Creates governed x402 payment sessions with a budget, endpoint allowlist, and per-transaction caps so an agent can pay any x402 endpoint without holding a raw key.

About

three.ws Agent Payments is an MCP server that lets an agent pay any x402 endpoint through governed payment sessions: you create a session with a budget, an endpoint allowlist, and per-transaction caps, then the agent spends against a session bearer token (pss_...) instead of a raw key. Payments settle on-chain. A solo builder reaches for it to give an agent bounded, auditable spending power for machine-to-machine payments.
