Install

How do I install the MAD Synapse · Web & Research MCP server?

MAD Synapse · Web & Research is a hosted endpoint at https://agent.maddegen.art/hub/mcp/web, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
arxiv_search ~217

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).

dns_lookup ~164

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).

domain_whois ~176

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).

email_check ~134

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).

robots_check ~169

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.

web_meta ~171

Everything a page says about itself: title, description, OpenGraph/Twitter card, canonical, favicon, language, RSS/Atom feeds, JSON-LD schema types, headings — and link-preview problems. Use to build link previews, check SEO/social cards, find a site's feeds or structured data. Flags missing og:image, missing description and non-absolute image URLs (common reasons a link shows up bare on X/Telegram). When to use: For title/OpenGraph/canonical; for the article text use web_read. Price: $0.001 per call (10 free/day; after that a payment-required result lists x402 options).

web_read ~233

Any public URL → clean readable markdown: the article/main content without nav, ads or boilerplate, plus title, author, date, word count and links. PDFs too. Fetches the page (redirects followed, public internet only), extracts the main content with Mozilla Readability and converts it to markdown. PDFs are converted to text. Use max_chars to bound the output. JavaScript-only pages return whatever the server sends (no headless browser). When to use: For a page's content; for its metadata only use web_meta; for uptime/redirects use http_probe. 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).

wiki ~206

Wikipedia in any language: search a topic and get the best article's summary, description, thumbnail and link — or the full article text. Search + REST summary from Wikipedia. full=true returns the article as plain text (sections kept), capped by max_chars. Disambiguation pages are flagged with alternatives. When to use: For encyclopedic topics; for papers use arxiv_search or doi_lookup. Price: free. Errors: returns isError with a message for invalid input or an upstream failure (not charged).
