notifications, or customer engagement with just a prompt to your agent.
  • Voice call automation: Instruct your agent to place voice calls for reminders, confirmations, or interactive customer communication flows.
  • Multi-factor authentication (MFA): Let your agent handle one-time password (OTP) generation and verification, streamlining secure user onboarding and login.
  • Two-way messaging management: Enable your agent to receive and process incoming SMS messages, supporting interactive conversations and quick customer responses.
  • Bulk campaign execution: Run large-scale SMS or voice campaigns through your agent, reaching many users simultaneously for marketing or transactional updates.

Troubleshooting

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

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

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

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

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

  • 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 Mocean.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Mocean authorization link not work?

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

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

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

The Mocean connection can expire or lose permission.

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

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

Claude can manage the Mocean connection for you.

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

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

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

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Mocean 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 Mocean.

FAQ

Frequently asked questions

With a standalone Mocean MCP server, the agents and LLMs can only access a fixed set of Mocean tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Mocean 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 Mocean tools.

Yes, absolutely. You can configure which Mocean 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 Mocean data and credentials are handled as safely as possible.
