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 Memberstack account to Claude via Composio Connect, enabling it to add a new member with email and plan, list all members who joined this month, update a member's email address, 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.

Add to Claude

Add manually

In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.

2. Authorize in your browser

Click Connect. You'll be redirected to a browser window where you can authorize Composio to continue.

3. Connect your Memberstack account

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

For example, ask Claude to:

  • "Add a new member with email and plan"
  • "List all members who joined this month"
  • "Update a member's email address"

It will prompt you to authenticate and authorize access.

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

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

The Memberstack MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Memberstack account. It provides structured and secure access to your member management system, so your agent can perform actions like creating members, updating profiles, managing plans, and retrieving membership data on your behalf.

  • Automated member creation and onboarding: Instantly add new users to your platform with customizable fields, plans, and metadata—no manual input needed.
  • Profile updates and member management: Let your agent update member details, modify custom fields, or change emails and metadata as your users grow or their needs change.
  • Membership plan handling: Effortlessly list available plans, assign plans to members, or remove free plans when subscriptions change.
  • Member lookup and insights: Retrieve individual member profiles by ID or email, or fetch a paginated list of all your members for deeper analysis and automation.
  • Secure member deletion: Ensure compliance and data hygiene by directing your agent to safely delete members who no longer require access.

Troubleshooting

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

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

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

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

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

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

3. Why does the Memberstack authorization link not work?

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

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

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

The Memberstack connection can expire or lose permission.

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

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

Claude can manage the Memberstack connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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