Mandat — an agent you

Mandat — an agent you can hand a budget to

We delegate to people we trust with a mission, a budget and a few rules. Assistants still wait for us at every payment. With Mandat you sign one mandate; the agent plans, negotiates, books and pays inside it.

What I built • A PayPal mandate, three autonomy levels, daily and monthly limits, and a Stop switch • Money rules enforced in code: each deposit is checked against the budget before PayPal is called • Deposits held, not charged: captured on confirmation, voided or refunded when plans change • One product, three integrations: a PayPal web app, an NVIDIA Nemotron version and an Alexa+ add-on

Result • Real PayPal sandbox payments (Vault, Orders, Payments, Agent Toolkit); no real money moves • Nemotron on Nebius Token Factory: a filmed run with 6 deposits held, then captured • Alexa+: MCP server on AWS Lambda, MCP Apps cards, OAuth 2.1 account linking, 3 languages, 144 automated tests • Open source (MIT)
