What authentication does Coupa use?

Coupa supports OAuth 2.0 Client Credentials. You create an OAuth client in Setup > Integrations > OAuth2/OpenID Connect Clients, which generates a Client ID and Client Secret.

Can I create purchase orders through the agent?

Yes. The create_purchase_order tool posts to the /api/purchase_orders endpoint. Provide supplier, ship-to, currency, and line items with quantities and prices.

Does it support invoice matching?

Yes. The query_invoices tool retrieves invoices with their PO match status, tolerance flags, and approval state.

Coupa + Pydantic AI FAQ

Common questions about integrating Coupa MCP Server with Pydantic AI.

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 Coupa MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
