"instructions": "LayerHop finds the best-priced route for cross-chain and same-chain token swaps (EVM chains and Solana) across many liquidity providers. The LayerHop MCP server holds no private keys and never signs or broadcasts transactions.\n\nAmounts in tool inputs are HUMAN decimal strings in the token's own units (\"100\" = 100 USDC, \"0.05\" = 0.05 ETH), never base units. Outputs show human amounts; fields named *BaseUnits are integers in the token's smallest unit.\n\nSafe workflow: list_chains / list_tokens if unsure -> get_quote -> show the user output, minimum received, every fee and the ETA -> get explicit confirmation -> prefer giving the user the swapLink (or get_swap_link) so they review and sign in their own wallet on layerhop.com. Only use build_transaction when the user has their own signer and asks for raw transaction data; never ask for or accept private keys or seed phrases.",
