How to integrate Nanonets OCR MCP with Codex
Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With Nanonets OCR MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer.
Nanonets OCR is a model-based OCR service for extracting structured data from invoices, receipts, forms, and other documents. It helps turn messy scanned files and PDFs into clean, usable data with trained workflows.
Introduction
Also integrate Nanonets OCR 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 Nanonets OCR 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 Nanonets OCR MCP server, and what's possible with it?
The Nanonets OCR MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Nanonets OCR account. It provides structured and secure access to your OCR models and document extraction results, so your agent can review models, extract fields and tables from public document URLs, find past predictions, and retrieve page or file results on your behalf.
- Document data extraction: Have your agent extract model-defined fields and tables from a publicly reachable document URL.
- OCR model review: Let the agent list your available OCR models and check their readiness, accuracy, extraction fields, and table setup.
- Prediction history lookup: Direct your agent to find document prediction summaries for a model within a chosen date range.
- Complete file results: Instruct your agent to retrieve normalized extraction results for every page of a previously processed document.
- Page-level result review: Have your agent fetch the extracted fields and tables for a specific prediction page.
Conclusion
You've successfully integrated Nanonets OCR with Codex using Composio's MCP server. Now you can interact with Nanonets OCR 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 Nanonets OCR 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 Nanonets OCR operations
- Explore cross-app workflows by connecting more toolkits
- Build automation scripts that leverage Codex's AI capabilities

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.
