Common questions

Is DevX Multichain Balances 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?

The registry does not list a required key, though some servers ask you to sign in on first use.

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 (2.1.0) reached the registry 6 days 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?

DevX Multichain Balances

One call, nine chains. Native coin plus the major tokens for an address on Base, Ethereum, Arbitrum, Optimism, Polygon, Avalanche, BNB Chain, Solana and Tron. It is built for AI agents and apps that need to answer "what does this wallet hold?" without running their own RPC setup.

Everything here is read-only. It never asks for keys and never moves funds.

WhatCost
CLI / stdio MCP devx-multichain-balances (v2)Client for the hosted API below. One chain (native + USDC, USDT on Tron) is free; all / multichain_balances is the paid call, paid from your own wallet keyfree / 0.002 USDC
Remote MCP https://wallet-balances.nextill-pos.workers.dev/mcpbasic_balance (one chain, free) + multichain_balances_infofree
HTTP API GET /v1/balancesUp to 3 addresses (one EVM, one Solana, one Tron) → native + USDC, USDT, DAI, EURC, bridged USDC, WETH, WBTC/cbBTC per EVM chain; SOL + USDC/USDT (SPL); TRX + USDT/USDC (TRC-20); plus up to 10 custom tokens (ERC-20, SPL mint, TRC-20). Block numbers/slots included, stablecoin face-value total0.002 USDC via x402 on Base

CLI

paid, 0.002 USDC per call: every matching chain, all majors, custom tokens

How paying works: the CLI asks the API for its x402 quote, checks that it is USDC on Base, goes to 0xB3cD…f247 and is at or under --max-usd (default 0.01), then signs a gasless EIP-3009 authorization with your key via @x402/fetch. The key stays on your machine. Without a key, all prints the quote, pays nothing and exits with code 2. Since v2.0.0 the package is a thin client. It no longer ships the balance-reading code, and the addresses you query are sent to the hosted API.

MCP

Claude Desktop / Cursor (stdio):

{ "mcpServers": { "multichain-balances": { "command": "npx", "args": ["-y", "devx-multichain-balances", "mcp"], "env": { "X402_PRIVATE_KEY": "0x... (optional, enables the paid tool)" } } } }

Or remote (streamable HTTP): https://wallet-balances.nextill-pos.workers.dev/mcp (free tool + info only)

Tools: basic_balance (free), multichain_balances (0.002 USDC per call, pays only if X402_PRIVATE_KEY is set and never above 0.01 USDC, otherwise returns the quote), multichain_balances_info.

Paid hosted call (x402)

GET https://wallet-balances.nextill-pos.workers.dev/v1/balances?address=0x...,<solana>,<T...>[&chains=base,ethereum,solana,tron][&tokens=base:0xToken,solana:<mint>,tron:<T...>]
  • Answers 402 with an x402 v1 body (X-PAYMENT, network base) and a v2 PAYMENT-REQUIRED header (PAYMENT-SIGNATURE, eip155:8453). Both work. POST with a JSON body works too.
  • 2000 atomic USDC (0.002 USDC) to 0xB3cDDccEe6B150c8efFD55B961afc0Ecefe7f247, settled through the Coinbase CDP facilitator, listed in the CDP x402 Bazaar.
  • Settled only after a result is produced. Bad input, or every chain's RPC failing, is not charged. Failed chains are listed in summary.chains_failed.
  • chains defaults to every chain that matches the addresses you gave (evm = the 7 EVM chains).
Limits
  • It does not discover arbitrary tokens. It checks a fixed, verified list (see /tokens.json), and you can pass extra tokens yourself.
  • On Solana it reads the owner's associated token accounts (where wallets normally keep tokens). Tokens held in other token accounts are not counted.
  • The stablecoin total is face value (1 token = 1 unit), not a market price.
  • Data comes from free public RPC nodes (publicnode.com with fallbacks: mainnet-beta / Tatum gateway for Solana, TronGrid for Tron). Identical calls within 20 s may be served from a short per-instance cache (cache.hit).
