ChainProbe — deep address intelligence
chainprobe auto-detects whether an address is a token or wallet:
Token input → safety score 0–100 covering: contract verification, token age, holder count, CoinGecko listing, Blockscout scam flag.
Wallet input → wealth tier (RETAIL / HOLDER / WHALE / MEGA_WHALE), activity type (HUMAN / BOT / INACTIVE), full token portfolio with USD values, total net worth estimate, and risk flags.
{ "address": "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913" }
→ { "type": "token", "score": 95, "risk_level": "LOW", "verdict": "Token passes all major safety checks." }
{ "address": "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045" }

Setup
1. Get USDC on Base
You need a small amount of USDC on the Base network to pay for tool calls. ~$5 covers hundreds of calls.
- Buy USDC on Coinbase
- Send to your wallet on Base network
- Export your wallet's private key (Coinbase Wallet → Settings → Manage wallets → Export private key)
2. Install
git clone https://github.com/clearcheck-uk/voltix-mcp
cd voltix-mcp
npm install
3. Add to Claude Code
claude mcp add voltix-tools --scope user \
-e PRIVATE_KEY=0xYOUR_PRIVATE_KEY \
-- node /path/to/voltix-mcp/server.mjs
4. Add to Claude Desktop
Add to your claude_desktop_config.json:
{
"mcpServers": {
"voltix-tools": {
"command": "node",
"args": ["/path/to/voltix-mcp/server.mjs"],
"env": {
"PRIVATE_KEY": "0xYOUR_PRIVATE_KEY"
}
}
}
}
Usage in Claude
Once connected, just ask Claude naturally:
- "Use chainprobe to check if 0x1234... is safe to buy"
- "Search the web for latest Base chain news"
- "What's the current gas price on Ethereum?"
- "Look up what ENS name vitalik's address resolves to"
- "Remember this in agent_memory under namespace my-project: key='goal', value='build DeFi bot'"
Security
- Your private key never leaves your machine — it's only used locally to sign payment authorizations
- Each payment is a signed EIP-3009
TransferWithAuthorization — the signature authorizes a specific amount to a specific recipient at a specific time
- Payments are structural micropayments, not on-chain transactions — there is no gas cost
