How to integrate Apiverve MCP with Codex
Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With Apiverve MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer.
Apiverve delivers a suite of powerful APIs that simplify integration for developers. It's designed for reliability and scalability so you can build faster, smarter applications without the integration headache.
Introduction
Also integrate Apiverve with
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 Apiverve 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.
codex mcp login composioVerify the connection
Run codex mcp list to confirm Composio appears as a registered MCP server.
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
[mcp_servers.composio]
url = "https://connect.composio.dev/mcp"
http_headers = { "x-consumer-api-key" = "ck_*******" }What is the Apiverve MCP server, and what's possible with it?
The Apiverve MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Apiverve account. It provides structured and secure access to a broad suite of APIs, so your agent can perform actions like fetching real-time air quality, converting currencies, retrieving app data, calculating ages, and delivering word definitions or antonyms on your behalf.
- Real-time air quality reporting: Instantly get air quality data, including AQI, pollutant levels, and health recommendations for any city.
- Currency conversion automation: Effortlessly convert between currencies using up-to-date exchange rates, perfect for financial tasks and travel planning.
- App Store metadata retrieval: Fetch detailed information about apps from the app store, including ratings and descriptions, by supplying app IDs and country codes.
- Word definitions and antonyms: Ask your agent to define any word or find its opposites, supporting smarter text analysis and content creation.
- Travel and information utilities: Calculate age from a date of birth, get the distance between airports, or retrieve detailed airline and airport info—all with a simple prompt.
Conclusion
You've successfully integrated Apiverve with Codex using Composio's MCP server. Now you can interact with Apiverve 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 Apiverve 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 Apiverve operations
- Explore cross-app workflows by connecting more toolkits
- Build automation scripts that leverage Codex's AI capabilities
Supported Tools
Every Apiverve action and event your agent gets out of the box.

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.
