## Tools (as reported by the server, not verified)

- `list\_chains`: 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.
- `list\_tokens`: 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.
- `get\_quote`: 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. Retur
- `build\_transaction`: 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 s
- `simulate\_transaction`: 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
- `report\_submitted`: 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.
- `get\_order\_status`: 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.
- `list\_orders`: 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.
- `get\_swap\_link`: 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 amoun
- `create\_deposit\_address`: Create an address the user sends tokens to; every deposit is swapped/bridged and delivered as toToken on toChain to recipient. No wallet connection or signing needed. Non-custodial: the address belongs to the liquidity provider \(Relay\), LayerHop never holds funds. Tell the user: send ONLY srcToken o
- `list\_deposit\_addresses`: List the deposit addresses of the API key's account and mode \(live or test\), newest first: address, route, status, deposit count. Needs a LayerHop API key. Read-only.
- `get\_deposit\_address`: Get one deposit address with its 20 most recent deposits \(orders, quoteId starting with dep\_\): amount deposited and delivered, status \(submitted, pending, filled, refunded, failed\) and tx hashes. Tell the user: send ONLY srcToken on srcChain to the address \(other tokens or chains may be lost for goo
- `refresh\_deposit\_address`: Ask LayerHop to check a deposit address for new deposits right away \(instead of waiting for the next scheduled check\). Call it when the user says they sent funds, then call get\_deposit\_address after \~15-30 s. Needs a LayerHop API key.
- `disable\_deposit\_address`: Disable a deposit address: LayerHop stops tracking it \(no more orders or webhooks for it\). The provider may still process funds sent to it later, so the user must stop using it. Cannot be undone. Confirm with the user first. Needs a LayerHop API key.
- `simulate\_deposit`: TEST MODE ONLY \(lh\_test\_ key and a test deposit address\): record a fake deposit so the integration can be tested end to end; it becomes a test order that settles with webhooks. The amount decides the outcome: base units ending in 4001 -\> refunded, 4002 -\> failed, anything else -\> filled. Moves no re
