Skill: dawsbot/eth-labels (version 1.0.1)

# eth-labels Look up 170,000+ labeled crypto addresses and tokens across EVM chains (Ethereum, Base, Arbitrum, Optimism, BSC, and more). Identify who owns an address, search for labeled accounts, check balances, and discover token metadata — all via the eth-labels MCP server. ## When to use Use this skill when: - User asks "who owns this address" or "what is this address" - Looking up wallet labels (exchanges, protocols, DAOs, known entities) - Identifying token contracts and metadata - Searching for addresses by label/name - Checking balances across EVM chains - Researching crypto transactions or addresses ## Setup ### Install via GitHub (recommended) Clone the repository and build the MCP server: ```bash git clone https://github.com/dawsbot/eth-labels.git cd eth-labels/mcp npm install npm run build ``` Then add to your MCP client config (e.g., Claude Desktop `~/Library/Application Support/Claude/claude_desktop_config.json`): ```json { "mcpServers": { "eth-labels": { "command": "node", "args": ["/path/to/eth-labels/mcp/dist/index.js"] } } } ``` Replace `/path/to/eth-labels` with the actual path where you cloned the repo. ### Alternative: Run directly from source For development or testing, you can run the MCP server directly without building: ```bash cd eth-labels/mcp npx tsx index.ts ``` Add to MCP config: ```json { "mcpServers": { "eth-labels": { "command": "npx", "args": ["tsx", "/path/to/eth-labels/mcp/index.ts"] } } } ``` ## Available tools (via MCP) The MCP server provides these tools: ### `lookup_account` Look up an address to find its label and metadata. **Parameters:** - `address` (string, required): Ethereum address (0x...) - `chainId` (number, optional): Chain ID to filter results (1=Ethereum, 8453=Base, 42161=Arbitrum, 10=Optimism, 56=BSC) **Returns:** Array of account labels with chain info ### `lookup_token` Look up a token contract address to get metadata (name, symbol, website, image). **Parameters:** - `address` (string, required): Token contract address (0x...) - `chainId` (number, optional): Chain ID to filter results **Returns:** Array of token metadata ### `search_labels` Search for addresses by label/name (e.g., "Coinbase", "Uniswap"). **Parameters:** - `query` (string, required): Search term (case-insensitive, partial match supported) - `chainId` (number, optional): Chain ID to filter results - `limit` (number, optional): Max results to return (default: 20) **Returns:** Array of matching accounts ### `get_balance` Check ETH balance for an address on any EVM chain. **Parameters:** - `address` (string, required): Address to check - `chainId` (number, optional): Chain ID (default: 1 for Ethereum mainnet) - `rpcUrl` (string, optional): Custom RPC endpoint **Returns:** Balance in ETH (formatted) ## Supported chains - **Ethereum** (chainId: 1) - **Base** (chainId: 8453) - **Arbitrum** (chainId: 42161) - **Optimism** (chainId: 10) - **Binance Smart Chain** (chainId: 56) View all labeled accounts by chain at: https://eth-labels.com/accounts ## Public API alternative If you prefer REST API over MCP, use the public API: - **Swagger docs:** https://eth-labels.com/swagger - **View labeled accounts:** https://eth-labels.com/accounts?chainId=1 ## Data sources Labels are scraped from blockchain explorers (Etherscan, Basescan, Arbiscan, Optimistic Etherscan, BscScan) and refreshed regularly. ## Examples **Look up Vitalik's address:** ``` lookup_account(address=[REDACTED_SECRET], chainId=1) ``` **Search for Coinbase addresses:** ``` search_labels(query="Coinbase", limit=10) ``` **Check balance on Base:** ``` get_balance(address=[REDACTED_SECRET], chainId=8453) ``` ## Repository https://github.com/dawsbot/eth-labels ## License MIT
