About Soldefi Mcp

Soldefi Mcp is an MCP server that provides paid Solana DeFi risk checks through a hosted intelligence API. It is for agents assessing tokens, pools, wallets, and exit conditions, with per-call USDC payments via Solana or Base.

Key features

  1. 01Scan tokens for honeypot risk
  2. 02Analyze liquidity pools and yield
  3. 03Check liquidity and deployer risk
  4. 04Assess wallet holdings and exit risk
  5. 05Build guarded Jupiter swap transactions
  6. 06Pay per request with USDC

Use cases

  1. 01Screen a token before trading
  2. 02Compare pools while filtering wash trading
  3. 03Check whether a position can be sold
  4. 04Scan a wallet's token holdings for risk

MCP support

The server exposes paid risk-analysis and swap-building tools to MCP clients. Calls use x402 micropayments in USDC on Solana or Base; the analysis runs through the hosted Solana DeFi Intelligence API.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

Environment variables to set
SOLANA_PRIVATE_KEYSecretbase58 or JSON-array secret key of a DEDICATED Solana wallet holding USDC (pays per call). Configure this and/or EVM_PRIVATE_KEY; the x402 layer settles on whichever rail the 402 advertises. Paid tools return 402 without one; the free validate_mint tool still works.
EVM_PRIVATE_KEYSecret0x private key of a DEDICATED wallet holding USDC on Base (pays per call). Configure this and/or SOLANA_PRIVATE_KEY; the x402 layer settles on whichever rail the 402 advertises. Paid tools return 402 without one; the free validate_mint tool still works.
SOLANA_RPC_URLOptional Solana RPC override used to build the payment (e.g. a Helius URL). Only read when SOLANA_PRIVATE_KEY is set.
SOLDEFI_BASE_URLBase URL of a soldefi Worker. Defaults to the hosted production API (https://soldefi.thomenz.me).
X402_NETWORKSet to 'base-sepolia' to pay on testnet, which switches BOTH rails (Solana devnet + Base Sepolia). Any other value, including unset, pays on mainnet.

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Details

From the project README

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": "<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
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.

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
