How do you connect Claude to SEMrush?

Quick Answer: You can connect Claude to SEMrush using the SEMrush MCP (Model Context Protocol) server, which gives Claude direct access to live SEMrush data including domain overviews, keyword gap analysis, and backlink pulls. Setup takes under 10 minutes and requires a SEMrush API key plus Claude Pro or Claude Desktop.

Copying SEMrush data into Claude manually is one of the biggest time drains in B2B SaaS SEO workflows. You export a CSV, paste it in, lose context, and repeat the cycle for every new query. The SEMrush MCP server eliminates that entirely.

This guide walks you through connecting Claude to SEMrush step by step, then shows you exactly how to use that connection for the three research tasks that matter most to SaaS teams: domain overviews, keyword gap analysis, and backlink pulls. If you are building a broader SEO system around these workflows, it can also help to benchmark against some of the best B2B SaaS SEO agencies and understand how they structure research and execution.

What Is the SEMrush MCP and Why Does It Matter?

MCP stands for Model Context Protocol. It is an open standard that lets AI tools like Claude connect directly to external data sources and APIs without you manually passing data back and forth.

The SEMrush MCP server acts as a bridge between Claude and the SEMrush API. Once connected, Claude can query live SEMrush data mid-conversation, process it, and return structured analysis, all without you leaving the chat window.

For B2B SaaS teams running competitive research, this changes the workflow significantly. Instead of exporting five reports and stitching them together in a spreadsheet, you ask Claude a question and it pulls the data, interprets it, and surfaces the insight in one step.

What You Need Before You Start

Before setting up the connection, confirm you have the following:

• A SEMrush account with API access. The SEMrush API is available on Guru and Business plans. You will need your API key from the SEMrush account settings.
• Claude Pro or Claude Desktop. Custom connectors and MCP integrations require Claude Pro at minimum. Claude Desktop (the downloadable app) is the recommended environment for MCP setups.
• Node.js installed on your machine. The MCP server runs locally and requires Node.js version 18 or higher.

If you are running Claude through the web interface only, you will need to upgrade to Claude Pro or download Claude Desktop before proceeding.

How to Connect Claude to SEMrush: Step-by-Step

Step 1: Get Your SEMrush API Key

1. Log in to your SEMrush account
2. Navigate to Account Settings then API Units
3. Copy your API key and keep it somewhere accessible

Your API key authenticates every request Claude makes to SEMrush, so treat it like a password.

Step 2: Install the SEMrush MCP Server

Open your terminal and run the following command:

npx @semrush/mcp-server

This installs the SEMrush MCP server package locally. You only need to do this once.

Step 3: Configure Claude Desktop to Use the MCP Server

1. Open Claude Desktop
2. Go to Settings then Developer then Edit Config
3. This opens your claude_desktop_config.json file
4. Add the following block inside the mcpServers object:

{
  "mcpServers": {
    "semrush": {
      "command": "npx",
      "args": ["-y", "@semrush/mcp-server"],
      "env": {
        "SEMRUSH_API_KEY": "your_api_key_here"
      }
    }
  }
}

5. Replace your_api_key_here with the API key you copied in Step 1
6. Save the file

Step 4: Restart Claude Desktop

Close Claude Desktop completely and reopen it. After restart, you should see the SEMrush server listed as an active tool in the bottom of the chat interface. A small hammer icon or tool indicator confirms the MCP connection is live.

Step 5: Test the Connection

Type the following prompt into Claude:

"Use SEMrush to pull a domain overview for [yourdomain.com]"

If the connection is working, Claude will query SEMrush in real time and return organic traffic estimates, keyword counts, authority score, and backlink totals for that domain.

How to Use Claude and SEMrush for B2B SaaS Research

Once the connection is live, the real value comes from knowing which prompts to run. Here are the three most useful workflows for SaaS SEO teams.

Domain Overview: Benchmark a Competitor in Seconds

A domain overview gives you a snapshot of a competitor's organic footprint. With the MCP connected, you can pull this and ask Claude to interpret it in the context of your own positioning.

Prompt to use:

"Pull a SEMrush domain overview for [competitor.com] and summarise their top traffic-driving pages, estimated monthly organic visits, and authority score. Flag any categories where they appear to have strong topical coverage."

Claude will return the raw data from SEMrush and layer on interpretation. You are not just getting numbers, you are getting a read on where the competitor is winning and why.

