Common questions

Is AgentPay safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: AGENT_PRIVATE_KEY

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.3) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

AgentPay MCP Server

Agent-to-Agent micropayments via x402 + MCP — let AI agents autonomously pay for API access with USDC on Base.

Install

Option A — Remote MCP（推荐，无需本地安装）

在 Cursor / Claude / 任意支持 Streamable HTTP 的客户端添加：

https://agentpay-xhs-production.up.railway.app/mcp

官方 Registry 条目：io.github.yyxqqq777/agentpay

Option B — 本地 stdio（`uvx` / PyPI）

"mcpServers": { "agentpay": { "command": "uvx", "args": ["mcp-server-agentpay"], "env": { "AGENT_PRIVATE_KEY": "0xYourAgentPrivateKey" } } } }

只需填付款钱包私钥（需有 USDC）。网关地址已内置，一般不用改。

或永久安装：

pip install mcp-server-agentpay

or

uv tool install mcp-server-agentpay

Tools

Tool	Description	Cost
`xhs_get_note_detail`	Xiaohongshu note detail	0.01 USDC/call
`xhs_get_user_notes`	Xiaohongshu user posted notes list	0.01 USDC/call
`china_wholesale_pricing_query`	Factory-direct wholesale pricing (1688/Yiwu)	0.01 USDC/call
`agentpay_payment_status`	View payment config, wallet, and spending limits	Free

Example prompts

"帮我看看这条小红书笔记写了什么：https://www.xiaohongshu.com/explore/..."
"拉一下这个博主最近发的笔记，user_id=..."
"Search wholesale prices for wireless earbuds under $3"
"What's my AgentPay wallet and spending limit?"

Environment Variables

Variable	Required	Description
`AGENT_PRIVATE_KEY`	Yes（付费工具）	付款钱包私钥
`MAX_SPEND_PER_CALL`	No	单次上限（默认 `0.10`）
`GATEWAY_BASE_URL`	No	网关地址（默认已指向公网 Gateway）

How it works

MCP Client  →  mcp-server-agentpay  →  x402 Gateway  →  Paid API

(auto 402 → sign → retry) (verify USDC)

Tool call hits a paid API endpoint
Gateway returns 402 Payment Required with USDC payment details
MCP server signs payment and retries automatically
JSON data flows back to the LLM

Self-host the Gateway

If you operate the paid API, deploy the gateway separately:

pip install "mcp-server-agentpay[gateway]"

.env: PAYMENT_MODE=production + upstream keys + your receive wallet

agentpay-gateway

Real USDC settlement (x402)

Mode	Behavior
`PAYMENT_MODE=demo`	Local fake pay (dev only)
`PAYMENT_MODE=production`	Official Facilitator verify + settle on-chain

Testnet (Base Sepolia) — use https://x402.org/facilitator, network eip155:84532.

# Fund a test agent with Sepolia USDC, then:

PYTHONPATH=src python scripts/test_x402_settlement.py

Mainnet — set PAYMENT_NETWORK=eip155:8453 and a mainnet facilitator (https://api.cdp.coinbase.com/platform/v2/x402 or PayAI). USDC goes to WALLET_RECIPIENT_ADDRESS.

See .env.example.

This package is designed for the official MCP Registry.

# 1. Publish to PyPI

pip install build twine python -m build && twine upload dist/*

2. Publish to MCP Registry (packages + remotes)

./scripts/publish_all.sh
