Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With Faceup 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 Faceup 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 Faceup MCP server, and what's possible with it?
The Faceup MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Faceup account. It provides structured and secure access to your organization's Faceup reporting data, so your agent can perform actions like retrieving anonymous report statistics, filtering metrics by key attributes, and generating compliance summaries on your behalf.
- Retrieve organization-wide reporting statistics: Instantly access high-level metrics on anonymous reports submitted by employees or students in your organization.
- Filter report metrics by date range: Ask your agent to pull report counts or trends for any custom period—daily, weekly, monthly, or across semesters and fiscal years.
- Break down data by location or department: Let your agent segment statistics by school, office, or group to help pinpoint where issues are being reported.
- Monitor compliance and engagement trends: Use your agent to track changes in reporting volume, detect spikes in activity, and support proactive response and compliance efforts.
- Automate reporting for audits and reviews: Have your agent generate tailored statistics for compliance checks or leadership briefings, saving time and reducing manual effort.

FAQ
What are the differences in Tool Router MCP and Faceup MCP?
With a standalone Faceup MCP server, the agents and LLMs can only access a fixed set of Faceup tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Faceup 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 Faceup tools.
Can I manage the permissions and scopes for Faceup while using Tool Router?
Yes, absolutely. You can configure which Faceup 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 Faceup data and credentials are handled as safely as possible.
