Common questions

Is MGO — Multi-chain Gas Optimizer 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: MGO_PRIVATE_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.2.0) reached the registry 18 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

chain-ops-mgo

Multi-chain Gas Optimizer — Compare real-time gas prices across 9 EVM chains and get the cheapest-chain recommendation. Pay-per-call via x402 on Base. No API key, no signup.

When to use: call it before any EVM transaction (bridge, deploy, swap) to route to the lowest-fee chain — e.g. *"Use Optimism — saves 97% vs Ethereum"*. Built for AI agents: one USDC microtransaction per call. Ships as a Node client and a stdio MCP server.

MCP server (Claude Desktop, Cursor, any MCP client)

No install needed:

"mcpServers": { "mgo-gas": { "command": "npx", "args": ["-y", "chain-ops-mgo"], "env": { "MGO_PRIVATE_KEY": "0x...", "MGO_MAX_PRICE": "10000" } } } }

Tools: get_gas_demo, get_cheapest_chain (free), get_gas_basic ($0.001), get_gas_premium ($0.002). Without MGO_PRIVATE_KEY the paid tools return the x402 payment requirements instead of data. With it (plus @chain-ops/agent-sdk and viem installed) they pay automatically, capped at MGO_MAX_PRICE micro-USDC (default 10000 = $0.01). Prefer not to run anything? The same tools are hosted at https://api.mgo.chain-ops.xyz/mcp (official MCP Registry: xyz.chain-ops/mgo).

Install (library)

Free endpoints only:

npm install chain-ops-mgo

Auto-payment (recommended for paid endpoints):

npm install chain-ops-mgo @chain-ops/agent-sdk viem

Quick Start

Free — no payment

const { getCheapestChain } = require('chain-ops-mgo');

const result = await getCheapestChain(); console.log(result); // { // chain: 'Optimism', chainId: 10, nativeToken: 'ETH', // gasPriceGwei: '0.0010', // dexSwapCostNative: '0.00000016', // dexSwapCostUsdc: 0.00039, // from the free /prices feed; omitted if unavailable // savingsVs: 'Ethereum', // savingsPercent: '97.4%' // }

Paid — auto-payment via SDK (recommended)

const { getGasBasicWithPayment } = require('chain-ops-mgo');

const data = await getGasBasicWithPayment({ account: process.env.PRIVATE_KEY, // 0x... network: 'base', });

console.log(data.recommendation.action); // "Use Optimism — saves 97.4% vs Ethereum"

The SDK handles the x402 402-handshake (parse requirements, sign the EIP-3009 USDC authorization, retry). One USDC microtransaction per call ($0.001 basic, $0.002 premium), hard-capped at maxPrice (default $0.01).

Endpoints

Function	Price	Chains	Notes
`getGasDemo()`	Free	4	Raw gas prices (native units), rate limited 10/hr
`getPrices()`	Free	—	Native token USD prices (ETH, BNB, POL, AVAX, HYPE), 60s cache
`getCheapestChain()`	Free	4	Cheapest chain for a DEX swap, USD via `getPrices()`
`getGasBasicWithPayment({ account })`	$0.001 USDC	4	Auto-pay via SDK + recommendation
`getGasPremiumWithPayment({ account })`	$0.002 USDC	9	Auto-pay via SDK + 9 chains incl. BNB, Polygon, Avalanche, zkSync, Hyperliquid
`getGasBasic({ paymentHeader })`	$0.001 USDC	4	Manual mode — bring your own x402 header
`getGasPremium({ paymentHeader })`	$0.002 USDC	9	Manual mode — bring your own x402 header

Auto-pay options

await getGasPremiumWithPayment({

account: '0x...', // private key OR a viem Account object network: 'base', // currently only 'base' maxPrice: 5_000n, // optional cap in micro-USDC ($0.005); default 10_000n });

If @chain-ops/agent-sdk is not installed, the auto-pay functions throw a clear error pointing to the install command. Free functions work without it.

Manual mode (advanced)

If you build your own x402 client, you can supply a pre-built header:

const { getGasBasic } = require('chain-ops-mgo');

const data = await getGasBasic({ paymentHeader: { 'PAYMENT-SIGNATURE': ' ' }, // or 'X-PAYMENT' for v1 });

Without a payment header, paid functions throw Error: Payment required with err.status === 402 and err.paymentInfo (the decoded PAYMENT-REQUIRED header: accepts[], resource, ...).

Payment

Uses x402 protocol on Base (eip155:8453) with USDC. No API key, no subscription, no account required.
