How do I find my Highnote API Key?

Log in to your Highnote dashboard, navigate to **Settings > API**, and you will be able to generate and copy your API key. Make sure to distinguish between Test and Live keys based on your environment.

What environments are supported?

The integration supports both the **Test** (Sandbox) and **Live** (Production) environments. You must specify which one you are connecting to during setup to ensure the correct API endpoints are used.

Can I freeze a card through this integration?

Yes! Use the `update_card_status` tool and set the status to `FROZEN`. This will immediately prevent any new authorizations on that card. You can set it back to `ACTIVE` to unfreeze it.

Is the integration secure for financial data?

Absolutely. The integration uses industry-standard Basic Authentication over HTTPS. Your credentials and financial data are encrypted and stored securely within the Vinkius Cloud infrastructure.

Highnote + AutoGen FAQ

Common questions about integrating Highnote 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 Highnote 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.
