Perplexity

Terminal-Driven Client Onboarding

`create_client` registers a new customer account directly from your command line. When you pipe a CSV of new signups into Claude Code, the agent parses the rows and executes this tool for each contact. There is no web interface to load and no manual forms to fill out. This MCP Server makes mass onboarding fast and scriptable for DevOps teams. You can run `get_client` to inspect specific balances and contact fields. To verify the imports, the agent calls `list_clients` to display the newly created profiles in your terminal.

CLI-Based Invoice Operations

`create_invoice` generates a new billing record directly from your terminal session. Claude Code triggers this tool at the end of a deployment script or a cron job to bill clients for server usage. It formats the payload and sends it to the API instantly. This integrates your billing straight into your shell pipelines using the MCP Server. If you need to send a draft or change a status, the agent uses `update_invoice` to modify the record. It also executes `get_invoice` to output the current PDF link or payment status directly to your stdout.

Headless Ledger Cleanup via MCP Server

`delete_invoice` removes canceled or duplicate bills from your system without leaving your SSH session. When a billing run fails or needs a reset, Claude Code identifies the bad records and purges them. The agent handles the cleanup in seconds, keeping your accounting ledger accurate. For complete database hygiene, the agent uses `delete_client` to remove inactive or test accounts. You can chain these commands in your shell scripts to automate monthly database maintenance. This headless approach saves time and keeps your production data pristine.
