About three.ws Agent Payments
three.ws Agent Payments is an MCP server published by the GitHub account nirholas. Governed x402 payment sessions: pay any endpoint with budget, allowlist & per-tx caps, no key.
It runs on your own machine: your AI client starts it from the npm package @three-ws/agentcore-payments-mcp at version 0.1.5.
It asks for 2 secrets: THREE_WS_SESSION and PAYMENT_SESSION_TOKEN. Give it a key with the least access that still works.
Version 0.1.5 was published on 10 October 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 0 warn, 0 fail, 2 info. How we check.
What it asks for
| Variable | Required | Secret | Description |
|---|---|---|---|
THREE_WS_SESSION | No | Yes | Your three.ws session token (value of the `__Host-sid` cookie from a signed-in browser). Required for account management operations: create_payment_session, list_payment_sessions, check_payment_session, cancel_payment_session. |
PAYMENT_SESSION_TOKEN | No | Yes | A payment session bearer token (starts with 'pss_') from create_payment_session. Used by the agent for pay_with_session calls when no inline token is passed. Treat like a spending card — it authorizes payments up to the session's budget. |
THREE_WS_BASE | No | No | Base URL of the three.ws API. Override only when self-hosting or targeting a preview deployment. |
THREE_WS_TIMEOUT_MS | No | No | Per-request HTTP timeout in milliseconds. x402 payments involve on-chain settlement so this should be generous (default: 30000). |
