Full read-write Claude connector for SAP
Have Claude create purchase orders and post entries in SAP
Stop hopping between transaction codes to look up records and key in documents. Claude pulls the data, drafts the purchase order, sales order, or journal entry against the right vendor and accounts, and posts only once you approve.
SAP is the ERP backbone that large companies run finance, procurement, supply chain, and operations on, spanning S/4HANA and older ECC systems. People want Claude to do more than look up records: to create and update business documents like purchase orders, sales orders, and journal entries directly inside SAP.
What is a SAP MCP server?
A SAP MCP server is a small hosted service that exposes SAP's data and actions to Claude over the Model Context Protocol, so Claude can inventory, orders, and operations inside your own account. We build it as a custom connector with separate read and write tools, and destructive actions stay gated behind your approval.
What can SAP's current connector do today?
Today, there is no first-party Claude or MCP connector for SAP, and the platform's scale, on-premise deployments, and firewalled landscapes make access nontrivial. Teams that wire something up usually start read-leaning, pulling reports or record details. Creating or posting transactional documents needs a purpose-built connector with scoped API or RFC access and human-in-the-loop controls.
What does full read-write SAP access unlock?
Full read-write SAP access lets Claude create a purchase order, update a sales order, post a journal entry, release a blocked invoice, or check stock and propose a goods movement, then commit once you approve. The lookups and data entry that used to mean switching between transaction codes happen in one place, with an approval step before anything posts.
- Create or update a purchase order against the right vendor and cost center
- Create or change a sales order and confirm pricing and delivery dates
- Post a journal entry to the correct accounts after you review it
- Release a blocked invoice or purchase requisition once approved
- Look up stock levels and propose a goods movement or transfer posting
- Update master data fields on a customer, vendor, or material record
Can Claude create a purchase order in SAP?
Yes. With a custom read-write connector, Claude can create a purchase order in SAP through its API layer, mapping the values to the right vendor and cost center. It can also change an existing order. Because posting commits a document, that step is gated behind your approval before anything is released.
Can Claude post a journal entry in SAP?
Claude can post a journal entry in SAP, mapping the lines to the correct accounts after you review them. It can also release a blocked invoice or purchase requisition. These write actions run through scoped API or RFC access, and the posting itself only happens once you confirm it.
Will the SAP connector have more access than my own account?
No. The connector authenticates with credentials scoped to the authorizations the work needs and never exceeds what your own SAP user can do. Read tools and write tools stay separate, and create, change, and post actions are gated behind your approval, so it inherits your permissions rather than expanding them.
How a SAP connector works
We build a small MCP server that connects to SAP through its API layer (OData, BAPI, or RFC) with OAuth or scoped service credentials, using the narrowest authorizations the work needs. Read tools (look up records, run reports) and write tools (create, change, post) are separated, and posting or releasing documents requires your confirmation. For on-premise landscapes we add firewall and IP allowlisting so traffic stays inside your network, and Claude only ever has the access your own SAP user already has.
