Manage Subscriptions and Accounts for Windsurf

Cascade needs to know which subscriptions are active? Use `list_subscriptions` to pull a complete list of recurring billing plans attached to an account. You can then use `get_metrics` to grab the current MRR, ARR, and TCV numbers in one go. This lets your agent verify if a client's revenue goals are on track before making any changes. It’s perfect for planning multi-step billing reviews.

Process Account Changes with the MCP Server

The `create_account` tool handles setting up new customer billing records based on a JSON object you provide. If an account needs to be shut down, Cascade can run `cancel_subscription`, requiring the subscription ID and effective date. This sequence lets your agent fully manage the lifecycle of a client's financial relationship with Younium.

Retrieve Financial Records for Windsurf

Sometimes you just need to see what happened. Use `list_invoices` to pull every invoice generated by Younium, or use `get_subscription` to get a detailed view of an existing subscription's history and versions. This means your agent can build full audit trails without needing constant human input.
