1inch MCP server

• aquaFree

  1inch Aqua (shared-liquidity market making): position analytics plus maker position writes. Write actions (OAuth, or WalletConnect + signed 1inch ToS (pass walletSessionToken after MCP session rotation); non-custodial — the user's wallet signs): create_position (two-phase: call once for a preview + previewRef, then again with confirmed:true), close_position (confirmed:true; closing is permanent). Anonymous writes execute only via WalletConnect (execute=false is rejected). REQUIRED: "action" — read actions (no OAuth): maker_stats, list_maker_strategies, strategy_overview, strategy_activity, strategy_volume, list_opened. Read the resource file://1inch-mcp/guides/aqua-workflow for per-action examples, priceRange semantics, and maker position flows. Raw HTTP: product_api with path "/aqua/v1.0/strategies/...".

• authenticateFree

  Call this to start or confirm 1inch Business login. HTTP 401 means you are still anonymous (initialize 200 is not login). After OAuth, call again until the result is authenticated: true with organizationId. Then use swap, orderbook, product_api, or debug. Do not treat a PaymentRequired / x402 result as login.

• debugFree

  [Requires authentication] Call the authenticate tool first to start or confirm 1inch Business login (initialize 200 is still anonymous). If authenticate or this tool returns HTTP 401, complete OAuth, then retry. Look up production API request logs for your 1inch Business organization to troubleshoot integration issues. Results are always scoped to your authenticated organization. Two modes: 1) By request id: pass requestId (the x-request-id header returned on 1inch API responses). Optionally narrow startTime/endTime (defaults: last 24 hours ending now). 2) Logs in a time window: omit requestId and pass both startTime and endTime (RFC3339). Optionally set logLevel ("info", "warn", or "error") to filter by severity; omit to return all levels. Limits: each call covers at most a 24-hour window; how far back you can query depends on your plan's log retention.

• get_exampleFree

  Get the full source code of an SDK example. Use list_examples first to see available examples.

• list_examplesFree

  List all available SDK code examples. Returns example names that can be used with get_example tool.

• orderbookFree

  [Requires authentication] Call the authenticate tool first to start or confirm 1inch Business login (initialize 200 is still anonymous). If authenticate or this tool returns HTTP 401, complete OAuth, then retry. Limit orders via the 1inch Orderbook API (v4.1). IMPORTANT: The "action" parameter is REQUIRED. Must be one of: "build", "create", "list", "cancel". Actions with example parameters: 1. build (recommended first step): { "action": "build", "chain": 1, "makerAsset": "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48", "takerAsset": "0xdAC17F958D2ee523a2206206994597C13D831ec7", "makingAmount": "1000000", "takingAmount": "990000", "makerAddress": "0x..." } Optional: expirationSeconds (default 604800 = 7 days). With an active WalletConnect session, the order is signed and submitted automatically (set execute=false to return typed data only). 2. create (after signing typedData from build): { "action": "create", "chain": 1, "orderHash": "0x...", "signature": "0x...", "orderData": { ... } } 3. list (query orders): - By maker: { "action": "list", "chain": 1, "listMode": "by_maker", "makerAddress": "0x..." } - By hash: { "action": "list", "chain": 1, "listMode": "by_hash", "orderHash": "0x..." } - Browse: { "action": "list", "chain": 1, "listMode": "all", "limit": 10 } 4. cancel (inspect + guidance): { "action": "cancel", "chain": 1, "orderHash": "0x..." } Typical flow: build -> sign typedData -> create (or one build call when WalletConnect is connected — order signed and submitted automatically). The maker asset may require a one-time ERC-20 approval for the Limit Order Protocol; it costs native gas even though the limit order itself is gasless. When a build response includes an "approval" block, tell the user upfront (approval.estimatedCost holds the estimated cost in native units) and broadcast the included approveTx before signing. With WalletConnect, the approve is sent automatically — "approvalTxSent": true means the first wallet prompt was the one-time approval. Requires authentication. For raw HTTP access, use product_api.

