Can I see the most common reason users are trying to cancel?

Yes! Use the `get_session_aggregates` tool. The agent will return grouped data showing which reasons are being selected most frequently in your cancellation flows.

How do I update the billing contact for a customer whose payment failed?

Use the `update_billing_contacts` tool. Provide the customer ID and the new contact details. This ensures Churnkey sends dunning and recovery emails to the right person.

Where do I find my Churnkey Data API Key and App ID?

Log in to your Churnkey dashboard and navigate to **Settings > Account**. You can find your App ID and generate a Data API Key in the API section.

Churnkey + VS Code Copilot FAQ

Common questions about integrating Churnkey MCP Server with VS Code Copilot.

Which VS Code version supports MCP?

MCP support requires VS Code 1.99 or later with the GitHub Copilot extension. Ensure both are updated to the latest version. Older versions of Copilot may not expose the Agent mode toggle.

How do I switch to Agent mode?

Open the Copilot Chat panel and look for two mode options: "Ask" and "Agent". Click "Agent" to enable autonomous tool calling. In Ask mode, Copilot provides conversational answers but cannot invoke MCP tools.

Can I restrict which MCP tools Copilot can access?

Yes. VS Code shows a tool consent dialog before any MCP tool is invoked for the first time. You can also configure tool access policies at the organization level through GitHub Copilot settings.

Does MCP work in VS Code Remote or Codespaces?

Yes. MCP servers configured via .vscode/mcp.json work in Remote SSH, WSL, and GitHub Codespaces environments. The MCP connection is established from the remote host, so ensure the server URL is accessible from that environment.
