FAQ

Frequently asked questions

01

Can I manually start a retention flow for a customer via AI?

Yes! Use the start_flow tool and provide the Flow ID, Customer ID, and Subscription ID. This will initialize the retention experience for that user immediately.

02

How do I see if a customer successfully stayed after a flow?

Run the get_flow_session query with the specific Session ID. It will return the outcome and status of the retention attempt.

03

Is it possible to update a subscription's status via AI?

Absolutely. Use the update_subscription tool by providing the Subscription ID and the new status to synchronize data between your systems and Upzelo.

04

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.

05

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.

06

Can I switch LLM providers without changing MCP code?

Absolutely. Pydantic AI abstracts the model layer. your Upzelo MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
