Pulled straight from the server with tools/list on 2026-10-17.
parse_intentread-only

Parse a plain-English swap request (e.g. "swap 100 USDC for ETH on Optimism") into a structured intent: { intent: "swap"|"unknown", entities: [{type: sellToken|buyToken|amount|chain, value, raw}] }. Backed by the live Ophis parser.

get_quoteread-only

Fetch a best-execution quote from the chain's Ophis orderbook (use a chainId from list_chains' `tradeable`). Amounts are in atoms (smallest unit, uint256 decimal string). For kind='sell' the amount is the sell amount before fee; for kind='buy' it is the desired buy amount. Returns the orderbook quote (sellAmount/buyAmount/feeAmount/validTo). Before build_order, apply slippage to the limit side by

build_orderread-only

Build a bounded, ready-to-sign CoW order on Ophis. Returns { order, signing:{domain,types,primaryType}, fullAppData, appDataHash, partnerFee, next }. The receiver is ALWAYS PINNED to the owner (proceeds cannot leave the account); this public endpoint exposes no custom-receiver option. Uses the correct per-chain settlement contract (Optimism, Unichain, Robinhood Chain, and Arc are non-canonical) an

submit_ordercan modify

Relay a PRE-SIGNED order to the chain's Ophis orderbook. Pass the exact `order` object and `fullAppData` from build_order, plus your EIP-712 `signature` and `from` (owner). The MCP holds no keys — it only forwards. Returns the order UID on success.

lookup_tierread-only

Look up a wallet's Ophis fee-rebate tier and live status (30-day volume → bronze/silver/gold/platinum, rebate %). Returns the indexer status plus the static tier ladder.

get_integrator_earningsread-only

Look up what an integrator's own-fee routing earned on indexed chains, including Arc, by appCode (the identifier you tag into appData: your widget appCode or your SDK ophisReferrer code). Returns routed volume (USD, split by chain and by sovereign-vs-hosted), the Ophis base fee charged on your flow, your OWN stacked fee, and your referral rebate paid-to-date with payout tx links. Own-fee payout la

list_chainsread-only

List configured EVM orderbook chains, split into `tradeable` (orderbook URL configured; only route get_quote/build_order to these) and `paused` (no configured orderbook URL, so those tools reject the chain). This is configuration, not a live health or liquidity check. The standalone app's externally funded NEAR networks are not orderbook chains. Each tradeable chain includes its orderbook host, GP

get_balancesread-only

Read a wallet's native-token balance plus ERC-20 balances for the given token addresses on one chain, via a public RPC (one multicall). Returns each token's symbol, decimals, raw atoms, and human-readable amount. A token address that is not an ERC-20 is reported with an `error` and does not fail the batch. Read-only; holds no keys. Supported chains are those with a public RPC (most Ophis chains).

get_portfolioread-only

Read a wallet's native and (optionally) ERC-20 balances across multiple chains at once. Pass tokensByChain (chainId -> token addresses) to include token balances; omit chainIds to scan every chain with a public RPC (max 13 chains, and at most 100 token reads total across all chains). Per-chain RPC failures are returned inline so one dead endpoint does not sink the result. Read-only; holds no keys.

get_gasread-only

Read a chain's current gas price (EIP-1559 maxFee/maxPriority suggestion when supported, plus an effective gasPrice in wei and gwei). Ophis trades are gasless for the trader, so this mainly bounds the cost of a one-time ERC-20 approval to the VaultRelayer. Read-only.

get_token_chartread-only

Fetch OHLCV price history for a token from the keyless GeckoTerminal market API (resolves the token's deepest pool, then returns candles). Use for an agent to reason about recent price action before quoting. Prices come from a single pool that may be thin or manipulated, so treat them as advisory, not a sole execution signal. The keyless tier is a shared ~30 req/min quota, so cache and do not poll

expected_surplusread-only

Estimate how much better Ophis quotes than the open market for a sell: fetches the Ophis orderbook sell-quote and a public all-DEX aggregator (KyberSwap) quote for the same input, and returns `beatBps` (+ = Ophis returns more of the buy token). Use before build_order to show the expected edge. The reference can reflect thin or manipulated liquidity, so treat beatBps as advisory, not a sole executi

resolve_tokenread-only

Resolve an ERC-20 token SYMBOL to its CANONICAL on-chain address from the trusted Ophis token list (the same curated list the swap UI uses). Use this BEFORE quoting or building so you never trade an address taken from chat, the web, or memory: a token can spoof the symbol "USDC" at a scam address, and this fails closed. Returns { found, ambiguous, canonical: {address, decimals, name} | null, match

validate_orderread-only

Offline preflight for an order you built OUTSIDE build_order (no network call, no keys). Catches the documented silent-failure modes before you sign or submit: wrong appCode (settles but earns zero rebate), wrong orderbook host (api.cow.fi silently bypasses the Ophis stack on Ophis-operated chains), wrong EIP-712 domain (signing against CoW's canonical settlement on an Ophis-operated chain yields
