できること

ツールの名前と説明は、サーバーが2026年11月7日に返したそのままの内容です。書いたのは作者で、私たちではありません。プレーンテキストとして表示しています。

  • read_account_info

    Get full overview of an Arcadia account: health factor, collateral value, debt, deposited assets, liquidation price, and automation status. Health factor = 1 - (used_margin / liquidation_value): 1 = no debt (safest), >0 = healthy, 0 = liquidation threshold, <0 = past liquidation.

  • read_account_history

    Get an Arcadia account's historical net value over time. Returns a time series of snapshots, oldest first, each `{ timestamp, net_value }` — `timestamp` is unix seconds and `net_value` is USD (human-readable, not raw units). Useful for charting account performance over a period.

  • read_account_pnl

    Get PnL (cost basis) and yield earned for an Arcadia account. Returns lifetime totals: cost basis vs current value (negative cost_basis = net profit withdrawn), net transfers per token, total yield earned in USD and per token. cost_basis, current_value, cost_diff are in USD (huma

  • read_pool_list

    List all Arcadia lending pools: TVL, utilization, available liquidity. Key fields: interest_rate = current borrow cost, lending_apy = lender yield. All rates are decimal fractions (1.0 = 100%, 0.06 = 6%). For APY history on a specific pool, use read_pool_info.

  • read_pool_info

    Get detailed info for a single lending pool including APY history over time. Useful for analyzing rate trends and comparing pools. Use read_pool_list to discover pool addresses.

  • read_asset_list

    List supported collateral assets on Arcadia. Returns compact list (address, symbol, decimals, type). Use search to filter by symbol substring. For USD prices, use read_asset_prices.

  • read_asset_prices

    Get USD prices for one or more asset addresses. Pass a single address or comma-separated addresses. Returns a price map keyed by address.

  • read_strategy_list

    Get Arcadia LP strategies. Use featured_only=true for curated top strategies (recommended first call). Returns a paginated list with 7d avg APY for each strategy's default range. Increase limit or use offset for pagination. All APY values are decimal fractions (1.0 = 100%, 0.05 =

  • read_strategy_info

    Get full detail for a specific LP strategy by ID: includes APY per range width (narrower range = higher APY but more rebalancing cost/risk), pool info, and configuration. Use read_strategy_list to discover strategy IDs. All APY values are decimal fractions (1.0 = 100%, 0.05 = 5%)

  • read_strategy_recommendation

    Get a rebalancing recommendation for an Arcadia account: suggests asset changes to optimize yield. Uses 1d APY (not 7d like read_strategy_list), so recommended strategies may differ from the list ranking. APY values are decimal fractions (0.05 = 5%). weekly_earning_difference is

  • read_point_leaderboard

    Get the Arcadia points leaderboard (paginated). For a specific wallet's points balance, use read_wallet_points.

  • read_guides

    Get Arcadia workflow guides and reference documentation. Call this before multi-step workflows (opening LP positions, enabling automation, closing positions) or when you need contract addresses, asset manager addresses, or strategy parameters. Topics: overview (addresses + tool c

  • read_wallet_balances

    Get native ETH and ERC20 token balances for a wallet address. Reads directly from chain via RPC multicall. Use before write_account_add_liquidity or write_account_deposit to verify the wallet has sufficient tokens. Returns both raw balance (smallest unit/wei) and formatted (human

  • read_wallet_allowances

    Check ERC20 token allowances for a spender address. Use before write_wallet_approve to avoid redundant approvals: skip approving if the current allowance is already sufficient.

  • read_wallet_accounts

    List all Arcadia accounts owned by a wallet address. Returns a summary of each account (address, name). Call read_account_info with a specific account_address for full details like health factor, collateral, and debt.

  • read_wallet_points

    Get Arcadia points balance for a specific wallet address.

