chain-ops MGO

Find and compare gas prices across multiple EVM chains to identify the cheapest option for transactions and contract deployments.

Security Scan

The skill's stated purpose (compare gas across EVM chains) matches the API endpoints listed, but there are several unexplained gaps (unknown source, no homepage, paid endpoints with no payment/integration details and no request formats) that make it unclear how it would operate in practice.

Purpose & Capability

The skill's name/description align with the listed endpoints (gas demo/basic/premium). However the metadata lacks a maintained homepage and the source is 'unknown', which reduces trust. The presence of paid endpoints (x402 on Base) is not justified by any required credentials or integration instructions in the SKILL.md.

Instruction Scope

SKILL.md only provides a base URL and three endpoints; it does not instruct the agent to read local files or request any environment variables. But it is vague: no example request payloads, no response schemas, no guidance about what transaction details (if any) should be sent, and no privacy guidance about what user data will be transmitted to the external API.

Install Mechanism

Instruction-only skill with no install spec and no code files — lowest install risk. The agent will call an external HTTPS API; nothing is written to disk by the skill itself.

Credentials

The skill requests no environment variables or credentials, which is proportionate. However SKILL.md mentions paid endpoints using an on-chain payment protocol (x402 on Base) but provides no mechanism for how the agent or user would make those payments (no wallet integration instructions, no API keys, no payment flow). That mismatch is unexplained and could cause unexpected behavior or confusion.

Persistence & Privilege

always is false and the skill is user-invocable; it does not request persistent presence or modify other skill configs. Autonomous invocation is allowed by default but is not combined with other high-risk factors here.

What to consider before installing

This skill appears to point at a multi-chain gas API and is instruction-only, but the publisher and homepage are missing and paid endpoints are mentioned without any payment or request details. Before installing or using it: 1) verify the API provider (check the GitHub repo and the mgo.chain-ops.xyz domain for legitimacy); 2) prefer calling the free demo endpoint first to confirm responses and format; 3) never provide private keys or wallet secrets — the SKILL.md does not request them, but paid on-chain calls could require a wallet outside the skill; 4) be cautious about allowing autonomous use that might trigger paid requests — restrict usage to user-invoked calls until you understand the payment flow; 5) if you rely on this for production decisions, ask the maintainer for API docs (request/response examples, rate limits, and a privacy policy) before trusting it.

MGO — Multi-chain Gas Optimizer

Use this skill when the agent needs to find the cheapest EVM chain for a transaction, compare gas prices across chains, or optimize transaction costs.

When to use

• "Which chain is cheapest for gas right now?"
• "Compare gas prices across EVM chains"
• "I want to send a transaction — where should I do it?"
• "Find the cheapest chain to deploy a contract"
• "How much will this transaction cost on Base vs Ethereum?"
