A remote MCP server offering read-only trend-intent and Base DEX market signals as JSON or CSV, with x402-paid queries and a pre-spend payment audit.
What you can do
Retrieve hardware-wallet buyer-intent and self-custody onboarding-friction signals as JSON or CSV, covering comparison demand, Bitcoin-only research, budget shopper queries and DeFi intent. Fetch a ranked snapshot of active Base DEX tokens with price, liquidity, volume, price change, pair age and a mechanical activity score. Run one typed adaptive query over live Base on-chain data across base_dex, token_risk and defi_yields sources with sorting and token filters. Audit a target x402 endpoint's live payment terms for drift before signing a payment.
When to use it
Useful for trading or research agents that want crypto market and buyer-intent signals from a hosted feed, or that need to check x402 payment terms before spending. Not needed if you only want free, unauthenticated data sources.
Requirements
A remote streamable HTTP endpoint; no local runtime, packages, environment variables or headers are declared. Queries are described as x402-paid, so a wallet capable of signing x402 payments is implied for paid calls. Network access to the hosted endpoint is required.
Before you install
The tools are described as x402-paid, so calls may cost money and require signing a Payment-Signature with a crypto wallet. The payment audit tool reads a target service's live 402 terms but does not itself guarantee safety. Signals are market and intent data, not financial advice; verify figures before acting.
Enable the server for the chats that should use its tools.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Use with an agent
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.github.LIONMASTER20%2Flion-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.
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.
Takes no parameters.
lion_trend_intent_signal_csv
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.
Takes no parameters.
lion_base_dex_signals_json
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.
Takes no parameters.
lion_adaptive_data_query
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.
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.
