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 Linkup account to Claude via Composio Connect, enabling it to find recent articles on quantum computing breakthroughs, summarize top news about generative AI today, get sourced answer about electric vehicle market trends, 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 Linkup account

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

For example, ask Claude to:

  • "Find recent articles on quantum computing breakthroughs"
  • "Summarize top news about generative AI today"
  • "Get sourced answer about electric vehicle market trends"

It will prompt you to authenticate and authorize access.

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

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

The Linkup MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Linkup account. It provides structured and secure access to web search, webpage content, response generation, and account credit information, so your agent can research topics, find relevant sources, retrieve webpage content, generate responses, and check available credits on your behalf.

  • Focused web research: Have your agent search the web for relevant results and insights about a topic, question, company, or recent event.
  • Webpage content retrieval: Direct your agent to fetch a webpage from a given URL and return its content in a readable markdown format.
  • Source-based analysis: Let the agent search for useful sources, retrieve selected pages, and use their content to support further analysis.
  • Response generation: Instruct your agent to generate a response through Linkup using an OpenAI-compatible request.
  • Credit balance checks: Have your agent retrieve your current Linkup credits balance before running more searches or fetching webpages.

Troubleshooting

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

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

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

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

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

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

3. Why does the Linkup authorization link not work?

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

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

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

The Linkup connection can expire or lose permission.

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

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

Claude can manage the Linkup connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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