How to integrate AimTell MCP with Codex
Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With AimTell MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer.
AimTell is a web push notification platform for managing websites, subscribers, campaigns, segments, and delivery analytics. Use it to send targeted browser notifications and measure engagement across your web push campaigns.
Introduction

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.

- 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
[mcp_servers.composio]
url = "https://connect.composio.dev/mcp"
http_headers = { "x-consumer-api-key" = "ck_*******" }What is the AimTell MCP server, and what's possible with it?
The AimTell MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your AimTell account. It provides structured and secure access to your websites, subscribers, campaigns, segments, notifications, and delivery analytics, so your agent can manage audiences, prepare campaigns, send push notifications, review results, and track delivery activity on your behalf.
- Website and subscriber insights: Have your agent list your AimTell websites, browse subscribers, review their attributes and notification history, and filter audiences by segment.
- Audience segment management: Let the agent create, update, list, or delete audience segments used to organize subscribers and target campaigns.
- Campaign draft management: Direct your agent to create and revise manual campaign drafts, review campaigns across supported campaign types, or delete drafts you no longer need.
- Targeted push notifications: Instruct your agent to send a one-off push notification to selected subscribers, a segment, an alias, or your website's full reachable audience.
- Delivery and campaign reporting: Have your agent track daily metrics, review campaign sends, deliveries, bounces, clicks, conversions, and revenue where available, or inspect recent notification logs.

Karan skipped his own birthday party to fix our critical issue. It was 10pm and he diverted his Waymo to help us instead. This really sets the bar — it shows the commitment you need when users rely on your software.
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.
With hands-on help from their founder, we integrated Gmail and Google Drive in just 30 minutes. This level of personal support and commitment is exactly what startups should strive for.
