Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢list_chains
Chains available right now, which ids can be a source or a destination, and featured tokens.
Input Schema
{
"type": "object",
"properties": {},
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢search_tokens(direction, chainId, query, limit, offset)
Find a token address and decimals by symbol, name or address.

}🟢get_quote(fromChainId, fromToken, toChainId, toToken, amount, ...)
Estimate a swap. side "from" (default) quotes spending `amount`; side "to" quotes receiving `amount`. A quote is an estimate, not a funding instruction.

}🟡create_swap(fromChainId, fromToken, toChainId, toToken, amount, ...)
Create a durable order that spends `amount` of fromToken. Returns the deposit address and exact amount to send. Confirm with the user first. Never retry after a timeout or error: another call creates another order.

}🟢get_swap(orderId, sessionId)
Current status and customerState of an order. Amounts are atomic; *Decimals fields give scale.
Input Schema

"$schema": "http://json-schema.org/draft-07/schema#"
}🟡set_refund_address(orderId, sessionId, refundAddress)
Only when get_swap shows customerState { kind: "action_required", action: "refund_address" }. Saves one immutable destination; it does not start a transfer by itself.
