Common questions

Is Recon Crypto MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: RPC_API_KEY, ETHERSCAN_API_KEY, ONEINCH_API_KEY, WALLETCONNECT_PROJECT_ID

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.3.1) reached the registry 7 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

VaultPilot MCP

Self-custodial DeFi for AI agents. The agent proposes, you approve on your Ledger — designed for the threat model where the agent, MCP, and host can all be compromised. Only the device is trusted; private keys never leave it.

Read on-chain positions and prepare transactions across Ethereum, Arbitrum, Polygon, Base, Optimism, TRON, Solana, Bitcoin, and Litecoin. Supported protocols: Aave V3, Compound V3, Morpho Blue, Uniswap V3 (swap + LP verbs), Curve, Lido, EigenLayer, Rocket Pool, Safe (Gnosis) multisig on EVM, MarginFi, Kamino, Marinade, Jito on Solana, SunSwap on TRON, plus LiFi (EVM + EVM↔Solana + TRON + BTC swap/bridge) and Jupiter v6 (Solana swap), with 1inch as an optional EVM quote cross-check. EVM signs over WalletConnect → Ledger Live; TRON, Solana, Bitcoin and Litecoin sign over USB HID directly to the device (Ledger Live's WalletConnect bridge does not support those namespaces today). Works with Claude Code (CLI/terminal), Cursor, and any MCP-compatible client over stdio. Claude.ai chat (web + native desktop app) needs a hosted MCP endpoint — on the roadmap, not yet shipped.

Agents: read [AGENTS.md](./AGENTS.md). One-line prompt to paste into Claude Code / Cursor / any MCP-capable agent:

Features

Portfolio — cross-chain balances, DeFi position aggregation, USD totals, NFT collections (EVM + Solana via Helius DAS), wallet-level PnL (mtd / ytd / 30d / 7d / 1d), daily briefing
Positions — Aave, Compound, Morpho, Uniswap V3 LP, Curve, MarginFi, Kamino, Safe (Gnosis) multisig; multi-protocol health-factor alerts; liquidation-risk simulation
Staking — Lido (stake / unstake / stETH↔wstETH wrap) + EigenLayer + Rocket Pool (EVM); TRON Stake 2.0 (freeze / unfreeze / vote / claim); Solana (Marinade, Jito, native delegate/deactivate/withdraw)
Swaps + bridges — LiFi (EVM + EVM↔Solana + TRON + BTC routes, optional 1inch cross-check), Jupiter v6 (Solana), direct Uniswap V3, Curve, SunSwap (TRON)
Execution — prepare/sign for every supported protocol + native/token sends, ERC-20 approvals + revoke, WETH wrap/unwrap, prepare_custom_call escape hatch for arbitrary verified-contract calls. Solana sends use a per-wallet durable-nonce account so Ledger review doesn't race the ~60s blockhash window; every Solana prepare runs a simulateTransaction gate so program-level reverts fail at prepare time, not on broadcast.
Bitcoin + Litecoin — native segwit + taproot sends, BIP-125 RBF fee-bumps, PSBT multisig (combine / sign / finalize), BIP-137 message signing, mempool.space fee estimation, optional Bitcoin Core / Litecoin Core RPC for forensic chain reads (forks, mempool census, fee percentiles)
Security — contract verification, upgradeability checks, privileged-role enumeration, DefiLlama-backed risk score, on-device Ledger attestation + firmware version pin, verify_tx_decode for second-LLM bytes-vs-intent cross-check, signed on-disk contacts/address-book
Utilities — ENS resolution, symbol→contract resolve_token registry, token balances, allowance enumeration, tx status, explain_tx post-hoc decode, compare_yields across lending + LST adapters
Demo mode — curated personas (whale / defi-degen / stable-saver / staking-maxi) for first contact with no RPC keys / Ledger / config file

Security model

Compromise model: the AI agent, MCP server, and host computer can all be attacker-controlled. Only the Ledger is trusted. Every transaction is cryptographically bound across each layer so tampering — a swapped recipient, a rewritten swap route, a smuggled approval — is tamper-evident on the device screen before signing.

user-intent ──► agent ──► MCP server ──► WalletConnect / USB-HID ──► Ledger Live / host ──► Ledger device

Defense in depth: server-side prepare↔send fingerprint, independent 4byte.directory selector check, agent-side ABI decode + pre-sign hash recompute, on-device clear-sign or blind-sign-hash match, WalletConnect session-topic cross-check, previewToken/userDecision gate, and get_verification_artifact for second-LLM cross-verification on high-value flows. See [SECURITY.md](./docs/SECURITY.md) for the full threat model, defenses table, residual risks, and verification recipes.

