Automate customer records in Pydantic AI

Stop manual entry for your billing profiles. Use `create_customer` to provision accounts and let your agent handle the payload validation against your Pydantic models. Verify existing account logic with `get_customer`. If you need to clean up your database, `delete_customer` removes records while capturing churn data for your reports.

Track revenue and contracts with this MCP Server

Your agent uses `list_contracts` and `get_contract` to pull active billing rules. It maps these directly to your Python types, ensuring your ARR and MRR metrics stay accurate. Run `create_contract` to bind new subscription terms. The tool handles the heavy lifting, and your agent ensures the response matches your expected schema.

Generate invoices from your Pydantic AI agent

Trigger `create_invoice` to process onboarding fees or subscription renewals. The server performs the plan math, while your agent validates the output to prevent billing errors. Keep tabs on your cash flow using `list_invoices`. Your agent reads the array and flags any discrepancies, giving you a clear view of your revenue without manual spreadsheet work.
