  • build_buy_xstock_txwrite action

    Build (do NOT send) an unsigned Solana transaction that swaps USDC for a Backed xStock via Jupiter. Returns base64 versioned tx + sign URL. SERVICE only — user signs in their wallet.

  • build_deposit_yield_tx

    Build (do NOT send) an unsigned Solana transaction that swaps USDC for a yield-bearing tokenized treasury (USDY for non-US users). Returns base64 versioned tx + a one-click sign URL. SERVICE only — user signs in their wallet.

  • build_sell_xstock_tx

    Build (do NOT send) an unsigned Solana transaction that sells a Backed xStock back to USDC via Jupiter. Returns base64 versioned tx + sign URL. SERVICE only.

  • build_withdraw_yield_tx

    Build (do NOT send) an unsigned Solana transaction that swaps a yield-bearing token (e.g. USDY) back to USDC via Jupiter. Returns base64 versioned tx + sign URL.

  • check_xstock_safety

    Pre-trade SAFETY check for a tokenized US stock — verify it's the REAL token (not a copycat) and OK to buy right now, BEFORE building a buy tx. Works for any issuer (Backed/xStocks, Ondo, Remora) and any Solana mint or EVM address. Pass `ticker` (e.g. NVDA → checks the canonical xStock) OR `token` (a symbol like AAPLx / AAPLon, or a raw mint/0x address) → returns decision (ok/review/avoid), issuer

  • compare_yields

    Rank USDC lending + tokenized-treasury yields across major chains (Solana, Ethereum, Base, Arbitrum) via DefiLlama, RISK-ADJUSTED. Results are ranked by riskAdjustedApy (not headline APY): each pool's APY is discounted by volatility (sigma), TVL depth, protocol risk, DefiLlama's stability prediction, reward-emission dependence, and IL exposure. Each entry includes riskScore (0-100), riskFactors br

  • export_history

    Errand tool: export a wallet's tokenized-equity + yield-token TRADE HISTORY (a record for the user's accountant — NOT tax advice / not a tax calculation). Reconstructs USDC↔xStock and USDC↔yield-token swaps from on-chain history; execution price is derived from each tx's own balance deltas (no external price feed). Returns structured trades (date, buy/sell, asset, amount, USDC, price, Solscan link

  • get_portfolio

    Snapshot a Solana wallet: SOL, USDC, every held xStock or yield token priced via Jupiter. Returns total USD value. Read-only.

  • list_xstocks

    List supported tokenized US equities (Backed xStocks). 16 tickers across mega-cap-tech (NVDA/AAPL/TSLA/MSFT/GOOGL/AMZN/META), crypto-equity (COIN/MSTR/HOOD/CRCL), broad-market-etf (SPY/QQQ), commodity-etf (GLD), consumer (MCD), ai-defense (PLTR). Includes live Jupiter liquidity + USD price. For non-US holders only.

  • list_yield_tokens

    List supported tokenized treasury / yield-bearing tokens (USDY by Ondo Finance, more coming). These are SEC-registered securities under non-US prospectus, NOT stablecoins — unaffected by GENIUS/CLARITY Acts that ban stablecoin-issuer interest. Each share appreciates as interest accrues.

  • portfolio_health

    Stateless 'should I do anything?' check for a wallet — the periodic re-engagement tool. Returns holdings (via get_portfolio), compares held yield to the best RISK-ADJUSTED executable yield available right now, and for each held xStock computes its live premium/discount vs the underlying + an entry/exit timing signal (from accumulated microstructure data). Emits actionable `notes` the AI should sur

  • quote_tokenized_stock

    Live Jupiter quote for buying a Backed xStock with USDC on Solana. Returns expected output, price impact, route, AND a best-entry timing signal (live premium vs the underlying NYSE price, z-scored against a same-market-regime trailing baseline: good-entry / fair / rich-wait). Surface the timing note to the user. READ ONLY — no on-chain action.

