ERP connector
NetSuite MCP tools for Claude and ChatGPT, shaped around your subsidiaries and roles.
Oracle ships the NetSuite AI Connector Service and a free set of standard MCP tools. They are generic by design. We build the custom SuiteScript tools and roles that make Claude answer the way your finance and operations teams actually ask.
What your team could ask
- What is open purchase order exposure by subsidiary and vendor, in USD, as of today?
- Which sales orders are pending fulfillment for more than 10 days, and which warehouse holds the stock?
- Run the saved search our AP team uses for unmatched vendor bills and summarize the top issues.
- How does this month's revenue by department compare with budget, using our consolidated view?
What it could do, with approval
Write actions are optional. Each one is shown to a person before it changes anything.
- Create a draft journal entry for an intercompany adjustment, held for approval
- Update a sales order's expected ship date after a person confirms the change
- Raise a vendor record change request instead of editing the vendor directly
What already exists for NetSuite
Checked against vendor and platform sources on October 23, 2026. If an official option covers your need, use it.
Oracle's NetSuite AI Connector Service is an official remote MCP endpoint that Claude and ChatGPT can connect to with OAuth 2.0. Tools come from the free MCP Standard Tools SuiteApp, and developers can add custom tools written in SuiteScript.
- Covers: records, native reports, saved searches, and SuiteQL queries, run with the signed-in user's role.
- Guardrail: the Administrator role cannot be used, and MCP access is off until a role is granted the permission.
- Does not cover: your own business definitions, multi-step workflows, or approval steps. Those need custom tools.
Why build a custom one
Generic tools, specific questions
Standard tools let Claude write its own SuiteQL. Custom tools return the exact figure your team means by 'open exposure' or 'late orders', so answers match the reports finance already trusts.
Roles designed for AI use
We design the non-administrator roles that connect, so each team reaches only the subsidiaries, records, and fields it should.
Writes with a review step
Standard tools can create and update records. We wrap writes in tools that create drafts or require confirmation, so nothing posts unreviewed.
NetSuite plus everything else
When answers need NetSuite and your CRM or warehouse together, a separate MCP server can call both and show where each number came from.
How we would build it
- API
- NetSuite AI Connector Service with custom tools in SuiteScript 2.1, plus SuiteQL and REST web services where needed.
- Sign-in
- OAuth 2.0 with PKCE through the AI Connector Service, signed in as a custom non-administrator role.
Enable the required features in a sandbox and design the roles that will connect.
Build custom SuiteScript tools for the questions your team asks most, read-only first.
Add write tools as draft-and-approve flows, with logging on the integration record.
Test in Claude and ChatGPT, then roll out role by role.
