The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

dns_lookup unknown never probed

Context lookup: Resolve a single DNS record type (A, AAAA, MX, TXT, NS, CNAME, SOA, CAA, or SRV) and return the raw answers. Use for quick, targeted lookups of one record type; prefer dossier_dns for a full multi-type DNS audit in parallel, or dossier_full for a complete domain health check. Queries Cloudflare DoH (1.1.1.1/dns-query) over HTTPS, follows CNAME chains, 5 s timeout. Returns a JSON array of answer objects with name, type, and data fields. On error, returns a string describing the DNS failure.

dossier_dkim unknown never probed

Core dossier check: Probe a domain's DKIM public keys by querying <selector>._domainkey.<domain> for each selector. Use to verify signing configuration or discover active selectors; supply selectors when you know the ESP's selector, or omit to probe six common selectors (default, google, k1, selector1, selector2, mxvault). Issues parallel Cloudflare DoH (1.1.1.1) TXT queries per selector, 5 s timeout each. Returns a CheckResult: {status:"ok", found:[{selector, publicKey, raw},...], notFound:[...]} or {status:"error", reason}.

arguments 21 lines

dossier_tls unknown never probed
Core dossier check: Fetch and inspect the TLS certificate presented by a domain on port 443, returning chain details and validity period. Use to verify certificate expiry, issuer, Subject Alternative Names, or detect mismatched or self-signed certs; not a full cipher-suite scanner. Performs a TLS handshake from the server edge, 5 s timeout; extracts the leaf certificate. Returns a CheckResult: on success, {status:"ok", subject, issuer, validFrom, validTo, daysRemaining, sans, fingerprint}; on failure, {status:"error", reason}.

dossier_cors unknown never probed

Core dossier check: Send a CORS preflight OPTIONS request to https://<domain>/ and return the access-control-* response headers. Use to verify CORS policy for a specific origin-method pair, or to check whether a domain allows cross-origin requests; provide origin and method to simulate a precise preflight, or omit to use defaults (origin: https://domainposture.com, method: GET). Single OPTIONS request via fetch, 5 s timeout. Returns a CheckResult: on success, {status:"ok", headers:{access-control-allow-origin,...}}; on failure, {status:"error", reason}.

dossier_web_surface unknown never probed
Core dossier check: Snapshot a domain's public web surface: robots.txt, sitemap.xml, and the home-page <head> metadata (title, description, OpenGraph, Twitter cards). Use for SEO audits, content discovery, or verifying metadata before sharing; for HTTP headers use dossier_headers, for redirect behavior use dossier_redirects. Fetches /, /robots.txt, and /sitemap.xml concurrently via HTTPS, 5 s each; parses <head> with a lightweight HTML parser. Returns a composite CheckResult: {status:"ok", meta:{title, description, og, twitter}, robots, sitemapPresent} or {status:"error", reason}.

Must be resolvable on the public internet; IPs, ports, paths, and protocol prefixes are rejected." } }, "additionalProperties": false }
arguments 14 lines
user_agent_parse unknown never probed
Context lookup: Parse a User-Agent header string into structured browser, OS, device type, and rendering-engine components. Use to identify client capabilities from a raw UA string, e.g. when analysing server logs or request headers; does not perform any network lookups — entirely local parsing. Runs synchronously using the ua-parser-js library with no external calls. Returns a JSON object with browser.name, browser.version, os.name, os.version, device.type, device.vendor, and engine.name fields; unknown fields are empty strings.

