Available tools 21

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

transfer

lz_transfer_build

Build signable transaction steps from a Value Transfer API quote. Takes a quoteId from lz_transfer_quote and returns pre-built transaction calldata (to, data, value) that the caller can sign and broadcast. Handles approval and bridge steps automatically.

lz_transfer_chains

List all chains supported by the LayerZero Value Transfer API. Returns 130+ chains including Solana, all EVM L1s and L2s, and their chain keys for use in lz_transfer_quote.

lz_transfer_quote

Get a cross-chain transfer quote from the LayerZero Value Transfer API. This is the newest LayerZero API (replaces deprecated Stargate REST API) supporting 130+ chains including Solana. Returns quotes with fees, estimated times, and a quote ID for building transaction steps. Use 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE as the token address for native ETH.

lz_transfer_status

Check the status of a Value Transfer API transfer by its quote ID. Returns current transfer status, source/destination transaction hashes, and delivery progress.

lz_transfer_tokens

List tokens available for cross-chain transfer via the LayerZero Value Transfer API. Optionally filter by chain. Returns token addresses, symbols, decimals, and which chains they're available on.

oft

lz_oft_list

List all available OFT (Omnichain Fungible Token) deployments registered in the LayerZero Metadata API. Returns token symbols, contract addresses, supported chains, and deployment details.

lz_oft_quote

Quote an OFT (Omnichain Fungible Token) transfer via the LayerZero Metadata API. Returns estimated fees, exchange rates, and transfer details for bridging tokens between chains using LayerZero's OFT standard.

lz_oft_send

Build transaction calldata for an OFT (Omnichain Fungible Token) send() call on any OFT contract. OFT V2 uses uint64 amountSD (shared decimals) instead of uint256 amountLD. Returns the hex-encoded calldata for OFT.send(SendParam, MessagingFee, refundAddress). The caller must first call lz_quote_fee or lz_oft_quote to get the messaging fee, then sign and broadcast this transaction with msg.value = nativeFee.

stargate

lz_stargate_quote

Quote a Stargate V2 native bridge transfer fee. Calls quoteSend() on the StargatePoolNative contract (ETH, USDC, or USDT) to get the exact LayerZero messaging fee for bridging between supported EVM chains. Returns the fee in wei and the minimum amount received after slippage. Supported tokens: ETH (Ethereum/Optimism/Arbitrum/Base), USDC (6 chains), USDT (6 chains).

lz_stargate_send

Build transaction calldata for a Stargate V2 sendToken() bridge transfer. Returns hex-encoded calldata, the target contract address, and the msg.value to include. The caller must sign and broadcast the transaction. For native ETH, msg.value = nativeFee + bridgeAmount. For ERC-20 tokens (USDC/USDT), approve the pool contract first, then msg.value = nativeFee only. Supported: ETH (4 chains), USDC (6 chains), USDT (6 chains).

broadcast

lz_broadcast_signed_tx

Broadcast a pre-signed Ethereum transaction via eth_sendRawTransaction on the source chain RPC. Use this as the canonical broadcast path for calldata produced by lz_send_message (EndpointV2.send), lz_oft_send (OFT.send), lz_stargate_send (StargatePoolNative.sendToken), and lz_transfer_build (Value Transfer API steps). Returns the transaction hash on success. The caller must construct calldata, sign locally with msg.value = nativeFee from the corresponding quote tool, then submit the RLP-encoded signed tx hex here.

chain

lz_get_chain_rpc

Get the public RPC URL for a supported chain by name. These RPC URLs are used by the server for eth_call queries against EndpointV2.

chains

lz_list_chains

List all 16 chains supported by this LayerZero MCP server with their Endpoint IDs (EIDs). Includes Ethereum, Arbitrum, Optimism, Polygon, BSC, Avalanche, Base, Solana, zkSync, Sei, Sonic, Berachain, Story, Monad, MegaETH, and Tron. EIDs are used in EndpointV2.quote() and EndpointV2.send() to identify destination chains.

deployments

lz_get_deployments

Get LayerZero V2 deployment addresses across all supported chains. Returns EndpointV2, SendLib, ReceiveLib, DVN, and Executor addresses from the LayerZero Metadata API.

dvns

lz_list_dvns

List all Decentralized Verifier Networks (DVNs) registered in the LayerZero V2 protocol. DVNs verify cross-chain messages by attesting to source chain state on the destination chain. Returns DVN names, addresses, supported chains, and configuration details.

encode

lz_encode_options

Encode LayerZero TYPE_3 options bytes for use with EndpointV2.quote() and EndpointV2.send(). TYPE_3 (version tag 0x0003) is the current standard options format for LayerZero V2. Builds binary options with executor worker ID 0x01 and option type 1 (lzReceive) with configurable gas limit and native token drop amount. Returns the hex-encoded options bytes.

message

lz_get_message

Get a LayerZero message by its GUID (Global Unique Identifier). The GUID is returned by EndpointV2.send() and can also be found in the Scan API message tracking response.

messages

lz_get_messages_by_address

Get LayerZero messages for a specific wallet address. Queries the Scan API for all messages sent or received by the given address. Returns message details including status, source/destination chains, and timestamps.

quote

lz_quote_fee

Estimate cross-chain messaging fee via LayerZero EndpointV2.quote() eth_call. Returns the native fee and LZ token fee required to send a message from the source chain to the destination endpoint. Uses the on-chain EndpointV2 contract at 0x1a44076050125825900e736c501f859c50fE728c. Selector: 0xdb9d28c6.

send

lz_send_message

Build transaction calldata for EndpointV2.send() to dispatch a cross-chain message via LayerZero V2. Returns the hex-encoded calldata that should be submitted as a transaction to the EndpointV2 contract on the source chain. The caller must sign and broadcast the transaction with msg.value set to the nativeFee from lz_quote_fee. Selector: 0x5e280f11.

track

lz_track_message

Track a cross-chain LayerZero message by the source transaction hash. Queries the LayerZero Scan API for message status: INFLIGHT, CONFIRMING, DELIVERED, FAILED, or BLOCKED. Returns the full message details including source/destination chains, GUID, and current status.

Tenzro Layerzero — questions

Answers built from our own checks of this server.

What can Tenzro Layerzero do?

It exposes 21 tools, read directly from the server on our last check. Among them: lz_broadcast_signed_tx, lz_encode_options, lz_get_chain_rpc, lz_get_deployments, lz_get_message, lz_get_messages_by_address and 15 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Tenzro Layerzero mostly used for?

Its tools cluster around transfer, oft and stargate. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Tenzro Layerzero working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 615 ms. The bar chart above shows every period we have measured.

How do I connect Tenzro Layerzero?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Tenzro Layerzero need an API key?

No. Tenzro Layerzero completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 21 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Tenzro Layerzero?

It answers our handshake in 615 ms on average, which is faster than 16% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
