Preflight by x402station.io — infrastructure for x402 agentic commerce. Six capability directions (Discover/Evaluate/Pay/Monitor/Recover/Analyze). Agents call it before every PAYMENT-SIGNATURE to detect decoys, zombie endpoints, dead services, and price traps. Tools: preflight ($0.001), forensics ($0.001), catalogdecoys ($0.005), alternatives ($0.005), whatsnew ($0.001), buycredits ($0.50 = 1000 prepaid), watchsubscribe ($0.01) + free creditsstatus/watchstatus/watchunsubscribe. Plus free anonymous preflight-trial for self-test. Probes 50k endpoints on agentic.market every 10 min. Open dataset: huggingface.co/datasets/x402station/preflight-dataset-v01. npx -y x402station-mcp.
Local stdio MCP server for x402-powered paid crypto intelligence: preflight checks, trade decisions with decisionid, later audit against real prices, risk state, signal history, and agent automation search over USDC micropayments on Base.
Tools & Capabilities Breakdown
X402station Tools (10)
preflight
Preflight x402 scam check: endpoint risk before you pay — decoy / zombie / price-trap / never-paid? Trust verdict in ~200ms before PAYMENT-SIGNATURE.
forensics
Forensic x402 scam/risk report for a suspicious endpoint: probe history, signatures, decoy / price-trap patterns.
catalog_decoys
Searchable catalog of x402 endpoint risk signals; scam-like decoys, zombies, and price-traps flagged.
buy_credits
Prepaid credit pack for high-frequency x402 scam checks, preflight, and verified calls. Returns { creditId, balance, expiresAt }; use X-Credit-Id on subsequent preflight calls.
credits_status
Free, no payment required. Returns { creditId, balance, initialBalance, used, paidAmount, createdAt, expiresAt, expired, paymentTx, paymentNetwork }. UUID-only access — anyone holding the creditId can read state, same as decrement. 404 covers both 'malformed UUID' and 'no such credit' (same body so an attacker scraping random UUIDs can't tell them apart).
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
X402station is categorized under Aggregators and uses a local stdio subprocess. In contrast, Coinopai MCP belongs to Aggregators using local stdio subprocess. Select X402station when you need capabilities focused on aggregators and Coinopai MCP when you require tools for aggregators.
Polling-friendly catalog diff. Body { since?, limit? } (default since=now-24h, limit=200, max 500). Returns added_endpoints[] (first_seen_at >= since AND is_active=true), removed_endpoints[] (flipped to is_active=false since), service-level counts, polls_in_window, and current active totals. Cheap ($0.001 USDC) so hourly polling stays under $1/month — perfect for aggregator agents that need a fresh delta without re-pulling the whole catalog. Internal ingest cron runs every 5 min, so polling more often than that returns identical data.
alternatives
Avoid paying unsafe x402 endpoints: ranked safe alternatives for the same capability.
watch_subscribe
Monitor x402 endpoint risk; webhook on scam-like decoy / zombie / price-trap status changes. Returns watchId + secret; x402station.io posts HMAC-SHA256-signed JSON when subscribed signals fire or clear.
watch_status
Returns the current state of a watch: active/expired, alerts remaining (out of 100 prepaid), last 10 alert deliveries with their delivery_status, and the last computed signal snapshot. Free — no payment required, secret-gated. The secret is the one returned by watch_subscribe.
watch_unsubscribe
Deactivates the watch — no further alerts will be queued or delivered. The subscription is set is_active=false but the row + alert history is retained for audit. Free — no payment required, secret-gated. There is no refund for unused prepaid alerts.

get_agent_automation
Get the full agent automation prompt and workflow steps by slug. Costs $0.01 USDC.
list_automation_categories
List all 35 automation categories with counts. Costs $0.005 USDC.
get_crypto_signals
Latest Kronos model context for BTC, ETH, SOL, XRP, ADA. Directional values are supporting context, not standalone trade instructions; use them with the calibrated range, risk state, and audit record. Costs $0.05 USDC.
get_crypto_risk
Current market risk state and cooldown context for Kronos decisions. Useful as supporting context, not a standalone trading command. Costs $0.02 USDC.

Recent Kronos context history for BTC/ETH/SOL/XRP/ADA. Use it to inspect model context and freshness before or after a decision. Costs $0.05 USDC.
get_crypto_decision
Create a market-intelligence journal entry from Kronos context. Returns directional_bias, confidence context, compliance metadata, regime, anomaly/calibration context, and a decision_id. Call audit_trade_decision with that ID after the evaluation window to see what happened. Costs $0.15 USDC.
check_trade_preflight
Step 1 of the auditable decision loop. Checks market state, cooldown, data freshness, and model context before calling get_crypto_decision. Costs $0.05 USDC.
audit_trade_decision
The accountability step. Verify a Kronos decision_id against later market prices. Returns whether direction held, PnL%, and a verdict: GOOD_DECISION, BAD_DIRECTION, NOISE, or NO_ACTION_TAKEN. Costs $0.07 USDC.
get_crypto_forecast
Conformally-calibrated price forecast: an honest 80% prediction interval (range_80, ~0.80 empirical coverage) plus point return and upside probability for BTC/ETH/SOL/XRP/ADA. Directional bias is supporting context; the calibrated range is the validated product. Costs $0.05 USDC.
