Description as the publisher wrote it.
| Tool | What it does |
|---|---|
build_utm_url | Build a campaign URL with utm parameters, normalised to one tagging convention, and report which GA4 default channel group the link will land in. Warns about the mistakes that silently break reporting: an unrecognised medium that drops traf Inputs: url, source, medium, campaign, id, term |
capture_full_page_screenshot | Capture a full-height PNG of a page in a real headless browser, scrolling first so lazy-loaded content renders. Returns a signed link to the image that expires in about 24 hours; download the bytes if you need to keep them. No watermark and Inputs: url, refresh, runId |
check_ai_visibility | Check whether AI assistants (ChatGPT, Claude, Perplexity, Google AI) can reach, read, and cite a web page. Runs the full suite: robots.txt rules per AI crawler, a live firewall test that requests the page as GPTBot, JavaScript dependency, l Inputs: url, refresh, runId |
check_favicon | Check whether a site's favicon actually works. Reads every icon declaration in the page head, then fetches each one, the web app manifest, and the implicit /favicon.ico, and identifies the real format and pixel dimensions from each file's h Inputs: url, refresh |
check_robots_txt_for_ai | Test a site's robots.txt against every AI crawler that matters (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, CCBot, Googlebot, Bingbot and the rest) and report which are allowed, which are blocked, and which rule decided it. Also runs Inputs: url, refresh, runId |
check_social_preview | Read a page's Open Graph and Twitter card tags and report how the link will render on X, LinkedIn, Facebook, Slack, Discord, and Google. Returns a per-platform preview (title, description, image) plus the findings for tags that are missing, Inputs: url, refresh, runId |
detect_tech_stack | Identify the platform, framework, CMS, ecommerce apps, analytics, CDN, and hosting behind a site by fingerprinting one page's HTML and response headers. One fetch, no rendering and no crawl, so it answers in about a second. A site behind bo Inputs: url, refresh |
generate_alt_text | Find every image on a page and draft alt text for the ones that need it, using a vision model that actually looks at the image. Lists every image with the alt it has today, the suggested alt, whether it looks decorative, and why any image w Inputs: url, refresh, runId |
generate_json_ld | Read a page and write a schema.org JSON-LD block for it, then validate that block against the same checks a validator would run. The markup is model-written from the page's own content and should be reviewed before it is published. Returns Inputs: url, refresh, runId |
generate_llms_txt | Generate llms.txt and llms-full.txt for a site, following the llmstxt.org convention. Inventories the site from its robots.txt, sitemaps, and homepage links, then writes an index file and a full file with page content inlined. Deterministic Inputs: url, refresh, runId |
hash_md5 | Hash text to an MD5 hex digest. Useful for checksums, cache keys, dedupe keys, and Gravatar-style identifiers. MD5 is broken for anything security-related: never use it for passwords or to verify authenticity. Returns { md5, algorithm, byte Inputs: text |
page_to_markdown | Fetch one web page and convert it to clean CommonMark, with the navigation, cookie banners, and boilerplate stripped out. Use this to read a page as text an agent can reason over, or to publish a .md copy of a page alongside the HTML. Retur Inputs: url, refresh, runId |
validate_json_ld | Read the structured data already on a page and check it against Schema.org and what search engines actually accept. Reports every JSON-LD block found, the type of each, and the errors and warnings per block. Returns { ok, report: { blockCou Inputs: url, refresh, runId |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://usesuperflow.ai/api/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 31 August 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
