Documentation Overview

wallettriage-mcp

MCP server for WalletTriage — real-time exploit-exposure check for EVM wallets, built for AI agents. Each query is paid via x402 (USDC on Base) signed locally by a session key: no signup, no API key, no prompts. Stateless — nothing about you or your queries is persisted.

Tools

check_address_risk (paid) — real-time risk for an EVM address: dangerous ERC20 approvals cross-referenced with a live threat feed of contracts under attack. Returns risk_score (0–100), risk_level and actionable findings.
get_pricing (free) — service status and current price per query.

Setup (Claude Desktop, Claude Code, Cursor)

Requires Node 20+. Add to your MCP config (e.g. claude_desktop_config.json):

config.json

{
  "mcpServers": {
    "wallettriage": {
      "command": "npx",
      "args": ["-y", "wallettriage-mcp"],
      "env": {
        "GATEWAY_URL": "https://api.wallettriage.com",
        "EVM_PRIVATE_KEY": "0xREPLACE_WITH_SESSION_WALLET_PRIVATE_KEY",
        "MAX_PAYMENT_ATOMIC": "100000"
      }
    }
  }
}

Fund the session wallet with a few USDC on Base. Use a dedicated, low-balance wallet — never your main key. It only signs gasless EIP-3009 USDC payments; WalletTriage never holds or moves funds.

EVM_PRIVATE_KEY is the wallet's private key (0x + 64 hex), not its address. No ETH needed — payments are gasless (EIP-3009). Test connectivity first with the free get_pricing tool before funding.

Then ask your agent: "Check the risk of 0xd8dA… before I interact with it."

Troubleshooting

unable to verify the first certificate (common on Windows / corporate networks): your antivirus or proxy intercepts TLS and Node doesn't use the system certificate store by default. Add "NODE_OPTIONS": "--use-system-ca" to the env block. Never disable TLS verification — payments travel in headers and must not be tamperable.
EVM_PRIVATE_KEY is malformed: the value must be 0x + 64 hex characters (the private key of the session wallet). Check for placeholder text, missing 0x or stray whitespace.
Gateway unreachable: GATEWAY_URL defaults to https://api.wallettriage.com. If you overrode it (e.g. to a local gateway), make sure that host is reachable and running.

Environment variables

Variable	Required	Default	Purpose
`EVM_PRIVATE_KEY`	yes	—	Session key that signs x402 payments (USDC on Base)
`GATEWAY_URL`	no	`https://api.wallettriage.com`	WalletTriage API base URL. Defaults to production; set `http://localhost:4021` for local dev (https enforced for non-local hosts)
`MAX_PAYMENT_ATOMIC`	no	`100000` (US$0.10)	Refuses any 402 requirement above this cap (atomic USDC units, 6 decimals)
`DEFAULT_SCAN_CHAIN`	no	`eth`	Default chain: eth, base, polygon, arbitrum, optimism, bsc

Local development

Terminal

npm install
cp .env.example .env   # set EVM_PRIVATE_KEY
npm start              # runs src/server.ts via tsx (stdio)

Point at a local gateway with GATEWAY_URL=http://localhost:4021, or test with the MCP Inspector:

Terminal

npx @modelcontextprotocol/inspector npx tsx src/server.ts

npm run build emits dist/server.js (the published bin).
