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 Amcards account to Claude via Composio Connect, enabling it to list all cards I've sent this month, find contacts with the last name Smith, show newest contacts added last week, 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 Amcards account

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

For example, ask Claude to:

  • "List all cards I've sent this month"
  • "Find contacts with the last name Smith"
  • "Show newest contacts added last week"

It will prompt you to authenticate and authorize access.

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

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

The Amcards MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Amcards account. It provides structured and secure access to your card library and contact list, so your agent can retrieve cards, manage contacts, monitor campaigns, and streamline customer engagement on your behalf.

  • Card library management: Instantly retrieve a list of all greeting cards in your Amcards account so you can review, organize, or select cards for campaigns.
  • Comprehensive contact retrieval: Ask your agent to fetch your contact list—including names, emails, and details—making it easy to personalize outreach or update records.
  • Filtered contact lookup: Find specific contacts by searching with filters like last name, first name, or email, allowing you to target the right recipients quickly.
  • Campaign preparation and monitoring: Let your agent pull card and contact data to support mailing campaigns, track card activity, and optimize your customer connection strategy.

Troubleshooting

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

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

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

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

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

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

3. Why does the Amcards authorization link not work?

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

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

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

The Amcards connection can expire or lose permission.

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

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

Claude can manage the Amcards connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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