One gateway.
Every answer from the chain.

Nerby Protocol turns plain-language questions from your AI into live blockchain queries, and hands the results straight back.

01 · How it works

A question goes in. Chain data comes out.

Nerby Protocol is a small server that speaks MCP, the open standard AI apps use to call tools. It sits between your AI and the blockchain nodes.

Step 1

Connect

Add one URL to your AI client as an MCP server. No account, no API key, nothing to install.

Step 2

Ask

Ask in plain words. Your AI picks the right tool and Nerby Protocol queries a live node on the network you named.

Step 3

Decide

The answer comes back as structured data your AI can explain. For transactions you get a dry-run and an unsigned transaction — the decision and the signature stay with you.

02 · Tools

Eleven tools, all read-only.

Your AI chooses among these on its own. The example prompts show the kind of question each one answers.

Tool	What it does	Try asking
`list_networks`	Lists the chains you can query, with chain IDs and native currency.	“Which networks can you reach?”
`get_balance`	Native balance of any address: ETH, POL or BNB.	“How much ETH is in 0xd8dA…6045?”
`get_token_balance`	ERC-20 balance of a holder, with the token symbol and decimals.	“How much USDC does this wallet hold on Base?”
`get_block`	A block header: number, hash, time, gas used, base fee, transaction count.	“What is the latest block on Arbitrum?”
`get_transaction`	A transaction and its receipt: sender, recipient, value, status, fee, logs.	“Did this transaction succeed, and what did it cost?”
`get_logs`	Event logs from a contract over a block range, up to 2,000 blocks per call.	“Show recent Transfer events from this token.”
`get_code`	Whether an address is a contract, and how large its bytecode is.	“Is this address a contract or a wallet?”
`read_storage`	The raw 32-byte value of any storage slot.	“What is in slot 0 of this contract?”
`call_contract`	Calls any read-only function from its Solidity signature and decodes the result.	“Call totalSupply() on this token.”
`get_gas_price`	Current gas price and priority fee, in gwei.	“What is gas on Ethereum right now?”
`simulate_transaction`	Dry-runs a transaction: success or revert reason, gas and fee estimate, and the unsigned transaction to review.	“Would sending 0.1 ETH to this address go through?”

03 · Networks

Seven chains, one endpoint.

Every tool works the same way on every network. Name the chain in your question and your AI passes it along.
