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.

Sift (Chargeback) + AutoGen FAQ

Common questions about integrating Sift (Chargeback) MCP Server with AutoGen.

How does AutoGen connect to MCP servers?

Create an MCP tool adapter and assign it to one or more agents in the group chat. AutoGen agents can then call Sift (Chargeback) tools during their conversation turns.

Can different agents have different MCP tool access?

Yes. AutoGen's role-based architecture lets you assign specific MCP tools to specific agents, so a querying agent has different capabilities than a reviewing agent.
