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.

Do not mention, compare, or suggest other swap types unless the user explicitly asks to compare alternatives.\n\nERC-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).\n\nUsage modes:\n1. **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`.\n2. **Execute** (default): Returns data to sign. Response type depends on swap mode:\n   - 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.\n   - Fusion → {type:\"fusion\", orderHash, typedData} → sign typedData with eth_signTypedData_v4, then call this tool again with signedOrder=<signature> and orderHash.\n   - Cross-chain → {type:\"crosschain\", orderHash, typedData, srcChain, dstChain} → same as Fusion: sign typedData, then submit with signedOrder.\n3. **Submit** (signedOrder=<sig>): Submit a previously signed Fusion/cross-chain order. Returns {status:\"submitted\", orderHash}.\n\nFlows:\n- **Full flow**: quote first (quoteOnly=true), then execute with chosen preferredType, then sign + submit.\n- **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.\n\nResponses 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).\n\nWith 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.

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).…"}],"inputs":{"probes":[{"url":"https://api.1inch.com/mcp/protocol","reachable":true,"authRequired":false,"latencyMs":709,"serverInfo":{"name":"1inch-business","version":"1.0.0"}}],"packages":[],"repo":{"found":true,"owner":"1inch","repo":"1inch-ai","archived":false,"pushedAt":"2026-09-13T18:48:36Z","stars":2,"forks":0,"openIssues":0,"ownerType":"Organization","ownerAvatarUrl":"https://avatars.githubusercontent.com/u/43341157?v=4","ownerCreatedAt":"2018-09-17T11:52:17Z","license":"MIT"},"icon":{"url":"https://business.1inch.com/portal/favicon/favicon-128x128.png","source":"registry","width":128,"height":128},"presence":{"stars":2,"forks":0,"downloadsWeek":null,"license":"MIT","lastPushAt":"2026-09-13T18:48:36.000Z","score":28}}}},"grade_history":[],"reviews":[]}
