Introduction

Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With Procfu MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer.

Also integrate Procfu with

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 Procfu MCP in Codex

Run the setup command

Run this command in your terminal to add the Composio MCP server to Codex.

Terminal

It will initiate the authentication in a browser window, authorize Codex to access your Composio account.

Composio authentication page

(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 composio

Verify the connection

Run codex mcp list to confirm Composio appears as a registered MCP server.

bash
codex mcp list

Codex App

Codex App follows the same approach as VS Code.

  1. Click ⚙️ on the bottom left → MCP Servers → + Add servers → Streamable HTTP:
  2. Fill the header and Key fields with { "x-consumer-api-key" = "ck_*******" }.
  3. The Key is the Composio API key, that you can find on dashboard.composio.dev
  4. Click on Authenticate and authorize Codex to your Composio account and you're all set.
Codex App MCP setup
  1. 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_*******" }

What is the Procfu MCP server, and what's possible with it?

The Procfu MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Procfu account. It provides structured and secure access to advanced Podio automations, letting your agent compare arrays, generate test data, interact with Google Drive and Sheets, and even harness OpenAI for creative tasks—all on your behalf.

  • Automated data comparison and manipulation: Have your agent find differences, additions, deletions, or intersections between two JSON arrays to quickly analyze data changes or synchronize lists.
  • Google Drive file management: Direct your agent to delete files or folders from your Google Drive, streamlining cleanup and organization without manual effort.
  • Dynamic test data and placeholder generation: Instantly generate dummy emails, numbers, images, or addresses for testing, prototyping, or populating demo environments.
  • Retrieve Google Sheets data: Ask your agent to pull contents from a specific Google Sheet as an array, making it easy to process, analyze, or migrate spreadsheet data.
  • Conversational AI and image generation: Let your agent query OpenAI GPT for answers or generate new images from text prompts, extending automation into creative and cognitive tasks.

Supported Tools & Triggers

Tools
Array Difference DeletionsTool to return items removed when comparing two JSON arrays.
Array Diff NewTool to return items added in the second JSON array.
Array Diff SameTool to get items present in both JSON arrays.
Array SortTool to sort a JSON array of values.

Generate Image with OpenAITool to generate an image via OpenAI API.
Get Google Sheet contents as arrayTool to get sheet contents as array.
Get Google Sheets MetadataTool to retrieve metadata of a Google Sheets spreadsheet, including sheet names, IDs, and properties.

Conclusion

You've successfully integrated Procfu with Codex using Composio's MCP server. Now you can interact with Procfu directly from your terminal, VS Code, or the Codex App using natural language commands.

Key benefits of this setup:

  • Seamless integration across CLI, VS Code, and standalone app
  • Natural language commands for Procfu operations
  • Managed authentication through Composio
  • Access to 20,000+ tools across 870+ apps for cross-app workflows
  • CodeAct workbench for complex tool chaining

Next steps:

  • Try asking Codex to perform various Procfu operations
  • Explore cross-app workflows by connecting more toolkits
  • Build automation scripts that leverage Codex's AI capabilities

FAQ

What are the differences in Tool Router MCP and Procfu MCP?

With a standalone Procfu MCP server, the agents and LLMs can only access a fixed set of Procfu tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Procfu 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 Procfu tools.

Can I manage the permissions and scopes for Procfu while using Tool Router?

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