阅读 https://sourceweft.com/mcp/dev.workers.nightshift-labs.nightshift-x402%2Fagent-safety/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。把它添加到你客户端的 mcpServers 配置中。

}Pay-per-call HTTP API and remote MCP server for agents. No account or API key: each call is paid with an x402 micropayment ($0.003–$0.01 in USDC on Base). Run by Nightshift Labs, an autonomous AI-agent-run business (the code and docs were written by an AI agent).
/, /openapi.json, /.well-known/x402, /llms.txt)https://nightshift-x402.nightshift-labs.workers.dev/mcp — tools are paid per call via x402 (@x402/mcp)/samples shows real example responses for every endpointAny x402 client works. TypeScript with the official SDK:
The payer only needs USDC on Base (EIP-3009 authorization; the facilitator pays gas).
MCP clients: add the remote server URL above. It is listed in the official MCP Registry as
dev.workers.nightshift-labs.nightshift-x402/agent-safety (see mcp-registry/server.json).
Optional: CDP_API_KEY_ID / CDP_API_KEY_SECRET (Coinbase CDP facilitator), BASE_RPC_URL (keyed RPC; free public RPCs are used as fallback).
Local testing without payments works only on testnet: NETWORK=eip155:84532 TEST_NO_PAY=1.
Code layout: app.mjs (Hono app + route table + x402 middleware), lib.mjs (chain/DNS/web logic, SSRF guard), mcp.mjs (MCP server),
preflight.mjs, wallet.mjs, brand.mjs, server.mjs (Node), worker.mjs (Workers).
Heuristic checks (token risk, phishing, wallet screen) reduce risk but are not guarantees; responses state what was checked. Licence: MIT.

Base token safety pre-check: name/symbol/decimals/supply, owner and renounce status, proxy implementation, privileged functions found in bytecode (mint, blacklist, pause, fee setters, upgrade) and a heuristic risk level. Call before buying or accepting an unknown token on Base. Price: $0.01 USDC on Base per call (x402).
address必填Live USD price of any ERC-20 token on Base from on-chain DEX quotes (Uniswap v3 0.05/0.3/1% pools and Aerodrome, against USDC and WETH; WETH converted with Chainlink ETH/USD). Returns the best executable route, every route's price, the price impact of selling $1,000, and flags for thin liquidity or disagreeing pools. Price: $0.005 USDC on Base per call (x402).
address必填Base wallet balances: native ETH and USDC for any address, with the block number they were read at. Price: $0.005 USDC on Base per call (x402).
address必填Decode a Base transaction: status, block time, from/to, ETH value, fee, method selector and every ERC-20 transfer with symbol and human amount. Flags fake look-alike tokens (address-poisoning, e.g. a fake USDC with homoglyph characters). Price: $0.005 USDC on Base per call (x402).
hash必填Domain DNS and email-security check: A/AAAA, NS, MX (incl. null MX), SPF, DMARC policy, CAA, plus a list of issues and a 0-100 email security score. Use before sending email to or trusting a domain. Price: $0.005 USDC on Base per call (x402).
domain必填Decode EVM transaction calldata before signing: finds the function signature (signature DB, verified by re-encoding to reject selector collisions), decodes all arguments, expands multicall batches, and warns about unlimited token approvals, approve-all-NFTs, permits, ownership changes and upgrades. Works for any EVM chain. Price: $0.005 USDC on Base per call (x402).
data必填Check an EIP-712 signature request BEFORE signing (the JSON passed to eth_signTypedData_v4): detects ERC-2612 Permit, DAI permit, Uniswap Permit2 (allowance + transfer) and Seaport orders, explains in one line what the signature grants, and flags drainer patterns: unlimited allowances, spender that is a plain wallet (EOA, checked on Base), zero-payment NFT listings, bulk listings, never-expiring grants. Returns risk (low/medium/high), grants, warnings and the EIP-712 digest. Price: $0.01 USDC on Base per call (x402).
types必填domainmessage必填primaryType必填Base gas snapshot: gas price, base fee, priority fee, 10-block base-fee trend, ETH/USD (Chainlink) and estimated USD cost of an ETH transfer, ERC-20 transfer, swap and contract deploy right now. Price: $0.005 USDC on Base per call (x402).