  • suggest_rebalance

    Discipline tool: given a TARGET allocation, compute the trades that move a wallet toward it. READ-ONLY — it suggests buy/sell USD amounts per asset; the user executes via build_buy_xstock_tx / build_sell_xstock_tx / build_deposit_yield_tx and signs in their own wallet. Allocation base = USDC + held xStocks + held yield tokens (SOL is excluded as gas reserve). Each asset gets current% / target% / d

  • track_tx

    Check a Solana transaction's on-chain status. Returns confirmation, success/fail, Solscan URL.

What the publisher says

From the Agent Wallet repository's README, as published. We do not edit it. Read it on GitHub

agent-wallet-mcp

A non-custodial RWA service for AI agents on Solana — yield comparison, tokenized US-equity quotes, and ready-to-sign transactions. Funds stay in your wallet; we never sign.

Connect this MCP server to Claude, Cursor, Claude Code, or any MCP-compatible client. Your AI can then:

  • Compare USDC lending yields across Solana, Ethereum, Base, Arbitrum (read-only data).
  • Quote and build transactions to buy Backed xStocks (16 tickers — NVDAx, TSLAx, SPYx, QQQx, COINx, …) on Solana.
  • Snapshot any wallet's portfolio (SOL, USDC, held xStocks valued live via Jupiter).
  • Track transaction confirmations.

You sign every transaction in your own Phantom (or other Solana wallet). We do not custody funds, hold keys, or co-sign. Architecturally we are a service — closer to Tradingview than to a wallet.

Signals to act on: pair this with StockWaves — pay-per-call quant signals (equities / crypto / cross-asset macro) over the x402 protocol. StockWaves tells an agent what to trade; this server lets it execute non-custodially.

Why this exists

Tokenized US equities (Backed's xStocks, Ondo Global Markets) and on-chain treasury products are the fastest-growing real-world-asset (RWA) category. As of mid-2026 these have real liquidity on Solana — NVDAx, TSLAx, SPYx all carry $300K-$3M each, with ~$5/share trades incurring zero detectable price impact.

Coinbase, Phantom, and Crossmint all offer "agent wallets," but they are generic. None opinionated about RWA discovery, yield aggregation, or the boring-but-correct execution that makes idle USDC actually earn. This server fills that gap, distributed via the AI tool layer.

Install

Add to ~/Library/Application Support/Claude/claudedesktopconfig.json (Claude Desktop on macOS) or your editor's MCP config:

{
  "mcpServers": {
    "agent-wallet": {
      "command": "npx",
      "args": ["-y", "@kaditang/agent-wallet-mcp"]
    }
  }
}

The npm package is published as @kaditang/agent-wallet-mcp (and listed in the official MCP Registry) — the config above runs it directly via npx, no clone needed. Requires @kaditang/agent-wallet-mcp ≥ 0.2.1 (stdio entry).

To run from source instead (for development), clone this repo and run:

bash

git clone https://github.com/kaditang/agent-wallet-mcp.git

cd agent-wallet-mcp && npm install

cp .env.example .env # then fill in SOL_RPC (api keys are minted via Phantom at /account)

npm run mcp:http # serves on :3030

Then point your MCP client at http://localhost:3030/mcp with an Authorization: Bearer header.

Solana RPC endpoint (recommended)

Public RPCs (api.mainnet-beta.solana.com) rate-limit aggressively and reject getTokenAccountsByOwner in some cases. For any meaningful traffic you want a paid endpoint as primary; public ones are kept as fallback automatically.

Free tier from Helius is enough for V1:

  1. Sign up → New project → copy the RPC URL (looks like https://mainnet.helius-rpc.com/?api-key=...)
  2. Set in .env:
SOL_RPC=https://mainnet.helius-rpc.com/?api-key=YOUR_KEY
  1. (Optional) add a second provider as SOLRPCFALLBACK_1 for redundancy.

The pool tries primary first; on transient failures (429, timeouts, 5xx) it falls through to fallbacks, then to the public mainnet-beta + publicnode endpoints.

Shortened. The full README is on GitHub.

Nothing above is checked by us. What we check is on the safety report.

Install directly

Runs npx -y @kaditang/agent-wallet-mcp on your machine. Read the scan report first; the gateway never runs local packages.
