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 Bouncify account to Claude via Composio Connect, enabling it to verify a new signup email address, check remaining Bouncify verification credits, validate your latest email campaign list, 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 Bouncify account

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

For example, ask Claude to:

  • "Verify a new signup email address"
  • "Check remaining Bouncify verification credits"
  • "Validate your latest email campaign list"

It will prompt you to authenticate and authorize access.

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

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

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

Troubleshooting

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

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

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

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

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

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

3. Why does the Bouncify authorization link not work?

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

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

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

The Bouncify connection can expire or lose permission.

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

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

Claude can manage the Bouncify connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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