• product_apiFree

  [Requires authentication] Call the authenticate tool first to start or confirm 1inch Business login (initialize 200 is still anonymous). If authenticate or this tool returns HTTP 401, complete OAuth, then retry. Call any 1inch product API endpoint using the authenticated user's credentials (base URL is the unified gateway, e.g. https://api.1inch.com). Call authenticate first. Anonymous sessions get HTTP 401 (OAuth), not x402. After a real org login, quota-exhausted routes may return a PaymentRequired tool result; retry with a signed payment in _meta["x402/payment"] (batch-settlement scheme only — see file://1inch-mcp/guides/x402-payments). Do not treat PaymentRequired as login. Optional: if your client can read MCP resources, file://1inch-mcp/guides/api-index has live Swagger links and extra gateway notes (mirrors business.1inch.com/portal/llms.txt). Common chain IDs: Ethereum=1, BNB=56, Polygon=137, Arbitrum=42161, Optimism=10, Base=8453, Avalanche=43114, Gnosis=100, zkSync=324, Linea=59144, Sonic=146, Unichain=130, Cronos=25, Monad=10143, Solana=501 (where applicable). Gateway products (use these path prefixes with this tool): - Portfolio: /portfolio/portfolio/v5.0/... — example path="/portfolio/portfolio/v5.0/general/current_value", query={"addresses":"0x..."}; token metrics path="/portfolio/portfolio/v5.0/tokens/metrics", query={"addresses":"0x...","timerange":"1year"} - Balance: /balance/v1.2/{chainId}/... — example path="/balance/v1.2/1/balances/0x..." - Spot Price: /price/v1.1/{chainId} — example path="/price/v1.1/1", method="POST", body={"tokens":["0x..."],"currency":"USD"} - Token: /token/v1.4/{chainId}/... — example path="/token/v1.4/1/search", query={"query":"USDC"} (prefer v1.4; older v1.2 chain search is deprecated in OpenAPI) - Token Details: /token-details/v1.0/details/{chain}/{tokenAddress} — example path="/token-details/v1.0/details/1/0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48" - Gas Price: /gas-price/v1.6/{chainId} — example path="/gas-price/v1.6/1" - Swap (Classic): /swap/v6.1/{chainId}/... — example path="/swap/v6.1/1/quote", query={"src":"0x...","dst":"0x...","amount":"..."} (exact query names per OpenAPI) - Orderbook: /orderbook/v4.1/{chainId}/... — example path="/orderbook/v4.1/1/all", query={"page":"1","limit":"10"} - Fusion (Intent): /fusion/orders/v2.0/..., /fusion/quoter/v2.0/..., /fusion/relayer/v2.0/... — example path="/fusion/quoter/v2.0/1/quote/receive" with required query params from spec - Fusion+ (Cross-chain): /fusion-plus/orders/..., /fusion-plus/quoter/..., /fusion-plus/relayer/... — example path="/fusion-plus/quoter/v1.2/quote/receive" with required params; equivalent routes also exist under /cross-chain/orders|quoter|relayer - History: /history/v2.0/history/{address}/events — example path="/history/v2.0/history/0x.../events", query={"chainId":"1","limit":"50","tokenAddress":"0x..."} (optional tokenAddress filters by contract; response shape uses items[].details.txHash — not raw event logs) - Traces: /traces/v1.0/chain/{chainId}/block-trace/{blockNumber}/tx-hash/{txHash} — example path="/traces/v1.0/chain/1/block-trace/18000000/tx-hash/0x..." (not /transaction/{hash}) - NFT: /nft/v2/... — example path="/nft/v2/byaddress", query={"chainIds":"1","address":"0x..."} - Charts: /charts/v1.0/chart/line/{token0}/{token1}/{period}/{chainId} — example path="/charts/v1.0/chart/line/0x.../0x.../24H/1" (period: 24H, 1W, 1M, 1Y, AllTime; not a separate timerange query) - Domains: /domains/... — example path="/domains/v2.0/lookup", query={"name":"vitalik.eth"} - Aqua (strategy analytics): /aqua/v1.0/strategies/... — example path="/aqua/v1.0/strategies/opened", query={"limit":"100"}; maker stats path="/aqua/v1.0/strategies/makers/0x.../stats". Prefer the dedicated "aqua" tool when Unleash flag mcp-service.tool.aqua is enabled; otherwise use product_api for raw HTTP. - Tx Gateway: /tx-gateway/... — example path="/tx-gateway/v1.1/1/broadcast", method="POST", body={...} - Web3 RPC: /web3/{chainId}/... — JSON-RPC over HTTP POST to an EVM (or Solana 501) node; Gateway exposes e.g. 1,10,25,56,100,130,137,143,146,324,501,8453,42161,43114,59144 — confirm availability for your org/plan. Example path="/web3/1", method="POST", body={"jsonrpc":"2.0","id":1,"method":"eth_blockNumber","params":[]} Gotchas: Portfolio gateway path repeats "portfolio" (/portfolio/portfolio/v5.0/...) because the gateway strips the first segment. Spot Price returns WEI in native currency unless you set currency. Token list responses are large; prefer search. Token Details does not support native ETH pseudo-address 0xeeee...eeee; use WETH. Balance responses may include zero balances—filter client-side. For limit order flows (build, sign, create, cancel), prefer the "orderbook" tool. For swap execution, prefer the "swap" tool. Use product_api for direct REST access to any endpoint.

