boo-crypto-mcp

Free MCP server giving AI agents crypto/web3 ground-truth tools. No API key, no signup, no wallet. Calls public data sources (GoPlus, DexScreener, DefiLlama, alternative.me, OFAC list) directly.

Built by Boo. Companion to the paid x402 services:

• base-rugcheck.vercel.app (deeper EVM rug check)
• base-sol-rugcheck.vercel.app (Solana token intelligence)
• booaip.vercel.app (crypto data API)

Tools

• evm_token_rugcheck (token, chain: eth|bnb|base) - GO/CAUTION/DANGER safety verdict
• solana_token_rugcheck (token) - Solana SPL safety verdict
• token_price (token, chain?) - price, liquidity, volume, FDV, age
• defi_protocol_tvl (protocol) - TVL with 1d/7d change
• defi_yields (symbol?, chain?, limit?, safeOnly?) - top APY pools with risk flags
• stablecoin_info (symbol?) - supply, price, peg deviation
• chain_tvl (chain?) - chain TVL, rank, dominance
• fear_greed_index () - market sentiment 0-100
• wallet_sanctions_check (address) - OFAC PASS/BLOCK

Install & build

npm install
npm run build

Test locally (MCP Inspector)

npm run inspector

Use in Claude Desktop

Edit the MCP config (Settings > Developer > Edit Config), add:

{
  "mcpServers": {
    "boo-crypto": {
      "command": "node",
      "args": ["ABSOLUTE/PATH/TO/boo-crypto-mcp/build/index.js"]
    }
  }
}

Restart Claude Desktop. The tools appear under the connectors/tools menu.

Use in Cursor / Cline

Same shape in their MCP settings: command node, args the absolute path to build/index.js.

(Optional) Publish to npm

After npm publish, agents can run it with no local clone:

{ "mcpServers": { "boo-crypto": { "command": "npx", "args": ["-y", "boo-crypto-mcp"] } } }

Notes

• All data is from public sources and is a signal, not financial or legal advice.
• Rug checks are heuristic; a GO is not a guarantee of safety.
