## Introduction

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

## 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 Mailcoach to Codex

### How to install Mailcoach 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 Mailcoach MCP server, and what's possible with it?

The Mailcoach MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Mailcoach account. It provides structured and secure access to your email marketing platform, so your agent can manage campaigns, organize subscriber lists, create templates, and automate email workflows on your behalf.
- Email campaign creation and scheduling: Direct your agent to launch new campaigns, send emails to specific lists, or set up campaign schedules based on your marketing needs.
- Subscriber list and segmentation management: Let your agent create new email lists, add or confirm subscribers, and apply tags for better audience segmentation and targeting.
- Template management and customization: Instruct your agent to create, update, or organize reusable email templates and transactional templates for efficient campaign building.
- Automated suppression and bounce handling: Have your agent add suppressions for bounced or blocked addresses, keeping your lists clean and compliant with deliverability best practices.
- Bulk subscriber import and data enrichment: Enable your agent to import subscribers via CSV, append new data to existing imports, and streamline growth of your contact lists.

## Supported Tools

|---|---|---|
| `MAILCOACH_ADD_CAMPAIGN` | Add Mailcoach Campaign | Tool to create a new Mailcoach campaign. Use when you need to send or schedule an email campaign to a specific list or segment. |
| `MAILCOACH_ADD_EMAIL_LIST` | Add Email List | Tool to create a new email list. Use when you need to manage and organize subscribers before sending campaigns. Use after authentication. |
| `MAILCOACH_ADD_SUPPRESSION` | Add suppression | Tool to add a suppression entry. Use after detecting a bounce, spam complaint, or manual block. |
| `MAILCOACH_ADD_TAG` | Add Tag to Email List | Tool to create a new tag within a specific email list. Use after confirming the email list exists. |
| `MAILCOACH_ADD_TAGS_TO_SUBSCRIBER` | Add Tags to Subscriber | Add tags to a subscriber for segmentation and targeting. Tags are appended to existing tags. Use after obtaining a subscriber UUID from listing subscribers or creating a new subscription. |
| `MAILCOACH_ADD_TRANSACTIONAL_EMAIL_TEMPLATE` | Add Transactional Email Template | Creates a new email template in Mailcoach via POST /api/templates. Use this action to create reusable HTML templates that can be referenced when sending transactional emails. Returns the created template with its UUID, which can be used to reference, update, or delete the template later. |
| `MAILCOACH_APPEND_TO_SUBSCRIBER_IMPORT` | Append to Subscriber Import | Tool to append CSV data to an existing subscriber import. Use after retrieving a subscriber import when additional subscriber data needs to be added. |
| `MAILCOACH_CONFIRM_SUBSCRIBER` | Confirm Subscriber | Confirm a subscriber's subscription to an email list (double opt-in confirmation). Use this action to finalize a subscriber's subscription after they have been added to an email list with confirmation required. This is typically called after the subscriber clicks a confirmation link in their email. Prerequisites: - A subscriber must exist (created via MAILCOACH_SUBSCRIBE_TO_EMAIL_LIST action) - The subscriber must be in 'unconfirmed' status (skip_confirmation was false or not set) Returns 204 No Content on success. If the subscriber is already confirmed or does not exist, appropriate error messages are returned. |
| `MAILCOACH_CREATE_SEGMENT` | Create Segment for Email List | Tool to create a new segment within an email list. Use when you need to target specific groups of subscribers based on tags. |
| `MAILCOACH_CREATE_SUBSCRIBER_IMPORT` | Create Subscriber Import | Creates a new subscriber import in Mailcoach. Use this to bulk import subscribers from CSV data into an email list. The import is created in 'draft' status and must be started separately using the start_subscriber_import action. The CSV must include a header row with at least an 'email' column. Optional columns include 'first_name', 'last_name', 'tags', and custom attributes. Requires a valid email_list_uuid from an existing email list. |
| `MAILCOACH_DELETE_CAMPAIGN` | Delete Campaign | Tool to delete a campaign by UUID. Use when you need to permanently remove a campaign after confirming its identifier. |
| `MAILCOACH_DELETE_EMAIL_LIST` | Delete Email List | Tool to delete an email list by UUID. Use when you need to permanently remove an email list after confirming its identifier. |

| `MAILCOACH_DELETE_SUBSCRIBER` | Delete Subscriber | Permanently delete a subscriber by UUID from Mailcoach. Use this tool when you need to completely remove a subscriber and all their data. After deletion, the email address can be re-subscribed in the future. This action is irreversible - consider using unsubscribe instead if you want to preserve subscriber history. |
| `MAILCOACH_DELETE_SUBSCRIBER_IMPORT` | Delete Subscriber Import | Tool to delete a subscriber import by its UUID. Use when you need to permanently remove a subscriber import after confirming its identifier. |
| `MAILCOACH_DELETE_SUPPRESSION` | Delete Suppression | Tool to delete a suppression entry by UUID. Use when you need to permanently remove a suppression after confirming its identifier. |

## Frequently Asked Questions

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

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

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

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