MGO — Multi-chain Gas Optimizer

Overview

MGO — Multi-chain Gas Optimizer is a Model Context Protocol server that helps you find the cheapest EVM chain across up to 9 networks, showing exact savings percentages. Any MCP-compatible AI assistant can call its tools directly, letting the model decide when to use them during conversations or agent runs.

You can run MGO in two ways: connect to the hosted endpoint at https://x402-gas-api.vercel.app/mcp with no setup, or install it locally via npx -y chain-ops-mgo. The server runs on a pay-per-call model via x402 on Base, requires no authentication, and is published as v1.0.0 under the MIT license. Source code is available at dlrjsdl200-byte/mgo-mcp-server on GitHub.

MGO is listed under Development on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and others across the ecosystem. If you maintain this project, claim this listing to verify ownership and keep information current.
