Can't be undone 1Claude Code: ask
  • lion_payment_attempt_readiness_auditPre-spend payment-term trust check for x402 endpoints.No findings

    Why it is in this group

    • The name "lion_payment_attempt_readiness_audit" says "payment": a word that usually means money moves, which cannot be taken back.
    Description, as the server wrote it
    Pre-spend payment-term trust check for x402 endpoints. Before your agent signs a Payment-Signature, call this with a target x402/MCP service URL: LION extracts the target live 402 payment terms (payTo, amount, asset, network, scheme), cross-checks them for drift across public discovery surfaces, and returns payment_attempt_blockers, buyer_policy_fit, canonical_purchase_recipe, funnel_stage, a transparent readiness score, and risk_flags so the agent can decide whether to sign. 0.05 USDC on Base eip155:8453. Unpaid tools/call returns JSON-RPC error -32402 with the x402 paymentRequirement; wallet-capable MCP clients (e.g. Coinbase Payments MCP, AWS AgentCore Payments) auto-construct the EIP-3009 signature. LION does NOT perform payment inside MCP. Checks payment-term consistency only - not a smart-contract security audit, no settlement guarantee, no fund movement.
Changes things 3Claude Code: ask
  • lion_base_dex_signals_jsonLive Base (eip155:8453) DEX market-data feed for trading and research agents.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Live Base (eip155:8453) DEX market-data feed for trading and research agents. Returns a fresh ranked snapshot of active Base tokens with raw on-chain metrics: price_usd, liquidity_usd, volume_h24, volume_m5, price_change_h1/h24, pair_age_hours, dex, and a transparent mechanical activity_score (volume + liquidity + recency). Source: public DexScreener data, no API key. Raw public market data only - not financial or investment advice, no buy/sell recommendation. Pay 0.005 USDC on Base via x402 at the paid route. tools/call returns payment-required metadata only; settle the x402 invoice at the paid route to fetch the live JSON.
  • lion_trend_intent_signal_csvHardware-wallet buyer-intent + self-custody onboarding-friction intelligence as flat CSV.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Hardware-wallet buyer-intent + self-custody onboarding-friction intelligence as flat CSV. Same column set as the JSON variant: Ledger vs Trezor comparison demand, Bitcoin-only wallet research, under-$100 wallet shopper queries, DeFi hardware-wallet intent, decision-stage crypto purchase research. Optimised for spreadsheet / pipeline ingestion and affiliate-routing or comparison-research workflows. Pay $0.01 USDC on Base mainnet via x402 at the paid route. tools/call returns payment-required metadata only; settle the invoice at the paid route to fetch the CSV.
  • lion_trend_intent_signal_jsonHardware-wallet buyer-intent + self-custody onboarding-friction intelligence as JSON.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Hardware-wallet buyer-intent + self-custody onboarding-friction intelligence as JSON. Non-PII public-signal feed covering: Ledger vs Trezor comparison demand, Bitcoin-only wallet research, under-$100 wallet shopper queries, DeFi hardware-wallet intent, and adjacent decision-stage crypto purchase research. Designed for agent routing, affiliate / comparison-content workflows, and research context. Pay $0.01 USDC on Base mainnet via x402 (HTTP 402 + EIP-3009 transferWithAuthorization) at the paid route. This MCP tool does NOT return the dataset; tools/call returns payment-required metadata so an x402-capable client can settle and fetch the JSON directly.
Only reads 1Claude Code: allow
  • lion_adaptive_data_queryLION Adaptive Data Fabric: ONE typed x402 query endpoint that adapts to any agent request over live Base on-chain data, covering multiple verticals from one call.No findings

    Why it is in this group

    • The name "lion_adaptive_data_query" says "query": a word for reading.
    Description, as the server wrote it
    LION Adaptive Data Fabric: ONE typed x402 query endpoint that adapts to any agent request over live Base on-chain data, covering multiple verticals from one call. Query params: source (base_dex | token_risk | defi_yields), token (0x address; for token_risk / single-token base_dex), sort (activity|volume|liquidity|age), limit, min_liquidity, max_age_hours, fields (output projection), q (free-text intent). base_dex = ranked active Base tokens (liquidity, volume, price-change, pair-age, activity_score) via DexScreener; token_risk = token security card (honeypot, buy/sell tax, mintable, owner, holders + mechanical risk_flags) via GoPlus; defi_yields = Base DeFi pools ranked by TVL with APY via DefiLlama. Free self-describing capability manifest at the same URL with ?describe=1 (no payment). Returns typed JSON rows + freshness fields (as_of, data_age_seconds, confidence, source_provider). Public keyless data, no API key. Raw public market data only - not financial or investment advice. Pay 0.005 USDC on Base via x402; tools/call returns payment-required metadata only, settle at the paid route to fetch the live JSON.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