• swapFree

  [Requires authentication] Call the authenticate tool first to start or confirm 1inch Business login (initialize 200 is still anonymous). If authenticate or this tool returns HTTP 401, complete OAuth, then retry. Swap tokens via 1inch. Supports classic (on-chain), Fusion (intent/gasless), and cross-chain swaps. Omit preferredType and the tool picks a type for you; set preferredType (classic, fusion, crosschain) to choose explicitly. When quoteOnly returns a `recommended` type and that type is available, present **only** that type to the user. Do not mention, compare, or suggest other swap types unless the user explicitly asks to compare alternatives. ERC-20 source tokens may require a one-time approval transaction before the swap can proceed; the approval costs native gas on the source chain even for gasless Fusion/cross-chain swaps. When a response includes an `approval` block, tell the user upfront (approval.estimatedCost holds the estimated cost in native units). Usage modes: 1. **Quote** (quoteOnly=true): Returns only one swap type and its quote. If you pass `preferredType` explicitly (classic, fusion, or crosschain), the response returns that exact type (when a quote for it is available). If `preferredType` is omitted, the tool compares classic, Fusion, and cross-chain internally and picks the best one. The chosen type is echoed as `recommended`. 2. **Execute** (default): Returns data to sign. Response type depends on swap mode: - Classic → {type:"classic", step:"approve"|"swap", tx:{to,data,value}} → sign with eth_sendTransaction, wait for receipt. If step="approve", sign the approve tx first, then call swap again for the actual swap tx. - Fusion → {type:"fusion", orderHash, typedData} → sign typedData with eth_signTypedData_v4, then call this tool again with signedOrder=<signature> and orderHash. - Cross-chain → {type:"crosschain", orderHash, typedData, srcChain, dstChain} → same as Fusion: sign typedData, then submit with signedOrder. 3. **Submit** (signedOrder=<sig>): Submit a previously signed Fusion/cross-chain order. Returns {status:"submitted", orderHash}. Flows: - **Full flow**: quote first (quoteOnly=true), then execute with chosen preferredType, then sign + submit. - **Shortcut**: skip the quote — call directly without quoteOnly. Omit preferredType to let the tool pick a type, or set preferredType explicitly. Set dstChain for cross-chain. Responses that require on-chain transactions link to a guide. Use the product_api tool with path="/web3/{chainId}" to broadcast (see linked guide for body format). With an active WalletConnect session (`walletconnect` action=connect), swap execution is automatic by default: classic approve/swap txs, Fusion/cross-chain sign-and-submit, and native escrow sends are prompted in the user’s wallet — no manual broadcast or separate submit step. Set `execute=false` to receive unsigned payloads instead. Set `execute=true` to require WalletConnect (fails if not connected).

