What Universal Blockchain MCP does

This MCP server exposes over 380 tools for direct blockchain interaction. It connects assistants to decentralized protocols like Uniswap and Aave, along with centralized exchanges Bybit and Binance. Built-in security checks evaluate smart contracts against honeypots via GoPlus before transactions run.

The repository bundles analytics tools covering CoinGecko and DefiLlama metrics. It also incorporates the x402 payment protocol. That mechanism lets autonomous agents handle micropayments and buy web API access directly on EVM or Solana chains. Communication works over stdio and HTTP transports.

Running this package requires Node.js version 18 or higher. Without that environment, the npx runner fails immediately.

What it helps with

query token prices and market sentiment from CoinGecko
scan smart contracts for honeypot risks through GoPlus
execute token swaps using 1inch or ParaSwap aggregators
transfer assets across chains with Stargate and Wormhole
enable autonomous agent micropayments via the x402 protocol

Example prompts for the agent

Check this contract address for honeypot risks using GoPlus
Fetch the current crypto fear and greed index
Find the best swap route from ETH to USDC on Arbitrum
