Solana DeFi risk intel over x402: rug/honeypot scans, pool analysis, wash-filtered pools.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Crypto & blockchain
  • You need to fill in: SOLANA_PRIVATE_KEY, EVM_PRIVATE_KEY

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: SOLANA_PRIVATE_KEY, EVM_PRIVATE_KEY, SOLANA_RPC_URL, SOLDEFI_BASE_URL, X402_NETWORK

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

    Optional Solana RPC override used to build the payment (e.g. a Helius URL). Only read when SOLANA_PRIVATE_KEY is set.

    Set to 'base-sepolia' to pay on testnet, which switches BOTH rails (Solana devnet + Base Sepolia). Any other value, including unset, pays on mainnet.

Common questions

Is Soldefi 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: SOLANA_PRIVATE_KEY, EVM_PRIVATE_KEY

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 (0.5.2) reached the registry 3 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?

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

ToolPriceWhat it does
scan_honeypot$0.005Rug/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$0.015Deep 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$0.02The 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$0.005Liquidity 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$0.01Deployer 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$0.003Real-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$0.015Can 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$0.03One-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 (~$0.035).
scan_wallet_risk$0.03Portfolio 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$0.02Batch 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).
build_guarded_swap$0.001 + 0.5%Build a ready-to-sign Jupiter swap with the rug check in front: a critical verdict on the token you are BUYING returns the verdict and no transaction. Returns an UNSIGNED versioned transaction — your wallet signs, this service never custodies funds. The 0.5% platform fee applies only when SELLING into USDC/SOL (buying is fee-free) and rides inside the transaction you sign.
validate_mintfreeLocal 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": " " } } } }

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
VarDefaultNotes
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_URLhttps://soldefi.thomenz.mePoint at your own Worker if self-hosting.
X402_NETWORKbasebase (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.
