How to connect Nanonets OCR to Claude Cowork

Cowork is Anthropic's AI agent for knowledge work. Think of it as Claude Code for everything else. It works autonomously with your computer, local files, and applications to accomplish complex tasks. This guide walks you through the easiest and most secure way to connect your Nanonets OCR account to Cowork via Composio Connect, enabling it to extract invoice totals from uploaded PDFs, read purchase orders into structured fields, convert scanned receipts to expense data, and more such actions on your behalf without compromising your account security.

4. Connect your Nanonets OCR account

Back in Cowork, ask the agent to connect to Nanonets OCR or give it any Nanonets OCR-related task.

For example, ask Cowork to:

  • "Extract invoice totals from uploaded PDFs"
  • "Read purchase orders into structured fields"
  • "Convert scanned receipts to expense data"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Cowork, and your Nanonets OCR account is ready to use.

What is Claude Cowork?

Claude Cowork is Anthropic's agent for general knowledge work. It can use your computer, files, and connected applications to complete longer-running tasks across your work tools.

With Composio Connect, Cowork can securely access apps like Nanonets OCR through MCP without you sharing account credentials directly with the agent.

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.

FAQ

Frequently asked questions

With a standalone Nanonets OCR MCP server, the agents and LLMs can only access a fixed set of Nanonets OCR tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Nanonets OCR and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork 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 Nanonets OCR tools.

Yes, absolutely. You can configure which Nanonets OCR 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 Nanonets OCR data and credentials are handled as safely as possible.
