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 Semrush account to Claude via Composio Connect, enabling it to list top keywords for your domain, analyze backlinks for competitor example.com, fetch weekly traffic trends for site, 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 Semrush account

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

For example, ask Claude to:

  • "List top keywords for your domain"
  • "Analyze backlinks for competitor example.com"
  • "Fetch weekly traffic trends for site"

It will prompt you to authenticate and authorize access.

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

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

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

Troubleshooting

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

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

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

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

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

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

3. Why does the Semrush authorization link not work?

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

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

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

The Semrush connection can expire or lose permission.

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

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

Claude can manage the Semrush connection for you.

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

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

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

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

FAQ

Frequently asked questions

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