  • address_reportOne-call snapshot of any Base address: ETH balance, USDC balance, transaction count, and whether it is a smart contract or a regular wallet.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    One-call snapshot of any Base address: ETH balance, USDC balance, transaction count, and whether it is a smart contract or a regular wallet. Use it to sanity-check a counterparty or a payment address before sending funds. Input: a 0x address.

    Description, as the server wrote it
    Current gas price on the Base network (Coinbase's Ethereum L2), in gwei and wei, read live from a Base RPC node. Use before sending a Base transaction or estimating its cost. Takes no input.

    • Nothing in its name or description says what it does, so it is counted as a write.

    Description, as the server wrote it
    How much of an ERC-20 token a wallet holds on Base, returned both human-formatted (using the token's decimals) and raw. Pass the token contract address and the holder address, both 0x + 40 hex. Example: USDC 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913.

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    ERC-20 token metadata on Base, read on-chain: name, symbol, decimals, and total supply, plus whether the address really behaves like an ERC-20. Use it to verify a token contract before trusting or displaying it. Input: the token contract address (0x + 40 hex).

  • tx_statusLook up a Base transaction by hash and report whether it is pending, succeeded, or failed, with from, to, value, block number, and gas used.No findings

    Why it is in this group

    • The name "tx_status" says "status": a word for reading.
    Description, as the server wrote it
    Look up a Base transaction by hash and report whether it is pending, succeeded, or failed, with from, to, value, block number, and gas used. Use it to confirm a payment or contract call landed. Input: the transaction hash (0x + 64 hex; the 0x is optional).

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
