Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With Agentql MCP integration, you can draft, triage, summarise emails, and much more, 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 870+ 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 Agentql 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.
Verify the connection
Run codex mcp list to confirm Composio appears as a registered MCP server.
Codex 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 connect.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
What is the Agentql MCP server, and what's possible with it?
The Agentql MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Agentql account. It provides structured and secure access to web data and browser automation, so your agent can perform actions like running web queries, extracting structured data, managing remote browser sessions, and tracking usage on your behalf.
- Web page data extraction: Ask your agent to pull specific structured data as JSON from any web page using Agentql queries or natural language prompts.
- Automated browser session management: Let your agent create and control remote browser sessions for complex web automation tasks or interactions that require a live browser.
- Subscription usage monitoring: Have your agent instantly check your current API usage, limits, and billing period to help manage resources and prevent overages.
- Seamless web content querying: Enable your agent to interact with web content directly, searching or extracting information from live web pages in real time.
