Pay-per-call DNS, WHOIS, domain age, TLS, email auth, blocklists, IP intel. Free samples.
how.is domain & IP intelligence's hosted MCP server (how.is), published by how.is; optional API key; Streamable HTTP; 16 tools.
No AI overview yet: these facts come from the registry entry and the server itself.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/is.how%2Fdomain-intel/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

Should an agent click, sign in to, or pay this domain? A risk score and verdict (likely_safe / caution / high_risk, or inconclusive when a check could not run) with plain-English reasons, from domain age, spam/abuse blocklists and the HTTPS certificate. Price $0.020 per call. Free sample: {"domain": "example.com"}. Returns: data: verdict, risk_score (0-100), reasons[{risk, why}], age_days, blocklist_listings, blocklists_unanswered[], https_valid, not_checked[].
domainrequiredDNS records
A, AAAA, MX, NS, TXT and other records for a domain, with resolve timing. Price $0.005 per call. Free sample: {"domain": "example.com"}. Returns: data.data.records keyed by record type (A, AAAA, MX, NS, TXT, ...); data.data.responseTime.
domainrequiredWHOIS / RDAP

72% of the applicable checks met
How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
Publish an icon in the registry entry.
Declare a GitHub repository with a README, or serve resource_documentation in the OAuth protected-resource metadata.
A hosted service is used under its provider's terms, so no license is expected here. This check is left out of the percentage.
