Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With Big data cloud 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 Big data cloud 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 Big data cloud MCP server, and what's possible with it?
The Big data cloud MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Big data cloud account. It provides structured and secure access to advanced geolocation, reverse geocoding, ASN analysis, and data validation APIs, so your agent can perform actions like looking up IP details, verifying emails, assessing network risk, and analyzing BGP routing on your behalf.
- IP geolocation and country insights: Let your agent instantly geolocate any IP address, retrieve country-level demographics, and pull rich metadata about locations worldwide.
- Reverse geocoding with timezone detection: Have your agent translate GPS coordinates into precise locality information along with accurate timezone data—all in one go.
- Email address verification and data hygiene: Ensure your agent can validate email addresses for proper syntax, domain legitimacy, and disposability to help maintain clean and reliable datasets.
- ASN and BGP analytics: Allow your agent to analyze internet routing by fetching ranked lists of autonomous systems, upstream and downstream provider details, and active BGP prefixes for a given ASN.
- Cybersecurity hazard assessment: Empower your agent to fetch and interpret hazard reports for IP addresses, identifying threats like VPN/proxy usage, blacklist status, and hosting risks.

FAQ
What are the differences in Tool Router MCP and Big data cloud MCP?
With a standalone Big data cloud MCP server, the agents and LLMs can only access a fixed set of Big data cloud tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Big data cloud and many other apps based on the task at hand, all through a single MCP endpoint.
Can I use Tool Router MCP with Codex?
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 Big data cloud tools.
Can I manage the permissions and scopes for Big data cloud while using Tool Router?
Yes, absolutely. You can configure which Big data cloud 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.
How safe is my data with Composio Tool Router?
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 Big data cloud data and credentials are handled as safely as possible.
