Introduction

Atomic Agent is an open-source AI agent that runs on your machine and supports local models through llama.cpp. Connect it to 1,500+ apps through Composio, including Semrush.

This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a Semrush account. See the Atomic Agent documentation for installation instructions.

How Atomic Agent connects to Semrush

Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication.

Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account.

Connect Semrush to Atomic Agent

  1. Sign up or sign in to the Composio dashboard. Copy your API key.
  2. In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart.
  3. Ask Atomic Agent to do something in Semrush. It searches Composio for the right tool.
  4. On first use, open the sign-in link returned in the chat. Connect your Semrush account, then return to Atomic Agent to continue.

Headless setup

Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file.

bash
COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY

What is the Semrush MCP server, 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 SEO, keyword, backlink, traffic, market, project, and competitive intelligence data, so your agent can research keywords, analyze competitors, inspect backlinks, monitor rankings, and audit sites on your behalf.

  • Keyword and search research: Have your agent find keyword volume, difficulty, CPC, competition, related terms, search questions, SERP results, and advertising history.
  • Competitor and market analysis: Direct your agent to identify organic, paid search, and shopping competitors, compare keyword overlap and backlink profiles, and examine audience overlap.
  • Domain, traffic, and audience insights: Let the agent review domain performance, traffic and engagement trends, acquisition channels, visitor demographics, interests, and geographic distribution.
  • Backlink and ranking analysis: Instruct your agent to inspect backlinks, referring domains, anchor text, Authority Score data, organic rankings, paid search performance, and Google Shopping visibility.
  • Projects and site health monitoring: Have your agent review Semrush projects, check tracked keyword positions over time, and examine site audit health scores, errors, warnings, affected pages, and recommended fixes.

Use Semrush from Atomic Agent

With your account connected, ask Atomic Agent to work with Semrush in natural language. You can connect more apps through the same Composio integration as you need them.

Visit the Atomic Agent website or inspect the Atomic Agent source code.

Troubleshooting

Why is my API key rejected?

Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying.

Why are Composio tools unavailable after saving a key?

Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk.

Does Composio have a free plan?

The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See Composio pricing for the current limits that apply to your connection.

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. Atomic Agent 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.

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