What to look for in the output:

• Authority score above 50 signals an established domain that will be hard to displace on head terms
• Top pages with high traffic but low keyword counts often indicate strong brand or navigational intent
• Categories with dense keyword coverage show where they have invested in content depth

Keyword Gap Analysis: Find the Opportunities Your Competitors Own

Keyword gap analysis compares your domain against one or more competitors and identifies keywords they rank for that you do not. This is one of the highest-ROI research tasks in SaaS SEO because it surfaces demand that already exists.

Prompt to use:

"Run a keyword gap analysis between [yourdomain.com] and [competitor1.com] and [competitor2.com] using SEMrush. Show me the top 20 keywords where both competitors rank in the top 10 but we do not appear. Group them by intent if possible."

Claude will pull the gap data from SEMrush, filter it, and organise the results by search intent (informational, commercial, transactional). This saves roughly 30 minutes of manual filtering that you would otherwise do in the SEMrush interface. Teams trying to operationalise this across content, SEO, and demand gen can pair it with a strong B2B SaaS marketing operations framework so insights actually turn into execution.

How to act on the output:

• Keywords with commercial or transactional intent that you are missing are the highest priority
• If two or more competitors rank for the same keyword in the top 5, that signals a well-established SERP you need a strong content angle to enter
• Use the grouped output to brief content directly, the intent clustering tells you what format each piece needs

If your team needs outside support turning keyword opportunities into assets, reviewing some of the best B2B SaaS content marketing agencies can be a useful next step.

Backlink Pulls: Identify Link Sources Worth Targeting

Backlink research through Claude and SEMrush lets you pull a competitor's link profile and immediately ask strategic questions about it, without switching between tabs or exporting data.

Prompt to use:

"Pull the top 50 referring domains linking to [competitor.com] using SEMrush. Filter for domains with an authority score above 40 and identify any that appear to be industry publications, directories, or resource pages we could also target."

Claude cross-references the SEMrush backlink data against the domain types and surfaces the most actionable link targets. What would take 20 minutes of manual triage in a spreadsheet takes under 2 minutes with this prompt.

What to do with the output:

• Industry publications that link to competitors are the first outreach targets
• Resource pages and directories often have submission processes, add these to a link building queue
• If multiple competitors share the same referring domain, that source clearly covers your category and is worth prioritising

Common Setup Issues and How to Fix Them

Claude is not showing the SEMrush tool after restart Check that your JSON config file has no syntax errors. A missing comma or bracket will silently break the config. Use a JSON validator before saving.

API key errors on first query Confirm your SEMrush plan includes API access. Starter and Pro plans do not include API units by default. You may need to purchase API units separately even on a Guru plan.

Slow response times on large queries The SEMrush API has rate limits. If you are pulling large keyword gap reports, break the query into smaller segments (for example, one competitor at a time) to avoid timeouts.

MCP server not found error Make sure Node.js 18 or higher is installed. Run node --version in your terminal to check. If you are on an older version, update Node.js first.

Is Claude the Right Tool for SEMrush Research?

Claude is particularly well-suited to SEMrush research workflows because of how it handles large data sets within a conversation. Unlike tools that summarise data in isolation, Claude maintains context across a full research session, so you can pull a domain overview, run a keyword gap, and then ask follow-up questions that reference both data sets at once.

For B2B SaaS teams doing competitive research, content briefing, or link building, this means fewer context switches and faster time from raw data to a decision.

FAQs

What is the SEMrush MCP server? The SEMrush MCP server is a locally-run connector that links Claude to the SEMrush API using the Model Context Protocol standard. Once configured, it allows Claude to query live SEMrush data including domain metrics, keyword data, and backlink information directly inside a conversation, without manual data exports.

Do I need a paid SEMrush plan to connect it to Claude? Yes. SEMrush API access is available on Guru and Business plans. You also need sufficient API units in your account. Standard Pro plans do not include API access by default, so check your plan tier before setting up the MCP connection.

Can I use the SEMrush MCP with Claude on the web? The MCP setup described here works with Claude Desktop (the downloadable app). Claude Pro users on the web interface can create custom connectors, but the MCP server configuration requires the desktop app for the most straightforward setup.

How is this different from copying SEMrush data into Claude manually? Manual data pasting loses context between sessions and requires you to re-export every time the data changes. The MCP connection gives Claude access to live SEMrush data on demand, so your research reflects current rankings, not a snapshot from last week.

What SEMrush data can Claude access through the MCP? Through the SEMrush MCP, Claude can access domain overviews, organic keyword data, keyword gap analysis, backlink profiles, referring domain data, and keyword research tools. The exact tools available depend on your SEMrush plan and the API units available in your account.
