Available tools 13

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

email_auth

Email deliverability and spoofing-protection audit for a domain: parses SPF (mechanisms, top-level DNS lookup count, +all/~all/-all), DMARC (policy, pct, rua/ruf, alignment), probes common DKIM selectors, and reports MX, BIMI, MTA-STS and TLS-RPT. Returns prioritised findings with fix hints and a 0-100 score. DNS-based; nested SPF includes are not expanded.

email_check

Email address verification for AI agents and lead-qualification pipelines: syntax check, disposable-domain detection, role-account (info@, support@) detection, free-provider flag, domain typo suggestion (gmial.com -> gmail.com) and DNS MX/A validation via DNS-over-HTTPS. Returns verdict valid, risky, invalid or unknown with a 0-100 score. No SMTP probing, so mailbox existence is not confirmed.

site

site_audit

Technical SEO audit of one page: HTTP status, redirect chain, title and meta description length, H1 count, canonical, robots meta, hreflang, Open Graph and Twitter tags, JSON-LD types, images without alt text, link counts, security headers (HSTS, CSP, X-Frame-Options), technology detection (CMS, framework, analytics, CDN) and a prioritised issue list with a 0-100 score. Static HTML only; honours robots.txt.

site_contacts

Public contact details published on a website: emails (including mailto links and [at] obfuscation, classified role or personal), phone numbers normalised to E.164, social profile links, address hints and Swedish organisation numbers for .se sites. Fetches the given page plus up to 3 contact-like pages (/contact, /kontakt, /about, /om-oss, /impressum) on the same host only. Honours robots.txt; returns 403 blocked_by_robots (not charged) if disallowed.

account

se_account_to_iban

Converts a Swedish clearing number and account number to IBAN and BIC, identifies the bank, and validates the account number checksum according to the bank-specific rules. Clearing table dated 2026-10-16; does not check that the account exists.

bank

bank_days

Adds or subtracts Swedish bank days (weekends, public holidays and midsommarafton, julafton, nyarsafton excluded) to a date. Optional mode=work counts only weekends and red days. Returns the result date with weekday, ISO week and holiday names for both dates.

brand

brand_check

Use before naming a product, company or project. For 1-3 names: domain availability via registry RDAP (DNS fallback), handles on GitHub, Bluesky, npm, PyPI, Telegram (others flagged could_not_confirm with links), exact-name Apple App Store apps, and identical/similar USPTO trademarks with serial, registration number and status. Per-check UTC timestamps, optional free variations and Markdown report. Not legal advice; nothing is registered.

demo

demo

Free static sample output. Pass a paid route slug.

domain

domain_dns

DNS lookup for a domain through DNS-over-HTTPS: A, AAAA, NS, MX, TXT, CAA, SOA, CNAME records with TTLs, plus DNSSEC presence (DNSKEY, DS) and the resolver validation flag. Structured JSON for domain research, due diligence and infrastructure agents.

iban

iban_check

IBAN validation: country-specific length (from a bundled table of IBAN countries), mod-97 checksum, normalised and formatted output, BBAN and check digits. Does not check that the account exists.

pricing

pricing

Free price table and x402 payment instructions.

url

url_markdown

Fetches a web page (up to 1.5 MB, 8 s timeout) and returns clean Markdown: title, headings, paragraphs, lists, links, images, code blocks and simple tables, with navigation and footers removed. Ready to feed to LLMs. Static HTML only, no JavaScript rendering. Honours robots.txt.

validate

se_validate

Validates Swedish identifiers with checksum and date logic: personnummer, samordningsnummer, organisationsnummer (including sole-trader and VAT forms), bankgiro, plusgiro and OCR payment references. Returns normalised forms and error codes. No application-level storage.

What is AgentKit x402 MCP server mostly used for?

Its tools cluster around site and email. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

How do I connect AgentKit x402 MCP server?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does AgentKit x402 MCP server need an API key?

No. AgentKit x402 MCP server completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 13 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is AgentKit x402 MCP server?

It answers our handshake in 146 ms on average, which is faster than 90% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
