MCP server for three.ws Agent Payment Sessions — govern agent x402 spending without exposing private keys.

Concept

The agent does not hold a wallet. It proposes spend. Governance enforces policy.

A **Payment Session** is a budget envelope you fund once from your three.ws credits. You hand an agent the session bearer token; the agent calls paid x402 endpoints through this server. The platform's wallet signs every transaction. The session's allowlist, per-transaction ceiling, and total budget are enforced atomically on the server — the agent can never overspend.
