Responded
The server completed its last measured handshake. This is an observation, not a guarantee.

Unmeasured means there is not enough evidence to decide. How these checks work
Start using Penniless Data Utilities
Choose your client, copy the configuration, then enable the server in your client’s MCP settings.
Run this command in your terminal, then restart Claude Code.

Computes the next UTC fire time for a 5-field cron expression (supports steps, ranges, lists, and month/weekday names). Body {expr, after?} -> {ok, next, epochMs}. Costs $0.001 USDC on Base per call.
DiscoveredJSON DNS-over-HTTPS lookup for A, AAAA, CNAME, MX, TXT, NS, SOA, PTR, SRV, CAA. Body {domain, type?} -> {ok, domain, type, status, answers[]}. Costs $0.001 USDC on Base per call.
DiscoveredStructured WHOIS via RDAP for any domain: registrar, IANA id, statuses, expiry/registration dates, nameservers, DNSSEC. Body {domain} -> {ok, found, domain, registrar, status[], events{}, nameservers[], dnssec}. Costs $0.001 USDC on Base per call.
DiscoveredEmail deliverability check: RFC-style syntax plus live MX probe of the domain. Body {email} -> {ok, valid, formatValid, domainHasMx, mx[]}. Costs $0.001 USDC on Base per call.
DiscoveredPopularity and metadata for any public GitHub repo: stars, forks, open issues, watchers, language, license, topics, last push. Body {repo} -> {ok, found, stars, forks, openIssues, language, license, pushedAt}. Costs $0.001 USDC on Base per call.
DiscoveredRepairs malformed LLM JSON: strips Markdown fences and prose wrappers, fixes trailing commas, converts Python literals (True/False/None) and single/unquoted keys, removes comments, recovers balanced JSON from truncated output. Body {input} -> {ok, repaired, applied}. Costs $0.001 USDC on Base per call.
DiscoveredProduces a unified diff plus added/removed counts between two texts (LCS line diff, configurable context lines). Body {old, new, context?} -> {ok, identical, added, removed, hunks, unified}. Costs $0.001 USDC on Base per call.
DiscoveredExtracts clean text, title, headings, links, URLs, and emails from HTML or plain text. Body {input, numbers?, codeBlocks?} -> {ok, source, title, headings, links, urls, emails, text}. Costs $0.001 USDC on Base per call.
DiscoveredConverts a YAML subset (block maps, sequences, nested indentation, scalars, comments) into JSON with no runtime dependency. Body {input} -> {ok, value, warnings}. Costs $0.001 USDC on Base per call.
