A hosted Ethereum and Base chain-data MCP server with no RPC key

The popular EVM MCP servers, such as mcpdotdirect's evm-mcp-server (60+ networks), run on your machine with your own RPC settings, and the Coinbase-based Base MCP server needs developer-platform credentials. They can also sign transactions. Tanod's /mcp/chain is read-only and hosted: one URL, no RPC key, no wallet, for an agent that only needs to look things up on Ethereum or Base.

What's on it (19 tools)

• Accounts: native and ERC-20 balances, a portfolio view, token allowances, NFT owner lookup (portfolio).
• Tokens and prices: token metadata, Chainlink prices, Uniswap swap quotes and OHLCV candles from on-chain swaps (candles, quotes).
• Transactions: status and details, decoded event logs, decoded calldata, gas, blocks and the block at a timestamp (calldata).
• Names and safety: ENS resolution and records, proxy detection, a pre-interaction contract check and OFAC address screening.

Try asking

• "What are vitalik.eth's ETH and USDC balances on Base?"
• "Decode the logs of this transaction and tell me what happened."
• "Give me ETH/USDC hourly candles for the last day."

Limits and caveats

Ethereum mainnet and Base only, read-only: it never holds keys or signs anything. Results come from public RPCs and can lag a few blocks. The full Tanod server with all 120+ tools stays at https://tanod.dev/mcp.
