Cascade chains legal invoice approvals via MCP Server

Cascade uses `list_invoices` to pull your active queue and traces the entire authorization path without waiting for your go-ahead. It queries `get_invoice_approval_workflow` to map out who needs to sign off next, presenting you with a clear timeline of pending actions. Executing `approve_invoice` or `reject_invoice` directly from your chat buffer handles the back-office paperwork instantly. This lets Cascade update your team on Slack or log the action without you having to context-switch into a separate billing portal.

Deep-dive into legal matters and tags

Tracking complex litigation or patent filings gets easy when Cascade links code repositories to active cases using `list_matters`. The agent automatically retrieves metadata using `get_matter_header` to keep your project files aligned with legal counsel's records. The agent checks current taxonomies with `list_matter_tags` and appends the right identifiers using `tag_matter` to keep your legal spend organized by sprint.

Instant connectivity checks

Cascade runs `get_account_check` first to verify your Apperio connection before attempting any complex workflows. If the connection is broken, Windsurf alerts you immediately so you can fix your credentials before running billing pipelines. Once verified, the agent safely pulls granular billing data using `get_invoice_details`. This ensures your financial reports contain accurate, live data every time.
