Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With the Ahrefs MCP integration, Codex can analyze backlinks and referring domains, research keywords and search volume, track domain rating, find organic competitors, and check top pages, all without leaving the terminal or the app, whichever you prefer.

Why use Composio?
Apart from a managed and hosted MCP server, you will get:
- CodeAct: A dedicated workbench that allows GPT to write its code to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling.
- Large tool responses: Handle them to minimise context rot.
- Dynamic just-in-time access to 20,000 tools across 1700+ other Apps for cross-app workflows. It loads the tools you need, so GPTs aren't overwhelmed by tools you don't need.
How to install Ahrefs MCP in Codex
Run the setup command
Run this command in your terminal to add the Composio MCP server to Codex.
It will initiate the authentication in a browser window, authorize Codex to access your Composio account.
(Optional) Authenticate with OAuth
To authenticate manually, run the login command to open a browser window and authorize Codex to access your Composio account.
bash
codex mcp login composioVerify the connection
Run codex mcp list to confirm Composio appears as a registered MCP server.
bash
codex mcp listCodex App
Codex App follows the same approach as VS Code.
- Click ⚙️ on the bottom left → MCP Servers → + Add servers → Streamable HTTP:
- Fill the header and Key fields with
{ "x-consumer-api-key" = "ck_*******" }. - The Key is the Composio API key, that you can find on dashboard.composio.dev
- Click on Authenticate and authorize Codex to your Composio account and you're all set.
- Restart and verify if it's there in
.codex/config.toml
bash
[mcp_servers.composio]
url = "https://connect.composio.dev/mcp"
http_headers = { "x-consumer-api-key" = "ck_*******" }Try it
Ask Codex for a Ahrefs task. The first time, Composio asks you to connect your Ahrefs account.
For example, ask it to:
- "Get domain rating trend for competitor site"
- "List all broken backlinks for your website"
- "Find keyword volume for 'AI tools' in US"
What is the Ahrefs MCP server, and what's possible with it?
The Ahrefs MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Ahrefs account. It provides structured and secure access to backlink, keyword, competitor, ranking, and search results data, so your agent can analyze backlinks, compare competitors, review keyword rankings, inspect search results, and discover keyword ideas on your behalf.
- Backlink and anchor analysis: Have your agent retrieve backlinks, summarize backlink statistics, and examine the anchor text pointing to a website or URL.
- Competitor research: Let the agent compare competitors based on keyword rankings and organic search performance.
- Keyword ranking history: Direct your agent to review current rank tracking data and historical keyword performance for a website or domain.
- Search results and keyword ideas: Instruct your agent to inspect search results for chosen queries and find related search suggestions for a keyword or phrase.
- Outgoing links and crawler verification: Have your agent review outgoing link statistics for a website or retrieve AhrefsBot IP ranges for crawler verification.
Conclusion
You've successfully integrated Ahrefs with Codex using Composio's MCP server. Now you can interact with Ahrefs directly from your terminal, VS Code, or the Codex App using natural language commands.
Key benefits of this setup:

FAQ
Frequently asked questions
With a standalone Ahrefs MCP server, the agents and LLMs can only access a fixed set of Ahrefs tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Ahrefs and many other apps based on the task at hand, all through a single MCP endpoint.
Yes, you can. Codex 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 Ahrefs tools.
Yes, absolutely. You can configure which Ahrefs 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 Ahrefs data and credentials are handled as safely as possible.
