Les 29 outils

• ai_readiness_audit≈ 195 tokens

  Score how ready a website is for AI agents and LLM-driven discovery, 0-100 with a letter grade: robots.txt presence, explicit AI-crawler policy (GPTBot, ClaudeBot, CCBot, PerplexityBot, and 8 more), llms.txt presence and structure, structured data (JSON-LD) and Open Graph basics, agent/payment discovery files (/.well-known/x402, /openapi.json), sitemap presence, and title/meta basics. The bundle to run before/after making a site agent-friendly — for raw robots/sitemap contents only, use check_robots_sitemap; for classic search SEO only, use seo_audit.

  Paramètres, retour & exemple (1)

  Paramètres

  • url · string · requis
    Any URL on the site to audit (origin is derived from it)

  Exemple de retour

  {"content": [{"type": "text", "text": "…"}]}

• broken_link_check≈ 303 tokens

  Find broken links two ways. Default (crawl mode): crawl a site starting from a URL (same-origin pages only, bounded by maxPages) and check every linked URL for broken status codes, returning each broken link with the page(s) it was found on. Sitemap mode (viaSitemap: true): parse the site's sitemap.xml (following one level of sitemap-index nesting) and check the status of every URL listed in it instead. Note: some external sites (e.g. social platforms) block automated HEAD/GET requests and may show up as false positives.

  Paramètres, retour & exemple (4)

  Paramètres

  • url · string · requis
    Starting URL to crawl — or, in sitemap mode, the sitemap.xml URL or any page URL on the site
  • maxPages · number · optionnel
    Max same-origin pages to crawl in crawl mode (default 20, capped at 50)
  • viaSitemap · boolean · optionnel
    Check the URLs listed in the site's sitemap.xml instead of crawling pages (default false)
  • checkExternal · boolean · optionnel
    Crawl mode only: also check links pointing off-site (default true; crawling never follows off-site links)

• check_open_ports≈ 170 tokens

  TCP-connect scan a host for open ports, plus network intel on the host's resolved IPs (ASN, network owner, BGP prefix, country — via Team Cymru). Defaults to a list of ~20 common service ports (SSH, HTTP/S, mail, DBs, etc.) if none are given. For checking your own infrastructure's exposure — capped at 100 ports per call.

  {"content": [{"type": "text", "text": "…"}]}

• check_robots_sitemap≈ 150 tokens

  Check a site's robots.txt and sitemap.xml in one call: raw contents (truncated), sitemap presence, an AI-crawler policy analysis (explicit rules for GPTBot, ClaudeBot, CCBot, PerplexityBot, Google-Extended, Bytespider, Amazonbot and other AI crawlers, vs wildcard/default), and llms.txt presence. For a scored, whole-site AI-readiness report use ai_readiness_audit instead.

• dns_propagation_check≈ 139 tokens

  Query a DNS record for a domain against several major public resolvers (Google, Cloudflare, Quad9, OpenDNS) in parallel and compare the answers. Flags mismatches, which usually mean propagation is still in progress after a DNS change.

  Paramètres, retour & exemple (2)

  Paramètres

  • domain · string · requis
    Bare domain to query, e.g. example.com
  • recordType · string · optionnel

  {"content": [{"type": "text", "text": "…"}]}

• domain_availability_check≈ 160 tokens

  Check whether a domain is registered, plus scan common typo-squat variants (adjacent-key substitution, letter omission/doubling, transposition) across popular TLDs (.com, .net, .org, .io, .co, .ai, .app, .dev) for brand-protection or domain-flipping research. WHOIS-based; capped at 40 variants checked per call for latency.

  Paramètres, retour & exemple (2)

  Paramètres

  • domain · string · requis
    Bare domain to check, e.g. example.com
  • checkSquats · boolean · optionnel

  Exemple de retour

  {"content": [{"type": "text", "text": "…"}]}

• domain_health_check≈ 143 tokens

  Check a domain's registration expiry (via WHOIS) and DNS health: nameservers, A/AAAA, MX, SPF, and DMARC records. Flags common misconfigurations. WHOIS + DNS only — for the WHOIS record alone use whois_lookup; for deliverability detail (DKIM, DNSBL, PTR) use email_deliverability_check; for all of it plus SEO in one report use domain_report.

  Paramètres, retour & exemple (1)

  Paramètres

  • domain · string · requis

• domain_report≈ 144 tokens

  Bundle: runs seo_audit, domain_health_check (WHOIS + DNS: nameservers, A/AAAA, MX, SPF, DMARC), and email_deliverability_check (DKIM, SPF lookup-count, DMARC strength, DNSBL) against a domain in one call, one charge. Cheaper than calling the three tools separately. Each sub-check reports independently, so a failure in one doesn't void the others.

• email_address_validate≈ 130 tokens

  Validate a single email address: RFC syntax check, MX record lookup on the domain, disposable/temporary-email-provider detection, and role-account detection (info@, admin@, etc.). Per-address check — different from email_deliverability_check, which audits a whole domain's sending reputation (SPF/DKIM/DMARC/PTR/DNSBL).

