4. Connect your Netsuite account

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

For example, ask Cowork to:

  • "Generate monthly profit and loss report"
  • "List overdue invoices for all customers"
  • "Create new sales order for a client"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Cowork, and your Netsuite 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 Netsuite through MCP without you sharing account credentials directly with the agent.

What is the Netsuite MCP server, and what's possible with it?

The Netsuite MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Netsuite account. It provides structured and secure access to your business data, so your agent can perform actions like creating invoices, managing inventory, tracking customer records, and automating financial workflows on your behalf.

  • Automated invoice creation and management: Let your agent generate, send, and update invoices for customers, streamlining your accounts receivable process.
  • Real-time inventory control: Ask your agent to check stock levels, update inventory records, and manage supply chain transactions seamlessly.
  • Customer and vendor record management: Have the agent create, update, or retrieve customer and vendor profiles, keeping your CRM data fresh and accurate.
  • Financial reporting and analytics: Direct your agent to pull balance sheets, profit & loss statements, or transaction histories for up-to-date business insights.
  • Order processing automation: Enable your agent to create sales orders, manage purchase orders, and track fulfillment status across your operations.

How to build Netsuite MCP Agent with another framework

FAQ

What are the differences in Tool Router MCP and Netsuite MCP?

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

Can I use Tool Router MCP with Claude Cowork?

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 Netsuite tools.

Can I manage the permissions and scopes for Netsuite while using Tool Router?

Yes, absolutely. You can configure which Netsuite 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.

How safe is my data with Composio Tool Router?

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 Netsuite data and credentials are handled as safely as possible.
