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 1000+ 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 Proxiedmail 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 Proxiedmail MCP server, and what's possible with it?

The Proxiedmail MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Proxiedmail account. It provides structured and secure access to your privacy-focused email services, so your agent can create proxy email addresses, manage bindings, receive emails via webhooks, and update proxy settings automatically.

  • Create unique webhook receivers: Instantly set up custom webhook endpoints for capturing incoming emails through Proxiedmail, making it easy for your agent to receive messages securely.
  • Fetch and manage proxy bindings: Ask your agent to retrieve a list of all your active proxy email bindings, helping you monitor and organize your privacy-layered inboxes.
  • Update proxy binding settings: Let your agent modify existing proxy bindings, such as updating forwarding addresses or tweaking configuration details as your needs change.
  • Seamless API token management: Have your agent securely obtain and refresh Proxiedmail API tokens for seamless, uninterrupted access to your account and services.

Conclusion

You've successfully integrated Proxiedmail with Codex using Composio's MCP server. Now you can interact with Proxiedmail 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 Proxiedmail operations
  • Managed authentication through Composio
  • Access to 20,000+ tools across 1000+ apps for cross-app workflows
  • CodeAct workbench for complex tool chaining

Next steps:

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

FAQ

Frequently asked questions

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

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