Run instant smart contract reads in Claude Desktop

This tool suite executes live smart contract reads directly from the blockchain when you ask your agent to check a balance or query a function. It uses `eth_call` to run the message call immediately and `eth_getCode` to verify the contract bytecode is actually there. You get raw, accurate data without leaving your conversation. This is perfect for debugging protocol integrations or checking multi-sig wallet states on the fly.

Calculate precise transaction costs

This tool suite calculates precise transaction costs before your agent submits any transaction payload. It queries `eth_gasPrice` and runs `eth_estimateGas` to see exactly what a transaction will cost right now. This keeps your deployment scripts and manual transactions optimized. You see the real cost metrics before you write any code or sign a payload.

Pull block and transaction receipts

This tool suite tracks transaction finality and fetches block confirmations directly inside your workspace. The MCP Server lets your agent fetch the exact status of any transaction hash using `eth_getTransactionReceipt` or check block details with `eth_getBlockByNumber`. If you are debugging a stuck transaction, the agent pulls `eth_getTransactionCount` to check the current nonce. You get the ground truth directly from the mainnet.

Yes, but it requires a signed transaction payload. The agent uses `eth_sendRawTransaction` to broadcast a transaction you have already signed locally. The MCP server itself does not hold your private keys, keeping your funds safe.

The agent calls `get_suggested_gas_fees` to pull current EIP-1559 fee recommendations. It pairs this with `eth_estimateGas` to give you a highly accurate dry-run cost. This prevents out-of-gas errors during contract deployments.

You can search historical logs by having your agent run `eth_getLogs` with target topics. For live monitoring, the server supports `eth_newFilter` and `eth_getFilterChanges` to poll for new events. This lets you track transfers or mints in real time.

This server only handles public blockchain queries, transaction hashes, and signed payloads. Your Infura API key is stored locally on your machine and never shared with third parties. No private keys or unencrypted transaction data ever leave your local environment.
