How to integrate Dynosend MCP with Codex
Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With Dynosend MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer.
Api Key
Dynosend is an email marketing platform for audiences, contacts, campaigns, transactional messages, and customer events. Use it to manage lifecycle email, track engagement, and keep customer communication organized.

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 Dynosend 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.
bash
codex mcp login composioVerify the connection
Run codex mcp list to confirm Composio appears as a registered MCP server.
bash
codex mcp listCodex 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 dashboard.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
bash
[mcp_servers.composio]
url = "https://connect.composio.dev/mcp"
http_headers = { "x-consumer-api-key" = "ck_*******" }What is the Dynosend MCP server, and what's possible with it?
The Dynosend MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Dynosend account. It provides structured and secure access to your audiences, contacts, campaigns, transactional messages, and customer events, so your agent can manage contacts, operate campaigns, send transactional messages, track customer activity, and maintain your blacklist on your behalf.
- Audience and contact management: Have your agent list audiences, create or update contacts, manage tags and custom fields, find duplicate contacts, and delete contacts when required for privacy compliance.
- Subscription and blacklist control: Let the agent subscribe or unsubscribe contacts, check whether an email is blacklisted, and add addresses to the blacklist when needed.
- Campaign operations and insights: Direct your agent to list campaigns, review delivery and engagement results, start ready campaigns, or pause and resume campaign delivery.
- Transactional email delivery: Instruct your agent to send configured transactional messages through your Dynosend account.
- Customer event tracking: Have your agent record application events for contacts to keep customer activity available in Dynosend.
Conclusion
You've successfully integrated Dynosend with Codex using Composio's MCP server. Now you can interact with Dynosend 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 Dynosend 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 Dynosend 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 Dynosend MCP server, the agents and LLMs can only access a fixed set of Dynosend tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Dynosend 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 Dynosend tools.
Yes, absolutely. You can configure which Dynosend 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 Dynosend data and credentials are handled as safely as possible.

A lot of students tell us that the moment their connected tools start talking to each other inside Opennote feels almost magical. The agent just knows them, and it's immensely helped keep new users on the platform.

We chose Composio over Pipedream because it delivered depth where it mattered — niche tools and tricky edge cases other platforms simply ignored. That gave us confidence to scale without compromising.

As a solo builder, shipping fast is life or death. The only way I can outcompete incumbents is by outmanoeuvring them. Getting bogged down managing agent auth would have been a death sentence.

Before Composio, adding tool integrations was slow and resource-intensive. Each one could take weeks of engineering time, and maintaining them meant constantly keeping up with API changes.
