soldefi-mcp

An MCP (Model Context Protocol) server that gives AI agents paid access to Solana DeFi risk intelligence — rug/honeypot scans, deep liquidity-pool analysis, and a wash-trade-filtered "real best pools" ranking. Each paid call settles an x402 micropayment in USDC (on Solana or Base) automatically, using a wallet you configure. A call is charged only on success — malformed input is rejected for free.

It talks to the hosted Solana DeFi Intelligence API (https://soldefi.thomenz.me by default). This package is a thin payment-client bridge; the intelligence runs server-side.

Tools

| Tool | Price | What it does | |---|---|---| | scan_honeypot | $0.02 | Rug/honeypot scan of an SPL token by mint: mint/freeze authority renounced?, Token-2022 transfer tax, top-holder concentration, and a live Jupiter buy→sell round trip as a strong signal the token is sellable at scan time (catches most honeypots). Returns a 0–100 risk score + AVOID/CAUTION/LOW RISK verdict. | | analyze_pools | $0.04 | Deep liquidity-pool analysis across Raydium/Orca/Meteora/pumpswap: real fee APR, wash-trade risk, age, TVL, a token rug verdict, and a real Jupiter slippage ladder ($100/$1k/$10k). Recommends the best risk-adjusted pool. | | top_pools | $0.05 | The real best Solana DEX pools — wash-traded/fake-volume pools filtered out, the rest ranked by risk-adjusted fee yield, with an excluded list of what was dropped and why. | | check_lp_status | $0.02 | Liquidity durability / rug-pull exposure: pools (TVL, age, DEX), largest-pool depth, burned-supply share, and whether mint/freeze authority is still live. Returns a 0-100 liquidity-risk score + verdict (DURABLE/SHAKY/FRAGILE/RUG-PRONE). | | check_deployer | $0.03 | Deployer reputation: creator wallet address, creator's remaining holding %, wallet age, and token age. Verdict flags fresh wallets, heavy insider holding, and brand-new tokens. | | can_i_sell | $0.01 | Real-time sellability check at YOUR size: simulates exiting a specific USD amount of a Solana token via a live Jupiter buy→sell round trip and reports USDC recovered, real sell price impact, and tax/friction loss. | | check_exit_risk | $0.04 | Can I get out, and at what cost? Crosses Birdeye smart-money flow (whale net buy/sell 24h, bundler/sniper manipulation tags, 1h sell-pressure, holder count) with a live Jupiter exit-slippage ladder ($1k/$10k) → LOW/ELEVATED/HIGH exit-risk. The sellability wedge: are whales dumping into a thin book that traps you? | | full_scan | $0.08 | One-call full workup: bundles honeypot + LP durability + deployer + exit-risk into a single verdict with an aggregated overall {riskScore, riskLevel, verdict, topFlags} — cheaper than buying the four separately (~$0.11). | | scan_wallet_risk | $0.08 | Portfolio rug scan: reads a wallet's SPL holdings and runs the full honeypot/rug scan on each (up to 10 positions), returning per-token risk and which mints to exit. | | scan_honeypot_batch | $0.10 | Batch rug/honeypot scan: submit up to 10 Solana token mints and get the full per-token honeypot verdict for each in one paid call (cheaper than scanning individually). | | validate_mint | free | Local base58 mint-address format check. No payment. |

Install & configure

Add it to your MCP client (Claude Code, Claude Desktop, …). Only a paying wallet is required — everything else defaults to production.

{
  "mcpServers": {
    "soldefi": {
      "command": "npx",
      "args": ["-y", "soldefi-mcp"],
      "env": {
        "SOLANA_PRIVATE_KEY": "<base58-or-JSON-array secret key of a DEDICATED Solana wallet holding USDC>"
      }
    }
  }
}

You can pay on Base instead of (or in addition to) Solana by setting EVM_PRIVATE_KEY (0x…). If both are set, the x402 layer uses whichever rail the server's payment challenge advertises.

Environment

| Var | Default | Notes | |---|---|---| | SOLANA_PRIVATE_KEY | — | base58 or JSON-array secret key (32 or 64 bytes) of the paying Solana wallet. | | EVM_PRIVATE_KEY | — | 0x-prefixed key of the paying Base wallet. | | SOLDEFI_BASE_URL | https://soldefi.thomenz.me | Point at your own Worker if self-hosting. | | X402_NETWORK | base | base (mainnet → Solana mainnet) or base-sepolia (testnet → Solana devnet). | | SOLANA_RPC_URL | — | Optional RPC used to build the Solana payment (e.g. a Helius URL). Public default otherwise. |

🔐 Security: these keys control real funds. Use a dedicated wallet with a small balance, never a personal/treasury key. Anything that can read this process' environment can spend from it.

The wallet needs

• A little USDC on the chosen chain to pay per call.
• On Solana, a tiny bit of SOL is not required for the payment itself (the facilitator sponsors the transaction fee), but the receiving side must have a USDC token account — which it does on the hosted service.
