Recon Crypto MCP server

Read from the package source without running it. The installed server may list more.

• check_contract_security

  Check Etherscan verification status, EIP-1967 proxy pattern, implementation/admin slots, and the presence of dangerous admin functions (mint, pause, upgradeTo, etc.) for a given contract.

• check_permission_risks

  Enumerate privileged roles on a contract (Ownable.owner, AccessControl hints) and classify holders as EOA, Gnosis Safe multisig, or TimelockController.

• estimate_staking_yield

  Project annual yield on a hypothetical staking amount for a given protocol (Lido or EigenLayer) using current APRs.

• get_compound_positions

  Fetch Compound V3 (Comet) positions for a wallet across supported markets (cUSDCv3, cUSDTv3, cWETHv3, etc.). Returns base-token supplied/borrowed, per-asset collateral, and USD totals.

• get_health_alerts

  Check for Aave V3 lending positions approaching liquidation. Returns positions whose health factor is below the given threshold (default 1.5).

• get_ledger_status

  Report whether a WalletConnect session with Ledger Live is active, which wallet it's connected to, and which accounts are exposed.

• get_lending_positions

  Fetch all Aave V3 lending/borrowing positions for a wallet. Returns collateral, debt (both in USD and per-asset), health factor, LTV, and liquidation threshold across Ethereum and Arbitrum.

• get_lp_positions

  Fetch all Uniswap V3 liquidity-provider positions for a wallet. Returns token pair, current token amounts, fee tier, in-range status, uncollected fees (lower bound), and an approximate impermanent-loss estimate.

• get_morpho_positions

  Fetch Morpho Blue positions for a wallet. If `marketIds` is omitted, the server auto-discovers the wallet's markets by scanning Morpho Blue event logs (may take several seconds on a cold call). Pass explicit `marketIds` (bytes32 each, keccak256 of MarketParams) as a fast path. Returns per-market supplied/borrowed assets and collateral.

• get_portfolio_summary

  Aggregate a complete portfolio view: native balances, top ERC-20 holdings, Aave V3 positions, Uniswap V3 LP positions, and staking — with USD totals and per-chain breakdown.

• get_protocol_risk_score

  Return a 0-100 risk score for a DeFi protocol, combining TVL size, 30-day TVL trend, contract age, audit count (DefiLlama), and Immunefi bug-bounty status. Higher = safer.

• get_staking_positions

  Fetch Lido (stETH/wstETH) and EigenLayer staking positions for a wallet across supported chains. Returns per-protocol staked amounts, USD value, APR, and EigenLayer delegation target.

• get_staking_rewards

  Estimate staking rewards earned over a given period (7d/30d/90d/1y) using the current APR as a proxy. This is an estimate, not an on-chain rewards query.

• get_swap_quote

  Get a LiFi aggregator quote for a token swap (same-chain) or bridge (cross-chain). Returns expected output, fees, execution time, and the underlying tool selected. No transaction is built.

• get_token_balance

  Fetch a wallet's balance of any ERC-20 token or the chain's native coin. Pass `token: "native"` for ETH (or chain-native asset) or an ERC-20 contract address. Returns amount, decimals, symbol, and USD value.

• get_token_price

  Fetch the USD price of a token via DefiLlama. Pass `token: "native"` for the chain's native asset (ETH on ethereum/arbitrum, MATIC on polygon) or an ERC-20 contract address. Prefer this over get_swap_quote for pure price lookups — no wallet or liquidity simulation needed.

• get_transaction_status

  Poll a transaction's status via the chain's RPC. Returns pending / success / failed, or unknown if the node hasn't seen it yet.

• pair_ledger_live

  Initiate a WalletConnect v2 pairing session with Ledger Live. Returns a URI and ASCII QR code — paste into Ledger Live's WalletConnect screen to complete pairing. The session persists for future transactions.

• prepare_aave_borrow

  Build an unsigned Aave V3 borrow transaction (variable rate — stable rate is deprecated and reverts on production markets). The borrower must already have sufficient collateral supplied.

• prepare_aave_repay

  Build an unsigned Aave V3 repay transaction. If an ERC-20 approve() is required first, it is returned as the outer tx and repay is in `.next`. Pass `amount: "max"` to repay the full debt.

