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 to your SEO, keyword, and advertising analytics, so your agent can perform actions like keyword research, competitor analysis, backlink audits, and ad copy retrieval automatically on your behalf.

  • Comprehensive keyword research and reporting: Let your agent fetch broad match keywords, generate batch keyword overviews, and analyze key SEO metrics like search volume and difficulty in real time.
  • Competitor and backlink analysis: Ask your agent to pull backlink profiles, perform batch comparisons of domains, and summarize backlink authority and link types for competitive intelligence.
  • Ad campaign and copy insights: Have the agent retrieve unique Google Ads copies for any domain, helping you benchmark and optimize your own ad strategies based on real competitor data.
  • Content and category profiling: Enable your agent to analyze and categorize domains or URLs, surfacing topic strengths and audience focus areas for smarter content planning.
  • Anchor text and authority monitoring: Direct your agent to report on anchor text distributions and authority score profiles, giving you actionable insights for improving link-building efforts.

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.
