Security Report

5.7
Moderate5.7Moderate Risk

The Losbeto MCP server is a market intelligence tool with reasonable security posture for its category. Authentication is optional (free tools work unauthenticated, paid tools require an EVM private key in environment variables). The codebase is clean with proper input validation via URL encoding, no hardcoded secrets, and appropriate error handling. Minor concerns include verbose error logging that could expose implementation details and lack of private key format validation before use. Supply chain analysis found 1 known vulnerability in dependencies (0 critical, 1 high severity). Package verification found 1 issue.

losbeto-mcp

Losbeto x402 market intelligence as native tools in Claude Desktop, Claude Code, or Cursor. Base chain reads with ML on top, ERC-8004 agent reputation, Brazil central-bank macro, multi-oracle price consensus, launch risk, forex, commodities and crypto — plus an OpenAI-compatible LLM gateway. No signup. No API key. Paid tools settle automatically in USDC via x402 — on Base, Solana, Algorand or Polygon.

Registered ERC-8004 agent: agentId 87048 on Base.

Recommended: remote server (no install)

{
  "mcpServers": {
    "losbeto": { "url": "https://api.losbeto.xyz/mcp" }
  }
}

The remote server exposes 5 meta-tools that cover the whole 117-endpoint catalog:

  • search_market_data — FREE. Describe what you need in plain language; get matching endpoints with price and parameters
  • get_market_data — fetch any endpoint (delayed sample FREE; live data at the endpoint's x402 price, from $0.001)
  • market_snapshot — one call for a whole area: brazil, global or crypto
  • list_categories — FREE. Every category, endpoint count, cheapest price
  • account_status — FREE. Subscription/credit status for this connection

Without a key, free tools work and every paid tool returns a real but delayed sample at no cost — enough to judge the data before paying. For live data, add a credit key:

{
  "mcpServers": {
    "losbeto": {
      "url": "https://api.losbeto.xyz/mcp",
      "headers": { "Authorization": "Bearer <credit-key>" }
    }
  }
}

Get a credit key with one on-chain payment — Base, Solana, Algorand or Polygon, your choice: POST https://api.losbeto.xyz/buy-credits (plans from $0.99 with bonus balance; machine-readable at GET /plans).

Chain intelligence + agent-native endpoints (all reachable through the meta-tools above):

EndpointPriceWhat you get
/chain-block$0.001Latest Base block: number, age, gas-used %, base fee
/gas-price$0.001Gas now + ML forecast ~10 min ahead (self-fed Holt smoothing) with send/wait recommendation
/chain-balance$0.002ETH + ERC-20 balances, nonce, wallet-class heuristic
/chain-ens$0.002ENS forward and reverse resolution
/chain-tx$0.002Tx status/value/fee/logs, optional LLM explanation (explain=1)
/agent-reputation$0.010On-chain ERC-8004 identity + aggregated reputation for any registered agent
/wallet-verdict$0.020Graded wallet verdict + LLM roast, idempotent, with shareable SVG card
/x402-watch$0.050Watch any third-party x402 endpoint for 30 days — price/availability changes pushed to your webhook

  "mcpServers": {
    "losbeto": {
      "command": "npx",
      "args": ["-y", "losbeto-mcp"],
      "env": { "LOSBETO_PRIVATE_KEY": "0x..." }
    }
  }
}

LOSBETO_PRIVATE_KEY = an EVM private key holding a little USDC on Base (optional — free tools work without it). For Solana, Algorand or Polygon payments, use the remote server with a credit key instead.

The npm package exposes the classic 9-tool set:

FREE: try_samples (6 live samples in 1 call) · welcome_free_call (one real-time call, no wallet) · launch_risk_preview · receipts (audit our on-chain sales, honestly labeled)

PAID via x402: launch_risk_brief · br_macro (BCB data) · oracle_consensus · fear_greed · sol_price — the exact current price always comes in the tool's own 402 challenge before you pay (typically $0.01–0.10).

For the full catalog (including the chain reads, ERC-8004 reputation and /x402-watch), use the remote server — the npm package is the classic fixed tool set.
