Zixflow is an AI-powered CRM and messaging platform for SMS, Email, and WhatsApp. It unifies outreach and automation so you never miss an important lead or message.

7 Tools

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 Zixflow account to Claude via Composio Connect, enabling it to send a bulk SMS campaign to all new leads, add a follow-up reminder for every hot lead, list conversations from WhatsApp with unread responses, 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.

bash
https://connect.composio.dev/mcp
Add custom connector dialog with Composio MCP server URL

3. Authorize in your browser

4. Connect your Zixflow account

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

For example, ask Claude to:

  • "Send a bulk SMS campaign to all new leads."
  • "Add a follow-up reminder for every hot lead."
  • "List conversations from WhatsApp with unread responses."

It will prompt you to authenticate and authorize access.

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

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

The Zixflow MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Zixflow account. It provides structured and secure access so your agent can perform Zixflow operations on your behalf.

Troubleshooting

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

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

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

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

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

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

3. Why does the Zixflow authorization link not work?

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

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

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

The Zixflow connection can expire or lose permission.

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

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

Claude can manage the Zixflow connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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