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 Moonclerk 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 Moonclerk MCP server, and what's possible with it?
The Moonclerk MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Moonclerk account. It provides structured and secure access to your Moonclerk data, so your agent can perform actions like listing customers, tracking payments, reviewing subscriptions, and analyzing discounts on your behalf.
- Comprehensive customer listing: Retrieve and filter your Moonclerk customer records, making it easy to access up-to-date client data and plan details.
- Detailed payment tracking: Ask your agent to list all payments or filter them by form, customer, time frame, or payment status—perfect for quick financial overviews.
- Subscription management and review: Effortlessly get a full rundown of all active, paused, or cancelled subscriptions associated with your business.
- Payment form overview: Have your agent fetch a complete list of your payment forms, helping you audit, review, or analyze available checkout options in seconds.
- Discount analytics: Instantly pull details on all discounts applied to customers, so you can monitor promotional effectiveness and customer engagement.
Conclusion
You've successfully integrated Moonclerk with Codex using Composio's MCP server. Now you can interact with Moonclerk 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 Moonclerk operations
- Managed authentication through Composio
- Access to 20,000+ tools across 1000+ apps for cross-app workflows

FAQ
Frequently asked questions
With a standalone Moonclerk MCP server, the agents and LLMs can only access a fixed set of Moonclerk tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Moonclerk 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 Moonclerk tools.
Yes, absolutely. You can configure which Moonclerk 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 Moonclerk data and credentials are handled as safely as possible.

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.
Abhi Arya
Co-founder, Opennote
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.