  Paramètres, retour & exemple (1)

  Paramètres

  • email · string · requis
    Email address to validate

  {"name": "email_address_validate", "arguments": {"email": "texte"}}

  Exemple de retour

  {"content": [{"type": "text", "text": "…"}]}

• email_deliverability_check≈ 175 tokens

  Deep-dive email deliverability check for a domain: MX records + reverse-DNS (PTR) on each MX host, common DKIM selector probing, SPF lookup-count (RFC 7208 caps at 10), DMARC policy strength, and DNSBL blacklist lookups (Spamhaus Zen, SpamCop, Barracuda) on MX IPs. Note: public-resolver DNSBL queries are frequently rate-limited or blocked by Spamhaus, so a `listed: null` result means "unknown", not "clean" — treat null results as inconclusive, not as a clean bill of health.

• exposed_files_check≈ 187 tokens

  Probe a site for publicly exposed sensitive files attackers scan for: /.env and variants, /.git/config and /.git/HEAD, /.svn/entries, docker-compose files, /.aws/credentials, /.ssh/id_rsa, database dumps (backup.sql, db.sql, dump.sql), backup archives, phpinfo pages, .DS_Store, and similar. Reports ONLY reachability metadata (path, status, content type, size) — file contents are never returned or stored. A random-nonexistent-path baseline filters out SPA/catch-all false positives. For auditing your own sites' exposure.

  Paramètres, retour & exemple (1)

• mcp_server_probe≈ 159 tokens

  Probe a remote MCP server end-to-end: performs the initialize handshake, captures server info and protocol version, lists its tools, and grades tool-quality the way directories like Glama do — description coverage and depth, input-schema completeness, and naming consistency — with a 0-100 score, letter grade, and per-tool detail. Use it to vet an MCP server before connecting an agent (or paying per call) to it.

  Paramètres, retour & exemple (1)

  Look up a package (optionally pinned to a version) against OSV.dev's aggregated vulnerability database (GitHub Advisories, PyPA, RustSec, Go vuln DB, etc.) for known CVEs/advisories. Supports npm, PyPI, crates.io, RubyGems, Go, Maven, NuGet, and Packagist ecosystems. Useful before adding a dependency.

  Paramètres, retour & exemple (3)

• page_performance_check≈ 126 tokens

  Fetch a URL and measure time-to-first-byte, total fetch time, and response size from this server. Flags missing compression, missing Cache-Control, oversized payloads, and slow TTFB. Lightweight raw-timing check — for Google Lighthouse scores, Core Web Vitals, and real-user field data use pagespeed_insights instead.

  Paramètres, retour & exemple (1)

  Run Google's real PageSpeed Insights (Lighthouse + Chrome UX Report) against a URL: performance score, Core Web Vitals (LCP, CLS, INP/TBT), and real-user field data where available. The authoritative, Google-measured score — for a quick raw TTFB/size timing check from this server use page_performance_check instead. Works without an API key at low volume; set GOOGLE_PAGESPEED_API_KEY server-side for higher throughput.

• security_headers_audit≈ 157 tokens

  Fetch a URL and audit its response headers in one pass: security headers (HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy) with a score, PLUS its CORS policy (the probe sends a foreign Origin header and flags wildcard-origin + credentials combinations and arbitrary-origin reflection). Header-level checks on a single response — for server/TLS-level checks use ssl_cert_check or ssl_labs_grade instead.

• smtp_server_check≈ 203 tokens

  Live-probe a mail server over SMTP: connects to port 25 (or a given port), reads the banner, issues EHLO and lists advertised capabilities (STARTTLS, AUTH mechanisms, SIZE, 8BITMIME, PIPELINING), then upgrades via STARTTLS when offered and reports the TLS protocol and certificate (issuer, expiry). The server-side complement to email_deliverability_check (which reads DNS records only and never connects). No mail is sent and no relay attempt is made.

  Paramètres, retour & exemple (2)

  Paramètres

  • host · string · requis
    Mail server hostname, e.g. mail.example.com — or a bare domain, in which case its lowest-priority-number MX host is probed

• ssl_labs_grade≈ 152 tokens

  Full SSL Labs-style TLS assessment: overall letter grade, protocol support (TLS 1.0-1.3), cipher strength, certificate chain issues, and known vulnerabilities (Heartbleed, POODLE, etc.) for each endpoint. Use this for a deep grade; use ssl_cert_check instead for a fast expiry/issuer check. Slower (can take up to ~90s on a cold cache; SSL Labs caches results for 24h server-side).

• structured_data_extract≈ 302 tokens

  Fetch a URL and extract structured data deterministically: JSON-LD blocks (each one also VALIDATED — @context/@type presence plus required fields for common schema.org types like Article, Product, Organization, FAQPage), OpenGraph/meta tags, and optional caller-supplied CSS-selector fields (e.g. { price: '.product-price', title: 'h1' }). No LLM involved — pure HTML parsing via CSS selectors, so results are exact matches only, not summarized or inferred. For a whole-page SEO audit (headings, links, images, meta lengths) use seo_audit instead.

  {"content": [{"type": "text", "text": "…"}]}

• subdomain_discovery≈ 144 tokens

  Enumerate a domain's subdomains from public Certificate Transparency logs (crt.sh, with a Cert Spotter fallback): every hostname that has ever appeared on a certificate for the domain. Passive reconnaissance - no packets are sent to the target. Useful for attack-surface reviews, migration inventories, and finding forgotten test/staging hosts.
