远程 MCP 端点,让助手查询加密钱包持仓——Base 与以太坊上的 ETH、ERC-20 代币及美元价值,每次调用以 USDC 付费

可以做什么
读取完整钱包投资组合:指定地址与链(默认 Base)的原生 ETH 余额、ERC-20 代币列表(含符号、余额、美元价值、合约地址)以及总美元价值。
适用场景
适用于助手在兑换或交易前确认钱包余额、跟踪投资组合或报告余额。轻量余额工具适合只需快速查看 ETH 与 USDC 的场景。不涵盖 gas 价格、兑换报价或收益机会。不涵盖 gas 价格、兑换报价或收益机会。不涵盖 gas 价格、兑换报价或收益机会。不涵盖 gas 价格、兑换报价或收益机会。不涵盖 gas 价格、兑换报价或收益机会。不涵盖 gas 价格、兑换报价或收益机会。不涵盖 gas 价格、兑换报价或收益机会。不涵盖 gas 价格、兑换报价或收益机会。不涵盖 gas 价格、兑换报价或收益机会。不涵盖 gas 价格、兑换报价或收益机会。不涵盖 gas 价格、兑换报价或收益机会。不涵盖 gas 价格、兑换报价或收益机会。不涵盖 gas 价格、兑换报价或收益机会。不涵盖 gas 价格、兑换报价或收益机会。不涵盖 gas 价格、兑换报价或收益机会。不涵盖 gas 价格、兑换报价或收益机会。不涵盖 gas 价格、兑换报价或收益机会。不涵盖 gas 价格、兑换报价或收益机会。不涵盖 gas 价格、兑换报价或收益机会。不涵盖 gas 价格、兑换报价或收益机会。不涵盖 gas 价格、兑换报价或收益机
运行要求
远程 SSE 端点;无需本地运行时、账户或 API 密钥。需要支持 x402 的客户端和 Base L2 上有 USDC 余额的钱包来支付每次调用,并需能访问服务商的网络。
安装前请注意
每次调用都需付费:投资组合工具 0.008 美元,余额工具 0.003 美元,通过 x402 以 Base L2 上的 USDC 结算,助手可能在无需注册或 API 密钥的情况下花费真实资金。客户端必须能签署 402 支付挑战,因此涉及有余额的钱包。查询的钱包地址会发送给第三方服务。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Wallet Portfolio Tracker API,将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Web executable,通过 SSE。 远程服务在工作区中配置后即可从网页运行时运行。

交给智能体安装

把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体,或 SourceWeft 对话中。智能体会读取该服务器的安装指南,先向你展示发布者、端点和登录方式,经你同意后再把它添加到你的客户端。密钥不会写进任何命令。

阅读 https://sourceweft.com/mcp/io.github.Br0ski777%2Fwallet-portfolio/install.md,并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前,先告诉我它的发布者、端点和登录方式,等我确认。不要把 API 密钥写进命令或我会提交的文件;问我密钥应从哪里获取。

README

Wallet Portfolio Tracker API

[MCP Server] [x402] [License: MIT]

Full crypto wallet holdings across chains -- ETH, ERC-20 tokens, USD values. Portfolio tracking for agents. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.

Part of the klymax402 marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.

Quickstart -- MCP

Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):

json
{  "mcpServers": {    "wallet-portfolio": {      "url": "https://wallet-portfolio.api.klymax402.com/mcp"    }  }}

Quickstart -- HTTP (x402)

bash
curl "https://wallet-portfolio.api.klymax402.com/api/portfolio?address=0x0000000000000000000000000000000000dEaD"# -> 402 Payment Required, with an x402 payment challenge in the response body

Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.

Tools

ToolMethodPathPriceDescription
wallet_get_portfolioGET/api/portfolio$0.008Get full portfolio with all token balances and USD values

wallet_get_balancePOST/api/balance$0.003Get ETH and USDC balance only (POST variant)

wallet_get_portfolio

Use this when you need to check a crypto wallet's holdings across chains. Returns a full portfolio breakdown in JSON.

Parameters

NameTypeRequiredDescription
addressstringyesWallet address (0x...)
chainstringnoBlockchain network (default: base)

Returns

  • nativeBalance -- ETH balance with USD value
  • tokens -- array of ERC-20 tokens with symbol, balance, USD value, contract address
  • totalValueUsd -- aggregate portfolio value in USD
  • chain -- which network was queried

Example response:

json
{"nativeBalance":{"symbol":"ETH","balance":"1.234","valueUsd":3827.50},"tokens":[{"symbol":"USDC","balance":"500.00","valueUsd":500.00}],"totalValueUsd":4327.50,"chain":"base"}

When to use: executing a swap to verify the wallet has sufficient balance. Essential for portfolio tracking, balance checks, and agent self-reporting.

Not for: gas prices (use gas_get_current_price), swap quotes (use dex_get_swap_quote), yield opportunities (use defi_find_best_yields).

wallet_get_balance

Use this when you need a quick check of a wallet's ETH and USDC balance only. Returns a lightweight JSON response -- cheaper than full portfolio.

Parameters

NameTypeRequiredDescription
addressstringyesWallet address (0x...)
chainstringnoBlockchain network (default: base)

Returns

  • ethBalance -- native ETH balance with USD value
  • usdcBalance -- USDC balance with USD value
