An agent's account economics — plan quotas, metered usage, invoices, receipts, and earnings.
npx @getmcp/cli add io.github.nirholas/billing-mcpRequires Node.js 18+. Community-contributed server. Review source before installing.
THREE_WS_SESSIONYour three.ws session token (the value of the `__Host-sid` cookie from a signed-in browser). REQUIRED — it exposes private billing data, so every account-scoped read (get_billing_summary, query_usage, export_billing_history, get_receipt, get_revenue) resolves the calling user from it and returns only your data. Only the public get_fee_info works without it. Treat like a password.
