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 Curated account to Claude via Composio Connect, enabling it to add a new link to this week's newsletter, list all publications I can manage, get all subscribers for your main publication, 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 Curated account

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

For example, ask Claude to:

  • "Add a new link to this week's newsletter"
  • "List all publications I can manage"
  • "Get all subscribers for your main publication"

It will prompt you to authenticate and authorize access.

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

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

The Curated MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Curated account. It provides structured and secure access to your newsletters, letting your agent manage publications, curate content, draft issues, and handle subscribers for you.

  • Publication and issue management: Have your agent list all your publications, fetch their issues, and help you stay on top of what's scheduled or published.
  • Draft issue creation: Let your agent create new draft issues for any of your newsletters, making it easy to start new editions with the right content and settings.
  • Curated link collection: Easily add new links, articles, or resources to your publication's collection, so your newsletter always has fresh, relevant content.
  • Subscriber insights: Retrieve lists of all email subscribers for any publication, helping you better understand and engage your audience.
  • Category organization: List and review all categories for your publications, allowing your agent to help you keep content organized and targeted.

Troubleshooting

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

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

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

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

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

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

3. Why does the Curated authorization link not work?

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

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

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

The Curated connection can expire or lose permission.

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

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

Claude can manage the Curated connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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