Common questions

Is Mgo safe?

It passed 0 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?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.2.0) 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?

MGO — Multi-chain Gas Optimizer

An x402-native API that compares real-time gas prices across up to 9 EVM chains and recommends the cheapest one. Built for trading agents, DeFi bots, and any AI agent that needs to optimize transaction costs.

Quick Start

# 1. Install dependencies

npm install

2. Set environment variables

cp .env.example .env

Set WALLET_ADDRESS (USDC receiving wallet on Base) and CDP_API_KEY_ID/SECRET (facilitator auth)

3. Run locally (same entry point as production)

npm start

4. Test

Open in browser: http://localhost:3000/gas/demo

Tiers

Feature	Demo (Free)	Basic ($0.001)	Premium ($0.002)
Chains	4	4	9
Gas prices	Yes	Yes	Yes
Cheapest chain recommendation	No	Yes	Yes
Savings % calculation	No	Yes	Yes
Cost savings estimate	No	Yes	Yes
BNB, Polygon, Avalanche, zkSync, Hyperliquid	No	No	Yes
Rate limit	10/hr, 100/day	Unlimited	Unlimited

Endpoints

Endpoint	Payment	Description
`GET /gas/demo`	Free	Raw gas prices only (10/hr rate limit)
`GET /gas/basic`	$0.001 USDC (x402)	4-chain comparison + recommendation + savings
`GET /gas/premium`	$0.002 USDC (x402)	9-chain full comparison
`GET /prices`	Free	Native token USD prices (ETH, BNB, POL, AVAX, HYPE), 60s cache
`POST /mcp`	Free / x402	MCP Streamable HTTP endpoint (tools: `get_gas_demo`, `get_cheapest_chain`, `get_gas_basic`, `get_gas_premium`)
`GET /openapi.json`	Free	OpenAPI 3.1 spec
`GET /llms.txt`, `/skill.md`	Free	AI agent discovery files
`GET /.well-known/x402`, `/.well-known/x402.json`, `/.well-known/mcp.json`, `/.well-known/agent-card.json`	Free	Discovery metadata
`GET /health`	Free	Server health check

Payment Flow (x402 v2)

GET /gas/basic or /gas/premium → 402 with requirements in the PAYMENT-REQUIRED header (base64 JSON). A v1-shaped copy is also in the body for legacy clients.
Client signs an EIP-3009 USDC authorization on Base (eip155:8453)
Resend with PAYMENT-SIGNATURE header → facilitator (Coinbase CDP) verifies → data response with PAYMENT-RESPONSE receipt → USDC settled on-chain

If the upstream RPC / price feed is unavailable the API answers 503 and no payment is settled.

// Client example (@x402/fetch, x402 v2)

const { wrapFetchWithPayment } = require("@x402/fetch"); const { x402Client } = require("@x402/core/client"); const { ExactEvmScheme } = require("@x402/evm/exact/client"); const { privateKeyToAccount } = require("viem/accounts");

const client = new x402Client().register("eip155:*", new ExactEvmScheme(privateKeyToAccount(process.env.EVM_PRIVATE_KEY))); const paidFetch = wrapFetchWithPayment(fetch, client); const res = await paidFetch("https://api.mgo.chain-ops.xyz/gas/basic");

MCP (Claude / Cursor / any MCP client)

Remote Streamable HTTP server, no install:

"mcpServers": { "mgo-gas": { "url": "https://api.mgo.chain-ops.xyz/mcp" } } }

Also published as npm package chain-ops-mgo and in the official MCP Registry (xyz.chain-ops/mgo). Paid tools return the decoded x402 payment requirements; pay with an x402 client against the resource URL.

Operations

Access log + /stats (Upstash Redis, key via STATS_KEY; send it as x-stats-key header)
Demo rate limit and the CoinGecko price cache are shared through the same Redis
Secrets never live in this repo: see .env.example
