Read the web (page text, DNS, WHOIS, TLS, uptime) + research (Wikipedia, arXiv, GitHub, packages).
Scored across 15 tools
Each tool targets a distinct source/action and the descriptions explicitly cross-reference neighbors ('for DNS use domain_whois', 'for content use web_read, for metadata use web_meta'). The cluster around web_read/web_meta/http_probe and dns_lookup/domain_whois/tls_check is cleanly separated by intent. No plausible misselection remains.
Strong, uniform snake_case with a consistent resource-prefix pattern (arxiv_search, dns_lookup, web_read, tls_check, package_info). Minor deviations: 'wiki' is a bare noun and a couple use resource+noun rather than resource+verb, but the pattern stays predictable throughout.
15 tools is squarely in the well-scoped range for a web-and-research server, and each tool maps to a distinct source or check (four content sources, three domain/infra checks, page/tls/http probes, package and repo vetting). Nothing appears redundant or filler.
Coverage is broad: scholarly search, citations, books, HN, Wikipedia, page reading/metadata, and a solid infra-vetting suite (DNS, WHOIS, TLS, HTTP, robots, email). The main gap is a general web search engine tool, which is a notable omission for a 'Web & Research' server but one agents can partially work around via wiki/HN/web_read.
Search arXiv research papers by keywords, author or category — newest or most relevant — with abstracts, authors, dates and PDF links. arXiv's official API. query supports arXiv syntax (ti:, au:, abs:, cat:cs.AI, AND/OR). Paced to arXiv's one-request-per-3-seconds policy and cached, so repeated queries are instant. Price: $0.001 per call (10 free/day; after that a payment-required result lists x402 options). Errors: returns isError with a message for invalid input or an upstream failure (not charged).
Inputs: query (required), sort, limit. Returns: query, papers, total_results
Find books by title, author, subject or ISBN: first published year, editions, ISBNs, page count, ratings, subjects and cover image. Open Library (Internet Archive) catalogue of 30M+ titles. Price: $0.001 per call (10 free/day; after that a payment-required result lists x402 options). Errors: returns isError with a message for invalid input or an upstream failure (not charged).
Inputs: query (required), limit. Returns: books, total
All DNS for a domain — A, AAAA, CNAME, MX, NS, TXT, CAA, SOA — plus SPF and DMARC parsed and graded, so an agent knows where a domain points and whether its email can be spoofed. Queried live against public resolvers (Cloudflare, Google, Quad9). Email grade: SPF present and ending in -all/~all, DMARC present with p=quarantine/reject. When to use: For DNS records; for ownership dates use domain_whois; for certificates use tls_check. Price: free. Errors: returns isError with a message for invalid input or an upstream failure (not charged).
Inputs: domain (required). Returns: a, mx, ns, caa, +7 more
Resolve a DOI — or search a paper title — to full citation metadata: title, authors, journal, year, citations count, publisher, license, and a ready-made APA/BibTeX citation. Crossref's open metadata (150M+ works). Search mode returns the top matches for a title/author query. When to use: For citation metadata of a known paper; to search preprints by topic use arxiv_search. Price: $0.001 per call (10 free/day; after that a payment-required result lists x402 options). Errors: returns isError with a message for invalid input or an upstream failure (not charged).
Inputs: doi, limit, query. Returns: apa, doi, url, type, +13 more
Who registered a domain and when: registrar, creation/expiry dates, age, days to expiry, status locks, nameservers — or that it looks available to register. Uses RDAP, the registries' official successor to WHOIS (rdap.org bootstrap). A domain with no RDAP record and no DNS is reported as likely available. Young domains (< 30 days) are flagged: most phishing/scam sites are days old. When to use: For registration and expiry; for DNS records use dns_lookup. Price: $0.002 per call (10 free/day; after that a payment-required result lists x402 options). Errors: returns isError with a message for invalid input or an upstream failure (not charged).
Inputs: domain (required). Returns: dnssec, domain, source, status, +10 more
Will this email address work? Syntax, domain MX records, disposable/throwaway provider detection, role address (info@, admin@) and free-mail provider — without sending anything. No SMTP probing (that gets servers blacklisted); the verdict is from syntax, live MX lookup and a maintained list of ~100k disposable domains. Price: $0.001 per call (10 free/day; after that a payment-required result lists x402 options). Errors: returns isError with a message for invalid input or an upstream failure (not charged).
Inputs: email (required). Returns: mx, email, domain, verdict, +5 more
A GitHub repository at a glance: stars, forks, open issues, last commit, latest release, license, languages, contributors, archived — is it alive and trustworthy? From the GitHub REST API. "activity" summarizes days since last push and last release so an agent can judge whether a project is maintained. Price: $0.002 per call (10 free/day; after that a payment-required result lists x402 options). Errors: returns isError with a message for invalid input or an upstream failure (not charged).
Inputs: repo (required). Returns: url, repo, forks, stars, +16 more
Search Hacker News stories and comments by keyword, sorted by relevance or date, filtered by time window and minimum points — what developers are saying about anything. Algolia's official HN search.

Errors: returns isError with a message for invalid input or an upstream failure (not charged).
Inputs: query (required), days, sort, type, +2 more. Returns: query, total, results
Is a site up and how is it served: status, full redirect chain, timings (DNS/TLS/first byte/total), server, CDN, caching, compression, and a graded security-header check (HSTS, CSP, frame, sniffing…). One real GET from our server. The security grade counts HSTS, Content-Security-Policy, X-Frame-Options/frame-ancestors, X-Content-Type-Options, Referrer-Policy and Permissions-Policy. When to use: For availability, status and timings; for page content use web_read. Price: $0.001 per call (10 free/day; after that a payment-required result lists x402 options). Errors: returns isError with a message for invalid input or an upstream failure (not charged).
Inputs: url (required). Returns: up, cdn, url, bytes, +12 more

May I crawl this? Checks a URL against the site's robots.txt for any user-agent, lists sitemaps and crawl-delay, and reports which AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended…) the site blocks. Standard robots.txt matching (longest match wins, Allow beats Disallow on ties, * and $ wildcards). Missing robots.txt = everything allowed.
