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.

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 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.