• prepare_aave_supply

  Build an unsigned Aave V3 supply transaction. If an ERC-20 approve() is required first, it is returned as the outer tx and the supply tx is embedded in `.next`. Both must be signed for the supply to succeed.

• prepare_aave_withdraw

  Build an unsigned Aave V3 withdraw transaction. Pass `amount: "max"` to withdraw the entire aToken balance.

• prepare_compound_borrow

  Build an unsigned Compound V3 borrow transaction — encoded as withdraw(baseToken) beyond the user's supplied balance. Base token is resolved on-chain from the Comet.

• prepare_compound_repay

  Build an unsigned Compound V3 repay transaction — encoded as supply(baseToken) against an outstanding borrow. Includes an approve step if needed. Pass `amount: "max"` for a full repay.

• prepare_compound_supply

  Build an unsigned Compound V3 supply transaction (base token or collateral). If an ERC-20 approve() is required first, it is returned as the outer tx with supply in `.next`.

• prepare_compound_withdraw

  Build an unsigned Compound V3 withdraw transaction. Pass `amount: "max"` to withdraw the full supplied balance.

• prepare_eigenlayer_deposit

  Build an unsigned EigenLayer StrategyManager.depositIntoStrategy transaction. Includes an ERC-20 approve step if needed.

• prepare_lido_stake

  Build an unsigned Lido stake transaction (wraps ETH into stETH via stETH.submit). The tx's value field is the ETH amount to stake.

• prepare_lido_unstake

  Build an unsigned Lido withdrawal request transaction. Wraps `requestWithdrawals` on the Lido Withdrawal Queue and includes an approve step if needed.

• prepare_morpho_borrow

  Build an unsigned Morpho Blue borrow transaction. Requires pre-existing collateral in the market.

• prepare_morpho_repay

  Build an unsigned Morpho Blue repay transaction. Includes an approve step if needed. Explicit amount only — "max" is not supported.

• prepare_morpho_supply

  Build an unsigned Morpho Blue supply transaction (deposits loan token for yield). Market params are resolved on-chain from the market id. Includes an approve step if needed.

• prepare_morpho_supply_collateral

  Build an unsigned Morpho Blue supplyCollateral transaction — adds collateral to a market. Includes an approve step if needed.

• prepare_morpho_withdraw

  Build an unsigned Morpho Blue withdraw transaction (withdraws supplied loan token). Explicit amount only — "max" is not supported; query your position first.

• prepare_morpho_withdraw_collateral

  Build an unsigned Morpho Blue withdrawCollateral transaction — removes collateral from a market. Explicit amount only.

• prepare_native_sendwrite action

  Build an unsigned native-coin send transaction (ETH on Ethereum/Arbitrum). Pass a human-readable amount like "0.5".

• prepare_swap

  Prepare an unsigned swap or bridge transaction via LiFi aggregator. Same-chain swaps use the best DEX route; cross-chain swaps use a bridge + DEX combo. The returned tx can be sent via `send_transaction`.

• prepare_token_sendwrite action

  Build an unsigned ERC-20 transfer transaction. Pass `amount: "max"` to send the full balance (resolved at build time).

• request_capability

  File a capability request against the recon-crypto-mcp GitHub repository when the user asks for something this server cannot do

• resolve_ens_name

  Resolve an ENS name (e.g. vitalik.eth) to an Ethereum address via mainnet ENS resolver. Returns null if unregistered.

• reverse_resolve_ens

  Reverse-resolve an Ethereum address to its primary ENS name. Returns null if no primary name is set.

• send_transactionwrite action

  Forward an already-prepared transaction to Ledger Live via WalletConnect for user signing. The user must review and approve the tx in Ledger Live and on their Ledger device; this call blocks until the user signs or rejects.

• simulate_position_change

  Simulate the effect of adding or removing collateral, or borrowing/repaying debt on an Aave V3 position. Returns the projected health factor and collateral/debt totals. No transaction is sent.

• simulate_transactionwrite action

  Run an eth_call against the chain's RPC to simulate a transaction without signing or broadcasting it.