gasLimitResolve ENS and Basenames (name.eth, name.base.eth): name → address, or address → primary name with forward verification, plus text records (avatar, description, url, twitter, github, email). Price: $0.005 USDC on Base per call (x402).
q必填Domain registration lookup (RDAP, the official WHOIS successor): registration date and age in days, expiry, registrar and its abuse email, EPP status, nameservers, DNSSEC, and flags for brand-new (<30 days) or young domains, punycode/IDN names and expiring domains. Use to vet links, senders and counterparties (phishing domains are usually days old). Price: $0.005 USDC on Base per call (x402).
domain必填DNS lookup in one call: A, AAAA, CNAME, MX, TXT, NS and CAA records with TTLs (or just the types you ask for), NXDOMAIN status, DNSSEC validation, plus parsed hints: SPF record, CAA certificate issuers and which services the domain is verified with (TXT verification tokens). Resolved via DNS-over-HTTPS. Price: $0.003 USDC on Base per call (x402).
name必填typesWebsite security-headers audit: follows redirects (SSRF-guarded) and grades the final page A–F on HSTS, Content-Security-Policy (script-src unsafe-inline/eval/wildcards), clickjacking protection, nosniff, Referrer-Policy, Permissions-Policy, COOP, version-leaking Server/X-Powered-By headers and cookie Secure/HttpOnly/SameSite flags. Returns a score, a list of failed checks with severity, and every header value. Price: $0.005 USDC on Base per call (x402).
url必填Base wallet portfolio: ETH plus 12 major Base tokens (USDC, USDbC, DAI, EURC, WETH, cbETH, wstETH, cbBTC, AERO, DEGEN, VIRTUAL, BRETT) with non-zero balances, USD values from Chainlink ETH/USD and BTC/USD feeds, and a total. Price: $0.01 USDC on Base per call (x402).
address必填x402 seller preflight: check a paid endpoint BEFORE paying. Probes it unpaid, parses the 402 (v2 header or v1 body) and checks each option: scheme, network, asset is real USDC on Base, EIP-712 name/version match on-chain, payTo not a burn address, amount, timeout, discovery metadata. Plus on-chain seller reputation: USDC payments to payTo over 1-7 days (distinct payers, total, last payment). Returns verdict ok/caution/fail, issues and the recommended option. Price: $0.005 USDC on Base per call (x402).
url必填daysmethodWallet / counterparty screen before you send funds or accept a payer: OFAC SDN sanctioned-address check (EVM list, refreshed from the 0xB10C OFAC dataset), address type (EOA, EIP-7702 delegated, contract, token contract), Base and Ethereum tx counts, ETH/USDC balances on Base, burn-address detection and an optional address-poisoning look-alike check against the address you expected (same first/last 4 hex). Verdict block/high_risk/caution/no_red_flags. Price: $0.005 USDC on Base per call (x402).
address必填expectedBrand kit from a website: site name, logo candidates (JSON-LD logo, header/home-link image, inline SVG logo, apple-touch-icon/favicons, og:image), theme-color, CSS brand variables (--primary/--brand/--accent), dominant colors ranked by CSS frequency (non-neutral first), fonts (Google Fonts + CSS font families, system fonts removed) and social profile links. No rendering; flags bot-protected pages. Price: $0.01 USDC on Base per call (x402).
url必填Link / URL phishing pre-check before an agent opens, clicks or forwards a link: brand look-alikes (typosquats, homoglyphs, brand in subdomain), punycode and mixed-script hosts, credentials-in-URL tricks, high-abuse TLDs, domain age via RDAP (new domains flagged), DNS resolution and the full redirect chain. Returns a verdict, a 0-100 risk score and the flags. Price: $0.01 USDC on Base per call (x402).
url必填Fetch any public web page and return clean Markdown of the main content plus title, meta description, word count and absolute links. Strips scripts, navigation and boilerplate. Good for feeding pages to an LLM. Price: $0.005 USDC on Base per call (x402).
url必填maxChars已满足适用检查项的 100%
