About Evmscope

Evmscope is an EVM data toolkit for AI agent developers, traders, and researchers, available as a CLI or MCP server across seven chains. Its read-only on-chain tools cover prices, wallets, DeFi, and safety checks without API keys or initial setup.

Key features

01Query token prices, balances, and portfolios
02Compare gas and get swap or bridge routes
03Inspect yields, TVL, and whale transfers
04Check honeypot risks and simulate transactions
05Look up NFTs, governance, and block details
06Use CLI or MCP in read-only mode

Use cases

01Add live on-chain queries to AI agents
02Research tokens, wallets, and DeFi protocols from a terminal
03Compare quotes or assess token risks before a swap

MCP support

As an MCP server, it exposes 26 read-only on-chain tools across seven EVM chains to AI clients. It works without API keys.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config

{
  "mcpServers": {
    "evmscope": {
      "command": "npx",
      "args": [
        "-y",
        "evmscope"
      ]
    }
  }
}

Run commandnpx -y evmscope

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Details

From the project README

evmscope

한국어 | 中文 | 日本語 | Español | Русский

EVM blockchain intelligence toolkit. 26 tools across 7 chains — use as a CLI or MCP server. Token prices, gas comparison, swap quotes, yield rates, honeypot detection, bridge routes, tx simulation, NFT lookup, governance proposals, portfolio tracking, and more.

Why evmscope?

AI agents like Claude and GPT cannot access real-time blockchain data. Ask "What's the ETH price?" or "Show me this wallet's balance" and you'll get "I can't access real-time data."

evmscope solves this by giving AI agents direct access to 26 on-chain tools via the MCP protocol — token prices, wallet balances, DeFi yields, whale tracking, honeypot detection, and more. No API keys, no setup, just connect and go.

Who is it for?

User	Use Case
AI agent developers	Connect as MCP server to give AI on-chain analysis capabilities
Crypto traders & researchers	Query tokens, wallets, and protocols directly from the terminal
DeFi users	Safety tools — honeypot detection, approval status checks, whale tracking

Features

26 tools — Price, gas compare, swap quote, yield rates, honeypot detection, bridge routes, tx simulation, event logs, token holders, approval status, TVL, whale tracking, balance, token info, ENS, tx status, tx decode, ABI lookup, address ID, NFT info, NFT metadata, governance proposals, block info, token transfers, portfolio
7 EVM chains — Ethereum, Polygon, Arbitrum, Base, Optimism, Avalanche, BSC
49 built-in tokens — ETH, USDC, USDT, WETH, LINK, UNI, AAVE, ARB, OP, PEPE, and more
30+ labeled addresses — Exchanges, DeFi protocols, bridges, whale wallets
Zero config — No API keys required. Works out of the box with free public APIs
Read-only — No transaction execution. Zero risk of fund loss
Dual mode — CLI for direct terminal use, MCP server for AI agent integration
