## Introduction

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

## Also integrate Kickbox with

## TL;DR

### 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.

## Connect Kickbox to Codex

### How to install Kickbox MCP in Codex
### Run the setup command
Run this command in your terminal to add the Composio MCP server to Codex.

```bash
codex mcp add composio --url https://connect.composio.dev/mcp
```

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

The Kickbox MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Kickbox account. It provides structured and secure access to real-time email verification and quality scoring, so your agent can instantly validate email addresses, reduce bounce rates, and maintain clean contact lists on your behalf.
- Instant single email verification: Ask your agent to check if an email address is valid and deliverable before sending important communications.
- Preventing invalid email submissions: Ensure only legitimate and active emails are accepted into your systems, reducing bounce risk and protecting sender reputation.
- Real-time workflow integration: Validate emails as part of onboarding, registration, or transactional processes to catch errors and typos immediately.
- Email quality scoring: Assess the likelihood of deliverability and filter out risky or low-quality addresses from your lists.
- Automated contact list hygiene: Regularly verify individual emails to keep your CRM and marketing lists accurate and up to date.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `KICKBOX_CHECK_DISPOSABLE` | Check Disposable Email | Tool to check if an email address or domain is from a disposable email service. Use when you need to validate whether an email is temporary or throwaway (e.g., mailinator.com, trashmail.com). This is a free public endpoint that does not require authentication. |
| `KICKBOX_KICKBOX_SINGLE_VERIFICATION_API` | Kickbox Single Verification | Tool to verify a single email address via Kickbox. Use when you need real-time validation of an individual email before critical workflows. |

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Kickbox MCP?

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

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

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