Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
build_transaction Build the unsigned transaction for a quote ~141
Turn a quoteId from get_quote into the UNSIGNED transaction the user's own wallet must sign: EVM {chainId, to, data, value in wei, optional ERC-20 approval to send first} or Solana {serializedTx base64}. Includes plain-language signing steps. The LayerHop MCP server holds no private keys and never signs or broadcasts transactions. Only use this when the user has their own signer and explicitly wants raw transaction data, after they confirmed the quote; otherwise give them the swap link.
| Name | Type | Req | Description |
|---|---|---|---|
| quoteId | string | yes | quoteId from get_quote (starts with "q_"). Quotes expire after a short time (see expiresAt). |
No output schema declared.
No examples provided.
get_order_status Get swap/bridge order status ~102
Check the status of a swap or bridge after the source transaction was sent: pending, filled (funds delivered), refunded, failed, or unknown (some same-chain providers; check the tx on an explorer). Read-only.
| Name | Type | Req | Description |
|---|---|---|---|
| provider | string | yes | The provider of the quote that was executed (the `provider` field from get_quote / build_transaction). |
| txHash | string | yes | Source-chain transaction hash (EVM) or signature (Solana). |
No output schema declared.
No examples provided.
get_quote Get swap/bridge quotes ~588
Get the best price to swap or bridge tokens, within one chain or across chains (EVM <-> Solana). Asks every liquidity provider and returns the best quote plus alternatives with human-readable amounts, minimum received after slippage, fees (LayerHop fee, partner fee, provider fee, gas) and ETA. Returns a quoteId (valid until expiresAt) and a layerhop.com swapLink a human can open to review and sign. Read-only: The LayerHop MCP server holds no private keys and never signs or broadcasts transactions. Always show the user the fees and output and get confirmation before proceeding.
| Name | Type | Req | Description |
|---|---|---|---|
| amount | string|number | yes | Amount to send in HUMAN units of fromToken as a decimal string, e.g. "100" for 100 USDC or "0.05" for 0.05 ETH. NOT base units/wei/lamports. Must be greater than 0. |
| fromChain | string|number | yes | Source chain: slug ("base", "solana", "ethereum", "arbitrum"...) or numeric chain id (Solana is 7565164). See list_chains. |
| fromToken | string | yes | Token to send (source) token: symbol from list_tokens ("USDC", "ETH", "SOL") or the token contract address / SPL mint. Use "native" for the chain's gas coin. |
| fromTokenDecimals | integer | – | Only needed when fromToken is an address that is not in list_tokens: the token's decimals (e.g. 6 for USDC, 18 for most ERC-20s). |
| recipient | string | – | Address that receives funds on the destination chain. Defaults to sender when both chains use the same VM; REQUIRED for EVM <-> Solana. |
| sender | string | yes | Wallet address that sends the funds on the source chain (0x... for EVM, base58 for Solana). Only used to build the quote; no access is needed. |
| slippageBps | integer | – | Max slippage in basis points (1 bp = 0.01%). Default 50 (= 0.5%). |
| toChain | string|number | yes | Destination chain: slug ("base", "solana", "ethereum", "arbitrum"...) or numeric chain id (Solana is 7565164). See list_chains. |
| toToken | string | yes | Token to receive (destination) token: symbol from list_tokens ("USDC", "ETH", "SOL") or the token contract address / SPL mint. Use "native" for the chain's gas coin. |
| toTokenDecimals | integer | – | Only needed when toToken is an address that is not in list_tokens: the token's decimals (e.g. 6 for USDC, 18 for most ERC-20s). |
No output schema declared.
No examples provided.
get_swap_link Get a layerhop.com swap link ~386
Create a https://layerhop.com/swap link prefilled with the swap, which the user opens to review the live quote and fees and sign in their own wallet. This is the default, safest way to execute a swap. The LayerHop MCP server holds no private keys and never signs or broadcasts transactions. The amount is in human units.
| Name | Type | Req | Description |
|---|---|---|---|
| amount | string|number | – | Amount to send in HUMAN units of fromToken as a decimal string, e.g. "100" for 100 USDC or "0.05" for 0.05 ETH. NOT base units/wei/lamports. Must be greater than 0. |
| fromChain | string|number | yes | Source chain: slug ("base", "solana", "ethereum", "arbitrum"...) or numeric chain id (Solana is 7565164). See list_chains. |
| fromToken | string | yes | Token to send (source) token: symbol from list_tokens ("USDC", "ETH", "SOL") or the token contract address / SPL mint. Use "native" for the chain's gas coin. |
| recipient | string | – | Optional destination address to prefill (the user can still edit it). |
| slippageBps | integer | – | Max slippage in basis points (1 bp = 0.01%). Default 50 (= 0.5%). |
| toChain | string|number | yes | Destination chain: slug ("base", "solana", "ethereum", "arbitrum"...) or numeric chain id (Solana is 7565164). See list_chains. |
| toToken | string | yes | Token to receive (destination) token: symbol from list_tokens ("USDC", "ETH", "SOL") or the token contract address / SPL mint. Use "native" for the chain's gas coin. |
No output schema declared.
No examples provided.
list_chains List supported chains ~46
List every blockchain LayerHop can swap from or to: slug, numeric chain id, name, VM type (evm or svm = Solana) and native coin. Read-only.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
list_orders List orders for a wallet ~116
List LayerHop orders (swaps built or submitted through LayerHop) where the address is the sender or recipient, newest first, with status. Public data (addresses only). Read-only.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | Wallet address (EVM 0x... or Solana base58). |
| cursor | string | – | nextCursor from a previous list_orders call, for the next page. |
| limit | integer | – | Max orders to return (default set by the API). |
| status | string | – | Only orders with this status. |
No output schema declared.
No examples provided.
list_tokens List tokens on a chain ~94
List LayerHop's built-in tokens on one chain (symbol, contract address or mint, decimals). Symbols can be used directly in get_quote; other tokens can be quoted by address. Read-only.
| Name | Type | Req | Description |
|---|---|---|---|
| chain | string|number | yes | The chain: slug ("base", "solana", "ethereum", "arbitrum"...) or numeric chain id (Solana is 7565164). See list_chains. |
No output schema declared.
No examples provided.
report_submitted Report a broadcast transaction ~127
Tell LayerHop that the user's wallet broadcast the transaction for a quoteId, so the order is tracked (status, webhooks). Call this once after broadcasting, with the EVM tx hash (0x + 64 hex) or Solana signature. Idempotent. Does not sign or send anything.
| Name | Type | Req | Description |
|---|---|---|---|
| quoteId | string | yes | quoteId from get_quote (starts with "q_"). Quotes expire after a short time (see expiresAt). |
| txHash | string | yes | Source-chain transaction hash (EVM 0x...) or Solana signature (base58). |
No output schema declared.
No examples provided.
simulate_transaction Dry-run a quote's transaction ~124
Build the transaction for a quoteId and dry-run it on-chain (EVM eth_call + gas estimate from the sender; Solana simulateTransaction) without sending anything or recording an order. Reports whether it would succeed, gas / compute units, whether an ERC-20 approval is still needed, and the error if it would fail. Read-only: The LayerHop MCP server holds no private keys and never signs or broadcasts transactions.
| Name | Type | Req | Description |
|---|---|---|---|
| quoteId | string | yes | quoteId from get_quote (starts with "q_"). Quotes expire after a short time (see expiresAt). |
