Frequently asked questions
What authentication does SAP S/4HANA require?
SAP S/4HANA uses Communication Arrangements with a dedicated Communication User. You create a technical user in the Fiori Launchpad, assign it to a Communication System, and link it to the appropriate Communication Scenario (e.g. SAP_COM_0008 for Business Partners).
Can I create purchase orders through the agent?
Yes. The create_purchase_order tool posts to the A_PurchaseOrder OData endpoint. Provide the supplier, purchasing organization, plant, material, quantity, and price — the agent returns the PO number on success.
Does it support querying custom OData services?
Absolutely. The query_odata tool executes GET requests against any OData v4 service exposed via your Communication Arrangement, including custom CDS views. Full $filter, $expand, and $select support is included.
Can I check stock levels across multiple plants?
Yes. The get_material_stock tool queries the A_MaterialStock OData service, returning current stock quantities by plant and storage location. You can filter by material number, plant, or storage location.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your SAP S/4HANA MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
