    How to connect

    How to connect OrionCMD Checks to Claude

    The server address to paste into Claude settings:

    https://api.orioncmd.com/mcp

    1. Open Claude (claude.ai or the desktop app).
    2. Go to Settings → Connectors.
    3. Click Add custom connector.
    4. Paste the server address copied below into Remote MCP server URL and click Add.
    5. In a chat, click + → Connectors and switch the new connector on.

    Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

    Authorization

    After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

    How to connect OrionCMD Checks to ChatGPT

    The server address to paste into ChatGPT settings:

    https://api.orioncmd.com/mcp

    1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
    2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
    3. Open Settings → Connectors and click Create.
    4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
    5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
    6. In a new chat open + → Apps/Connectors and enable the connector.

    OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

    Authorization

    On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

    Server tool list (10)

    Raw names from tools/list. Only developers need these.

    validate_targetFree. Check that a domain or URL is well-formed and get the normalized hostname, before calling a paid check. Offline: no network request, no payment. Rejects IP addresses, single-label names and URLs with credentials.
    pricingFree. Return the price of every paid tool, the payment network (Base) and the receiving address, so you can budget before calling. No input, no network request, no payment.
    check_certCheck the TLS certificate of one hostname: issuer, validity dates, days left, % of lifetime used, renewal cadence and a renewal-stall flag, plus a live HTTPS pass/fail probe. Use it when you only need certificate health; use site_health for cert + DNS + expiry together, or domain_grade for a scored A-F result. Certificate details come from public Certificate Transparency logs (Cert Spotter, crt.sh fallback), not from the live connection, so a brand-new cert may not show yet. Read-only; makes one HTTPS request to the host and one CT-log query, usually 1-5 s. Costs $0.01 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input or an upstream failure returns an error and is not charged.
    check_dnsLook up the live DNS of a domain: NS, A/AAAA/CNAME, MX, SPF, DMARC, CAA (climbing to the parent zone) and DNSSEC status, with plain-English findings. Use it for a DNS inventory or to debug resolution; use check_email_auth for a deeper SPF/DMARC/DKIM/MTA-STS review. Queries Cloudflare DNS-over-HTTPS (1.1.1.1) at call time; read-only, nothing is stored. Costs $0.01 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input or an upstream failure returns an error and is not charged.
    check_domain_expiryCheck when a domain registration expires: registrar, registered and expiry dates, days left, EPP status codes and nameservers, from the registry's RDAP server. Use it for renewal risk on the registered domain (not the certificate; use check_cert for that). Some TLDs publish no RDAP service, in which case found=false explains why. Read-only. Costs $0.01 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input or an upstream failure returns an error and is not charged.
    site_healthRun check_cert, check_dns and check_domain_expiry together and return their raw results plus a short summary, the renewal-stall flag and the Let's Encrypt 64-day certificate note (from 2027-02-10). Use it for a full data dump in one call; use domain_grade if you want a single scored A-F answer that also covers email auth and HTTP headers. If one or two sources fail you get partial=true with the rest. Read-only. Costs $0.03 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input or an upstream failure returns an error and is not charged.
    check_email_authReview the email authentication setup of a domain: SPF validity and DNS-lookup count (limit 10), DMARC policy, pct and reporting, DKIM on common selector names, MTA-STS mode, TLS-RPT and BIMI, with a rough 0-100 score and plain-English fixes. Use it before sending mail from a domain or when mail lands in spam. DKIM is only checked on common selectors, so "not found" is not proof DKIM is missing. Live DNS via Cloudflare DoH; read-only, no email is sent. Costs $0.01 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input or an upstream failure returns an error and is not charged.
    check_security_headersCheck the HTTP security headers of a website with one live HTTPS GET: redirect chain (up to 5 hops), final status, HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy and COOP, with a simple A-F header grade and findings. Use it for web-hardening checks; it is not a vulnerability scan. The page body is not read or stored. Costs $0.01 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input or an upstream failure returns an error and is not charged.
    domain_gradeGrade a domain's security posture A-F in one call, for vendor-risk or due-diligence checks. Runs the TLS, DNS (DNSSEC, CAA), registration-expiry, email-auth and HTTP-header checks and returns one letter, a 0-100 score, points per category (TLS 25, email 25, headers 20, DNS 15, registration 15) and the top fixes. Use it when you want a verdict; use site_health or the single checks when you need raw data. Unavailable categories are left out of the percentage (partial=true). Read-only; takes about 3-10 s. Costs $0.03 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input or an upstream failure returns an error and is not charged.
    full_site_auditFull site audit report for one domain, for client reports, vendor reviews or a pre-launch check. Runs every check (TLS from CT logs + live probe, DNS/DNSSEC/CAA, registration expiry and transfer lock, SPF/DMARC/DKIM/MTA-STS, security headers) plus HTTP->HTTPS redirect, www/apex consistency, RFC 9116 security.txt, robots.txt and sitemap. Returns the A-F grade and score (same weights as domain_grade), an action plan sorted critical > high > medium > low where each item has the exact fix and effort, and every raw section. Use domain_grade for just the letter. Fails (not charged) if 3+ core checks fail. Read-only; about 5-15 s. Costs $2 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input or an upstream failure returns an error and is not charged.