{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "ua" ], "properties": { "ua": { "type": "string", "description": "Full User-Agent header value as sent by the browser or HTTP client, e.g. \"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36\"." } }, "additionalProperties": false }
arguments 14 lines
dossier_ai_crawlers unknown never probed
Core dossier check: Report a domain's AI-crawler policy — whether robots.txt allows, blocks, or is silent on the six major AI agents (GPTBot, ClaudeBot, Google-Extended, PerplexityBot, CCBot, meta-externalagent). Use to answer "does this site let AI models train on / retrieve its content?" in a posture audit. Fetches https://<domain>/robots.txt, follows redirects (off-site redirect = no policy), 10s timeout; parses robots groups. Returns a CheckResult; on success { hasRobots, agents: { <agent>: 'allowed' | 'blocked' | 'unspecified' } }. A missing robots.txt is data, not an error (every agent unspecified).

arguments 14 lines
dossier_headers unknown never probed
Core dossier check: Fetch https://<domain>/ and return all HTTP response headers, with an audit highlighting missing or misconfigured security headers. Use to review CSP, HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and Permissions-Policy; for redirect tracing use dossier_redirects instead. Single GET via fetch, 5 s timeout, captures raw response headers before any redirect is followed. Returns a CheckResult: on success, {status:"ok", headers:{...}, securityAudit:[{header, present, value},...]}; on failure, {status:"error", reason}.

arguments 14 lines
ip_lookup unknown never probed
Context lookup: Resolve an IPv4 or IPv6 address to its geolocation, ASN, org name, and city/country. Use when you need network or location context for a raw IP address; prefer dns_lookup or dossier_dns for hostname resolution. Queries ipinfo.io with a server-side token — the token is never exposed to callers. Returns a JSON object with fields ip, city, region, country, org, loc, and timezone. On failure, returns an error string describing what went wrong.

arguments 14 lines
dossier_dns unknown never probed
Core dossier check: Fetch a domain's full DNS profile — A, AAAA, NS, SOA, CAA, and TXT records — all in parallel. Use as the first step of a domain audit or when you need a comprehensive DNS snapshot in one call; prefer dns_lookup for a single record type, or dossier_full for all 10 dossier checks at once. Fires six Cloudflare DoH (1.1.1.1) queries concurrently, each with a 5 s timeout. Returns a CheckResult discriminated union: on success, {status:"ok", records:{a, aaaa, ns, soa, caa, txt}}; on failure, {status:"error", reason}.

Must be resolvable on the public internet; IPs, ports, paths, and protocol prefixes are rejected." } }, "additionalProperties": false }
arguments 14 lines
dossier_mx unknown never probed
Core dossier check: Look up a domain's MX (mail exchanger) records and return them sorted ascending by priority. Use when verifying inbound-mail routing or as a precursor to SPF or DMARC checks; prefer dns_lookup with type=MX if you only need the raw DNS answer without the ranked view. Queries Cloudflare DoH (1.1.1.1), follows CNAME aliases, 5 s timeout. Returns a CheckResult discriminated union: on success, {status:"ok", records:[{exchange, priority},...]} sorted by priority; on failure, {status:"error", reason}.

Must be resolvable on the public internet; IPs, ports, paths, and protocol prefixes are rejected." } }, "additionalProperties": false }
arguments 14 lines
dossier_spf unknown never probed
Core dossier check: Retrieve and parse a domain's SPF record, decomposing it into mechanisms and qualifiers. Use to verify email sender policy, debug delivery failures, or check the 10-lookup limit; pair with dossier_dmarc for full email-auth coverage, or use dns_lookup with type=TXT for the raw record only. Fetches TXT records via Cloudflare DoH (1.1.1.1), 5 s timeout, locates the v=spf1 record and parses all mechanisms. Returns a CheckResult: on success, {status:"ok", raw, mechanisms:[{type, value, qualifier},...], lookupCount}; on failure, {status:"error", reason}.

arguments 14 lines
dossier_dmarc unknown never probed
Core dossier check: Retrieve and parse a domain's DMARC policy from its _dmarc.<domain> TXT record, returning all tags. Use to audit email authentication policy, verify the p (policy) and rua (reporting) settings, or confirm alignment mode; pair with dossier_spf and dossier_dkim for complete email-auth coverage. Queries _dmarc.<domain> via Cloudflare DoH (1.1.1.1), 5 s timeout; parses each tag=value pair. Returns a CheckResult: on success, {status:"ok", raw, tags:{p, rua, ruf, adkim, aspf,...}}; on failure, {status:"error", reason}.