  • read_asset_manager_intents

    List the automation intents Arcadia supports, with the parameters each one accepts. Pass account_address to also get per-account availability: which intents can be enabled right now and, for any that cannot, the compatibility rule blocking it. Pass position_id as well to scope av

  • read_asset_manager_current

    Read which asset managers are currently enabled on an account, with their decoded on-chain configuration. Returns the active managers (address, protocol, initiator, decoded strategy metadata, slippage and value-loss caps, fee recipient), the intents they map to, and Merkl claim s

  • read_account_aero_upgrade

    Which Arcadia accounts have something to upgrade to Aero (MetadexCL V1): Slipstream V1 to V3 positions (Aerodrome on Base, Velodrome on Optimism, staked or not) and old AERO. Pass wallet_address for every account of a wallet, or account_address for one. Per account: status (ready

  • write_account_create

    Build an unsigned transaction to create a new Arcadia account via the Factory contract. account_version: 3 with creditor → V3 margin account (can borrow/leverage). account_version: 0 or 4 → V4 spot account (no borrowing, creditor is ignored, any ERC20 allowed). Returns the predic

  • write_account_deposit

    Build an unsigned transaction to deposit assets into an Arcadia account as collateral. Supports ERC20 tokens and ERC721 NFTs (LP positions). NOT needed before write_account_add_liquidity: that tool deposits from wallet atomically. Ensure the account is approved first (call read_w

  • write_account_withdraw

    Build an unsigned transaction to withdraw assets from an Arcadia account to the owner's wallet. Only the account owner can withdraw. Will revert if the account has debt and withdrawal would make it undercollateralized. Does not support max_uint256: pass exact amounts from read_ac

  • write_account_borrow

    Build an unsigned transaction to borrow from an Arcadia lending pool against account collateral. NOT needed for leveraged LP: write_account_add_liquidity handles borrowing internally when leverage > 0. Only works with margin accounts (created with a creditor/lending pool). Spot a

  • write_account_repay

    Repay debt to an Arcadia lending pool using tokens from the wallet (requires ERC20 allowance). To repay using account collateral instead (no wallet tokens needed), use write_account_deleverage. Check allowance first (read_wallet_allowances), then approve the pool if needed (write

  • write_account_add_liquidity

    Multi-step flash-action: atomically combines [deposit from wallet] + [use account collateral] + [swap to optimal ratio] + [mint LP] + [borrow if leveraged] in ONE transaction. Do NOT call write_account_deposit separately. Capital sources: wallet tokens (deposits array), existing

  • write_account_remove_liquidity

    Flash-action: PARTIALLY decreases liquidity from an LP position. The position remains open with reduced liquidity; underlying tokens stay in the account. For FULL position exit (burn LP + swap + repay + withdraw), use write_account_close instead: it batches everything into one at

  • write_account_swap

    Flash-action: swaps assets within an Arcadia account in one atomic transaction. The backend finds the optimal swap route. NOTE: If you are closing a position (swap + repay + withdraw), prefer write_account_close which batches everything atomically. Only use this tool for standalo

  • write_account_deleverage

    Multi-step flash-action: sells account collateral to the debt token and repays in one atomic transaction: no wallet tokens needed. To repay from wallet tokens instead, use write_account_repay. NOTE: If you are closing a position (remove LP + swap + repay + withdraw), prefer write

  • write_account_stake

    Flash-action: stake, unstake, or claim rewards for an LP position in one atomic transaction. Use the `action` parameter to select the operation. `asset_address` is the position manager contract: pass the non-staked PM address when staking, or the staked PM address when unstaking.

