Semrush is a leading SEO and digital marketing platform. The Semrush MCP server lets you analyze domains, research keywords, and audit backlinks using natural language.

What Can It Do?

  • Analyze domains for keywords, traffic, and competitors
  • Research keywords with volume, difficulty, and SERP data
  • Audit backlinks and referring domains
  • Compare competitors by shared or unique keywords

Where to Use It

Add Semrush as a tool to any agent. The agent can then perform SEO research conversationally, choosing the right actions based on context. To add an MCP tool to your agent:
  1. Open your agent’s configuration
  2. Click Add toolsConnect an app with MCP
  3. Search for the integration and select it
  4. Authenticate with your account
You can control which tools your agent has access to. After adding an integration, click on it to enable or disable specific tools based on what your agent needs.

In Workflows (Via Agent Node)

For automated pipelines, use an Agent Node with Semrush tools. This gives you the flexibility of an agent within a deterministic workflow.

As a Custom MCP Node

You can also create a standalone MCP node for a specific action. This generates a reusable node that performs one task, useful when you need the same operation repeatedly in workflows.
To create a custom MCP node:
  1. Go to your node library and search for the integration
  2. Click Create a node with AI
  3. Describe the specific action you want (e.g., “Get domain keywords for hubspot.com”)
  4. Test the node and save it for reuse
Custom MCP nodes are single-purpose by design. For tasks that require multiple steps or dynamic decision-making, use an agent instead.

Troubleshooting

Agents are smart enough to chain multiple API calls together. For example, asking “Analyze competitor.com’s SEO” will gather overview, keywords, and backlinks. If results seem off, check the agent’s step-by-step reasoning.