arguments 14 lines
dossier_redirects unknown never probed
Core dossier check: Trace the full HTTP redirect chain starting from https://<domain>/, recording each hop's status code and destination URL. Use to debug redirect loops, verify HTTP→HTTPS upgrades, or audit link shorteners; stops at 10 hops to prevent infinite loops. Follows Location headers with fetch (no auto-redirect), 5 s per hop. Returns a CheckResult: on success, {status:"ok", hops:[{url, statusCode, redirectsTo},...], final}; on failure, {status:"error", reason}.

arguments 14 lines
dossier_dnssec unknown never probed
Core dossier check: Verify DNSSEC chain-of-trust for a domain (DS, DNSKEY, AD flag). Use to confirm the zone is signed and resolvers accept the chain; prefer dossier_dns for raw record types or dossier_full for the complete audit. Fires Cloudflare DoH DS and DNSKEY queries with DO=1; 8s timeout. Returns a CheckResult discriminated union with { dnssecEnabled, adFlag, ds[], dnskey[] } on success.

arguments 14 lines
dossier_mta_sts unknown never probed
Core dossier check: Fetch and validate a domain's MTA-STS policy (mode, mx, max_age, policy id). Use to confirm inbound SMTP is locked to TLS for this domain. Resolves the _mta-sts TXT record, then fetches the policy from mta-sts.<domain>/.well-known/mta-sts.txt; 10s timeout. Returns a CheckResult; not_applicable when no MTA-STS TXT is published.

dossier_whois unknown never probed
Core dossier check: Look up the registrar, creation date, expiry date, and registry statuses for a domain. Use for ownership/expiry audit. Queries WHOIS over TCP/43 via the `whoiser` library; 15s timeout. Returns a CheckResult; not_applicable when the registry refuses or redacts the query (common on cloud IPs).

arguments 14 lines
dossier_llms_txt unknown never probed
Core dossier check: Detect whether a domain publishes an llms.txt at its root — the emerging convention that gives AI agents a curated markdown index of a site's content. Use in a content-posture audit to confirm a site guides (rather than ignores) AI agents. Fetches https://<domain>/llms.txt, 10s timeout; requires a non-HTML content type and a leading markdown H1 (a catch-all SPA answering 200 with HTML is NOT an llms.txt). Returns a CheckResult; on success { bytes, firstLine }; not_applicable when absent.

arguments 14 lines
dossier_security_txt unknown never probed
Core dossier check: Verify a domain publishes a security.txt (RFC 9116) at /.well-known/security.txt — the standard machine-readable channel for reporting vulnerabilities. Use in a security audit to confirm researchers have a published disclosure route; its absence is a genuine (minor) audit flag. Fetches https://<domain>/.well-known/security.txt, 10s timeout; requires a non-HTML content type and a Contact: field. Returns a CheckResult; on success { contact[], expires, raw }; not_applicable when absent.

dossier_full unknown never probed
Aggregate dossier check: Run all 10 Domain Dossier checks — dns, mx, spf, dmarc, dkim, tls, redirects, headers, cors, web-surface — in parallel and return all results in a single response. Use when you need a comprehensive domain health snapshot in one call; counts as ONE paywall call regardless of how many checks run. For a single focused check, prefer the individual dossier_* tools to minimise latency. Fires all 10 checks concurrently via Cloudflare DoH or direct HTTPS, 5 s per-check timeout. Returns a JSON object keyed by check id (dns, mx, etc.), each value a CheckResult discriminated union ({status:"ok",...} or {status:"error", reason}).

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/9adb8f94fde242ae/badge.svg)](https://brick.blue/agent/9adb8f94fde242ae)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know

card completeness

100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