• walletconnectFree

  Pair and use an EVM and/or Solana wallet via WalletConnect v2. **No authentication required** — available to every user (including unauthenticated/anonymous). Non-custodial: the server never holds keys and the user approves every signature/transaction in their own wallet. **Pairing proposal** is controlled per request via optional `pairingTarget` on `action: "connect"`: `eth` (default, eip155 only), `solana`, or `both`. Many mobile wallets fail if eip155 and solana are proposed together; prefer `eth` or `solana` unless the user needs both in one session. **Every call must include `action`** (string). **Connect QR (critical for assistants):** On `action: "connect"`, successful responses return **(1) an MCP `type: "image"` PNG** of the pairing QR (render this even if the host has no `resources/read`), then **(2) optional `resource_link`**, then **(3) text JSON** with `pairingQrResourceUri`, `presentation`, `nextSteps`, `url`, optional `mobileDeeplinks`, etc. **Desktop / scan UX:** show the image content block first. **Mobile / no-camera:** follow `nextSteps`; when present, `mobileDeeplinks` lists HTTPS `url` (+ `nativeUrl`) per curated WalletConnect wallet. Raw `wc:` (`url` / `walletConnectLinkForUser`) remains fallback. **Avoid calling `connect` again while pairing is still in progress** unless the user must reset — pass `walletSessionToken` to resume the same pairing after MCP session rotation. **Flow:** (1) `connect` as above. (2) User approves in the wallet (EVM only, Solana only, or both). (3) `status` until `kind` is `session` — optional `evm` / `solana` blocks; `address`/`chains` remain legacy EVM when EVM is connected. (4) `sign` / `send_transaction` or swap `execute=true` (swap execute remains EVM unless extended elsewhere). `kind: "pending"` on `status` is success — keep polling. **Actions (exact JSON shapes):** - **connect** — `{ "action": "connect", "sessionTtlDays"?: number, "pairingTarget"?: "eth" | "solana" | "both", "walletSessionToken"?: string }` - **status** — `{ "action": "status" }` (anonymous sessions include a `terms` block showing the connected wallet's 1inch Terms-of-Use acceptance state) - **sign** — EVM: `personal_sign` / `eth_signTypedData_v4`. Solana: `solana_signMessage` / `solana_signTransaction` (see schema fields `params`, `chainId`, `solanaChainId`). - **send_transaction** — EVM: `tx.to`, numeric `tx.chainId`. Solana: string `tx.chainId` (`solana:...`), `tx.serializedTransaction` (base64). Set `tx.namespace` when both WC namespaces are active and the payload is ambiguous. - **accept_terms** — `{ "action": "accept_terms", "address"?: "0x…" }`. When the user has not accepted yet: **write to the user** that they must sign the 1inch Terms of Use in their wallet (one-time, gas-free personal_sign), **then immediately call this action in the same turn** so the signature prompt appears. You trigger the signing — do not only instruct them to sign. Required before anonymous aqua create_position / close_position. Idempotent — already-accepted wallets return immediately without a prompt. - **disconnect** — `{ "action": "disconnect" }` **Anonymous durable sessions:** for unauthenticated callers, pairing `connect` (QR) returns a `walletSessionToken`. Store it and pass it back as `walletSessionToken` on later `status` / `sign` / `send_transaction` / `accept_terms` / `disconnect` **and** on a later `connect` to resume the same pairing after MCP session rotation. A tokenless `connect` that resumes an already-approved session does **not** mint a new token — within this MCP session, `status` / `sign` still work via `anon:{sessionId}`. Authenticated callers ignore the token (their WC session is scoped by org/app). Non-custodial relay; no authentication required.
