Frequently asked questions
Can I block a fraudulent user through the agent?
Yes! Use the apply_user_decision tool with the user's ID and the appropriate decision ID (like block_user). The action will be applied in Sift immediately.
How do I check the risk score for a specific customer?
Use the get_user_fraud_score tool with the customer's unique ID. Your agent will fetch the latest risk score generated by Sift's machine learning models.
Where do I find my Sift API Key and Account ID?
Log in to your Sift Dashboard and navigate to Settings -> API Keys. You will find your REST API Key and Account ID there.
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 Sift (Chargeback) MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