Agent-side hardening (strongly recommended)

The MCP's own CHECKS PERFORMED directives can be silently omitted by a compromised server. Install the companion vaultpilot-security-skill so the agent enforces cryptographic-integrity invariants regardless of what the MCP says — bytes decode, dispatch-target allowlist, hash recompute, chain-must-be-explicit, bridge-recipient cross-check, approval-class surfacing, always-optional second-LLM offer surfaced on every preview, set-level intent verification, durable-binding source-of-truth:

git clone https://github.com/szhygulin/vaultpilot-security-skill.git \

~/.claude/skills/vaultpilot-preflight

Restart Claude Code. The skill file's SHA-256 is pinned in the server source; on-disk tamper or plugin collision surfaces as integrity check FAILED.

Conversational `/setup` (optional)

For chat-driven onboarding that detects current config and only collects keys you actually need, install the companion vaultpilot-setup-skill:

git clone https://github.com/szhygulin/vaultpilot-setup-skill.git \

~/.claude/skills/vaultpilot-setup

Restart, then type /setup.

Supported chains

EVM — Ethereum, Arbitrum, Polygon, Base, Optimism. Lido reads on Ethereum + Arbitrum, Lido writes Ethereum-only. EigenLayer + Morpho Blue + Rocket Pool Ethereum-only. Compound V3 + Aave V3 + Uniswap V3 + LiFi + Safe multisig span all five chains; per-protocol address coverage varies — readers short-circuit cleanly where a protocol isn't deployed.

TRON — TRX + canonical TRC-20 stablecoins (USDT, USDC, USDD, TUSD); Stake 2.0 freeze/unfreeze/withdraw-expire-unfreeze + voting-reward claims; SunSwap (same-chain TRX↔TRC-20 swaps); LiFi-routed TRON↔EVM bridging. No lending/LP (Aave/Compound/Morpho/Uniswap aren't deployed). Pair once per session via pair_ledger_tron.

Solana — SOL + SPL balances, MarginFi + Kamino lending, Marinade / Jito / native stake-account reads with SOL-equivalent valuation, Jupiter v6 quotes, Helius DAS NFT portfolio. Writes cover SOL/SPL transfers, MarginFi + Kamino supply/withdraw/borrow/repay, Jupiter swaps, Marinade stake + immediate-unstake, Jito stake-pool deposit, native SOL delegate/deactivate/withdraw, and LiFi-routed EVM↔Solana bridging. Per-wallet durable-nonce account (~0.00144 SOL rent, reclaimable) protects sends from blockhash expiry during Ledger review (prepare_solana_nonce_init / _close). SPL / MarginFi / Kamino / Jupiter / Jito blind-sign against a Message Hash — enable Allow blind signing in the Solana app's Settings; SOL native transfers clear-sign. Pair once per session via pair_ledger_solana.

Bitcoin + Litecoin — balance, UTXO, fee-estimate, and tx-history readers via Esplora (mempool.space / litecoinspace.org). Native segwit + taproot sends, BIP-125 RBF fee-bumps, multisig PSBT (combine / sign / finalize), BIP-137 message signing, LiFi-routed BTC→EVM/Solana swaps. Optional Bitcoin Core / Litecoin Core JSON-RPC unlocks forensic tools that Esplora cannot serve (chain tips, block stats, mempool summary) — see INSTALL.md §9 for setup. Pair once via pair_ledger_btc / pair_ledger_ltc.

Ledger Live's WalletConnect bridge does not honor the tron: namespace (verified 2026-04-14) or expose Solana accounts (verified 2026-04-23) or expose BTC/LTC namespaces, which is why those paths use USB HID. Readers short-circuit cleanly on chains where a protocol isn't deployed.

get_transaction_status — poll inclusion by hash
explain_tx — post-hoc decode of a historical tx

Diagnostics:

get_solana_setup_status — probe nonce + MarginFi account PDAs
get_vaultpilot_config_status — local config diagnostic (RPC sources, key presence, paired-account counts, WC topic suffix, skill state). Booleans / counts only — no secret values.
get_ledger_device_info, get_ledger_status, verify_ledger_attestation / _firmware / _live_codesign — device + session discovery, on-device attestation, firmware-version pin
