"instructions": "1inch Business MCP Server — provides SDK examples and documentation search.\n\n## SDK Examples\nFor code implementations, use list_examples + get_example:\n- Intent/Fusion swaps: \"@1inch-examples/intent-swap\" (EVM: src/evm/, Solana: src/solana/)\n- Limit orders: \"@1inch-examples/limit-order\"\n- Cross-chain swaps: \"@1inch-examples/cross-chain-swap\"\n\n## Documentation Search\nUse search for API endpoint details not covered by examples. Always prefer example code over documentation snippets.\n\n## Authentication\nInitialize HTTP 200 is **not** login — that is the mcp-free / anonymous identity. Public tools work without a real org. Paid tools need a real organization (OAuth or API key), not mcp-free.\nAll tools are always listed so you know they exist. Some require OAuth to run:\n- **Public (no auth):** search, list_examples, get_example, aqua (analytics actions need nothing — write actions need a WalletConnect-verified wallet that signed the 1inch Terms of Use).\n- **Public (no auth), when enabled:** walletconnect — non-custodial wallet pairing/signing available to every user, including unauthenticated.\n- **Requires OAuth:** authenticate, swap, orderbook, product_api (and debug when enabled).\n**Before** paid tools, call `authenticate`. If the host returns HTTP 401, complete OAuth (`mcp_auth` / connect this server), then call `authenticate` again until it returns `{ authenticated: true, ... }`. Do not treat a PaymentRequired / x402 tool result as login. Do not skip `authenticate` because initialize succeeded.\n\n## Swap Workflow\nUse the \"swap\" tool to execute token swaps (requires authentication). Two approaches:\n- **Shortcut**: Call swap directly (omit quoteOnly). Omit preferredType to let the tool pick a type, or set preferredType (classic, fusion, crosschain) to choose explicitly. Set dstChain for cross-chain.\n- **Full flow**: Call swap with quoteOnly=true to compare quotes and receive a recommended type, then execute with the chosen preferredType.\n\nThe response includes a nextSteps array — follow those instructions to complete the swap:\n- Classic: sign the tx with eth_sendTransaction, wait for receipt. If an approve step is returned, sign that first, then call swap again.\n- Fusion/cross-chain: sign the typedData with eth_signTypedData_v4, then call swap again with signedOrder and orderHash to submit.\n\n## Limit orders (Orderbook)\nUse the \"orderbook\" tool (requires authentication) for limit orders. Recommended flow:\n1. **build**: Provide maker/taker assets, amounts, maker address → server builds order, returns EIP-712 typedData to sign.\n2. **create**: After signing typedData, submit with orderHash + signature + orderData.\nAlso supports list (query orders) and cancel (on-chain cancellation guidance). No SDK needed on the client.\n\n## Product API\nUse the \"product_api\" tool to call any 1inch product API endpoint (Portfolio, Orderbook, Spot Price, Token, Gas Price, etc.) with the user's OAuth credentials. Requires authentication — call authenticate first; initialize 200 is still anonymous.\n\n## Aqua positions\nUse the \"aqua\" tool for 1inch Aqua positions (shared-liquidity market making). Analytics actions are read-only and need no OAuth. Write actions (non-custodial — the user's wallet signs): create_position (preview first, then confirmed:true), close_position. Without OAuth they require a connected WalletConnect wallet that passed screening and signed the 1inch Terms of Use. When tos_acceptance_required: write to the user that they must sign, then immediately call walletconnect accept_terms in the same turn (you trigger the signing). Pass walletSessionToken on those writes after MCP session rotation. create_position refuses to approve when the wallet cannot fund the legs (insufficient_funds). build_swap is B2B-only. Read the resource file://1inch-mcp/guides/aqua-workflow for examples and maker flows.\n\n## WalletConnect\nUse the \"walletconnect\" tool to pair with the user's EVM and/or Solana wallet for signatures and transactions. No authentication is required — it is non-custodial and the user approves every request in their own wallet. Unauthenticated callers should persist the `walletSessionToken` returned by `connect` and pass it back on later calls to keep the session across MCP session rotation. For swap and orderbook, optional execute=true can submit or sign in one step when a WalletConnect session is active.",

"description": "[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.\n\nWhen 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.\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. Set `execute=false` to receive unsigned payloads instead. Set `execute=true` to require WalletConnect (fails if not connected).",

"description": "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).\n\n**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.\n\n**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.\n\n**Actions (exact JSON shapes):**\n- **connect** — `{ \"action\": \"connect\", \"sessionTtlDays\"?: number, \"pairingTarget\"?: \"eth\" | \"solana\" | \"both\", \"walletSessionToken\"?: string }`\n- **status** — `{ \"action\": \"status\" }` (anonymous sessions include a `terms` block showing the connected wallet's 1inch Terms-of-Use acceptance state)\n- **sign** — EVM: `personal_sign` / `eth_signTypedData_v4`. Solana: `solana_signMessage` / `solana_signTransaction` (see schema fields `params`, `chainId`, `solanaChainId`).\n- **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.\n- **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.\n- **disconnect** — `{ \"action\": \"disconnect\" }`\n\n**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).\n\nNon-custodial relay; no authentication required.",