  • write_account_close

    Atomic flash-action that closes an Arcadia account position in ONE transaction. Combines up to 3 steps atomically: [burn LP position] + [swap all tokens to a single target asset] + [repay debt]. Tokens remain in the account after closing: use write_account_withdraw to send them t

  • write_account_aero_upgrade

    Upgrade one Arcadia account to Aero (MetadexCL V1) in one flashAction: every Slipstream V1/V2/V3 position (dex_protocol slipstream*, staked or not, see read_account_info) moves to the Aero CL pool with the same pair and variant at the same range and tick spacing (when Aero has no

  • write_wallet_approve

    Build an unsigned approval transaction. For ERC20 tokens: generates approve(spender, amount). For ERC721/ERC1155 NFTs (e.g. LP positions): generates setApprovalForAll(operator, true). Required before write_account_deposit or write_account_add_liquidity (when depositing from walle

  • write_wallet_upgrade_velo

    Upgrade VELO held in a wallet on Optimism to the new AERO on Base: ordered unsigned wallet transactions from owner_address, an approve when the allowance is short, then depositLiquid on the Velodrome migration with the Hyperlane fee as value. 0.044 new AERO per VELO arrives at th

  • write_pool_deposit

    Build an unsigned deposit transaction into an Arcadia lending tranche (ERC-4626). Lenders deposit the pool's underlying asset (USDC/WETH/cbBTC) and receive tranche shares that accrue interest from borrowers. Requires prior ERC-20 approval to the tranche (see write_wallet_approve)

  • write_pool_redeem

    Build an unsigned redeem transaction to withdraw from an Arcadia lending tranche (ERC-4626). Burns tranche shares and returns the corresponding amount of underlying asset, including accrued interest. The owner must be the shares holder; receiver is where the underlying asset is s

  • write_account_automations

    Configure an account's automations from a list of intents and return the unsigned setAssetManagers transaction. The backend resolves which asset managers each intent needs, validates that the combination is compatible, encodes the metadata and builds the calldata, so you describe

  • write_account_automations_delta

    Apply an explicit change to an account's automations and return the unsigned setAssetManagers transaction. Unlike write_account_automations this is a delta, not a full desired state: automations you do not mention are left untouched. Use it to switch one automation on or off with

  • dev_send

    DEV ONLY: Sign and broadcast an unsigned transaction using a local private key (PK env var). For production, use a dedicated wallet MCP server (Fireblocks, Safe, Turnkey, etc.) instead of this tool. Takes the transaction object returned by any write_* tool and submits it onchain.

Dev Tools

Always registered but requires PK env var to function.

ToolDescription
dev_sendSign and broadcast an unsigned transaction using a local private key (PK env var). Not for production: use a dedicated wallet MCP server instead.

Transaction Signing

All write tools return unsigned transactions as { to, data, value, chainId }. This server does NOT sign or broadcast — your agent or application is responsible for that.

Options

Wallet MCP servers (recommended for production): Pair this server with a wallet MCP server that handles signing:

Wallet MCPProviderModel
MCP Wallet SignerCommunityNon-custodial, routes to browser wallet (MetaMask, Rabby)
Coinbase AgentKitCoinbaseWallet-agnostic, supports multiple providers
Phantom MCPPhantomEmbedded wallet
Privy MCPPrivyWallet infrastructure
Safe MCPCommunityMulti-sig via Safe

Or use your existing wallet setup (Fireblocks, Dfns, Turnkey, Biconomy, Dynamic) and pass the unsigned tx object to your provider's signing method.

viem/ethers in your agent:

import { createWalletClient, http } from "viem";

import { privateKeyToAccount } from "viem/accounts"; import { base } from "viem/chains";

const account = privateKeyToAccount("0x..."); const client = createWalletClient({ account, chain: base, transport: http() });

// tx = result from any write_* tool const hash = await client.sendTransaction(tx);

Built-in `dev_send` tool (development only): The server includes a dev-only signing tool that reads a private key from the PK environment variable. Set PK via a .env file or your MCP client config:

# .env in the server directory (never commit — already gitignored)

PK=0xYourPrivateKeyHex RPC_URL_BASE=https://base-mainnet.g.alchemy.com/v2/your-key

The server loads .env automatically on startup. Works with any MCP client (Claude Desktop, Claude Code, VSCode, Cursor). MCP client env block settings take precedence if both are set.

Not for production — use a dedicated wallet MCP server (Fireblocks, Turnkey, Safe) instead.
