If you're running a multi-tenant AI platform and need to track which customer or department ran up your OpenAI or Anthropic bill, this server gives you the plumbing. It exposes `open_ledger`, `record_charge`, and `tenant_chargeback_summary` tools so your agents can log token usage per tenant in real time and generate chargeback reports. The companion repo suggests it pairs with a broader cost tracking stack. Built by MEOK AI Labs with EU AI Act compliance hooks baked in. Useful if you're building internal AI tooling where cost attribution matters more than aggregate spend dashboards can show.
