Superflow Free Tools MCP¶

Website QA and AI-visibility tooling as one keyless remote MCP server. Superflow Free Tools exposes 13 QA tools over Streamable HTTP with no account and no API key: AI visibility checks across ChatGPT, Claude, Perplexity and Google AI, robots.txt testing against every major AI crawler, llms.txt generation following the llmstxt.org convention, JSON-LD validation and generation, social preview checks, tech stack detection, full-page screenshots, alt text drafts, a UTM builder, page-to-Markdown conversion, favicon checks and MD5 hashing.

Server type: Hosted remote (Streamable HTTP)
Endpoint: https://usesuperflow.ai/api/mcp
Auth: None (no account, no API key)
Tools: 13 (verified live Aug 21, 2026)
Server: superflow-free-tools v1.0.0
Registry: ai.usesuperflow/tools
Built by: Superflow (usesuperflow.ai)

Why This Matters for Operators¶

AI-driven search is now a real acquisition channel, and almost nobody measures whether their site is reachable to the AI crawlers that matter. The individual checks here exist as scattered one-off tools; Superflow packs the whole pre-publish and post-publish QA loop into a single endpoint an agent can call mid-workflow. An agent drafting a landing page can generate the llms.txt, validate the JSON-LD, confirm the social preview renders on LinkedIn, and verify GPTBot can still crawl the robots.txt - all in the same conversation, with no setup beyond pointing the client at the URL.

The keyless design is the adoption hook: zero signup friction, tools are stateless and read-only (plus a UTM builder and MD5 hash), and the server runs on the vendor's infra.

Tools & Capabilities¶

Tool	What it does
`check_ai_visibility`	Checks whether ChatGPT, Claude, Perplexity and Google AI can reach, read, and cite a page
`check_robots_txt_for_ai`	Tests a site's robots.txt against GPTBot, ClaudeBot, PerplexityBot, Google-Extended, CCBot and other AI crawlers
`generate_llms_txt`	Generates llms.txt and llms-full.txt for a site per the llmstxt.org convention, inventorying the site from robots.txt
`page_to_markdown`	Converts a page to clean CommonMark with navigation, cookie banners and boilerplate stripped
`generate_json_ld`	Writes a schema.org JSON-LD block for a page and validates it against the same checks a validator runs
`validate_json_ld`	Checks the structured data already on a page against Schema.org and what search engines accept
`check_social_preview`	Reads Open Graph and Twitter card tags and reports how the link renders on X, LinkedIn, Facebook, Slack, Discord
`detect_tech_stack`	Fingerprints a page to identify platform, framework, CMS, ecommerce apps, analytics, CDN and hosting
`check_favicon`	Verifies a site's favicon works, reading every icon declaration and fetching each one
`capture_full_page_screenshot`	Captures a full-height PNG in a real headless browser, scrolling so lazy content renders
`generate_alt_text`	Finds images on a page and drafts alt text using a vision model that actually looks at them
`build_utm_url`	Builds a campaign URL with UTM parameters normalized to one tagging convention and reports the GA4 default channel group
`hash_md5`	Hashes text to MD5 for checksums, cache keys and dedupe keys

Live probe Aug 21, 2026: server superflow-free-tools v1.0.0, all 13 tools above confirmed on the endpoint.

Installation¶

claude mcp add --transport http superflow https://usesuperflow.ai/api/mcp

{
  "mcpServers": {
    "superflow": {
      "type": "http",
      "url": "https://usesuperflow.ai/api/mcp"
    }
  }
}

No API key, no account, no self-hosting. Any MCP client that supports Streamable HTTP can connect directly. Documentation lives at usesuperflow.ai/tools/mcp.

Configuration¶

Nothing to configure. Tools are stateless: each call takes the URL or text it operates on as a parameter. Rate limits are not published; treat the free endpoint as best-effort and batch heavy crawls accordingly.

Business Relevance¶

Marketing teams validate every landing page's AI visibility, JSON-LD and social previews before launch
SEO operators audit llms.txt and robots.txt coverage as AI search becomes a measurable channel
Content teams produce clean Markdown, alt text and UTM-tagged campaign URLs from one toolset
Agencies run competitor tech stack detection on prospects without a separate vendor tool

Integration with CorpusIQ¶

The AI-visibility checks pair naturally with CorpusIQ's search console and analytics surfaces: check_ai_visibility and check_robots_txt_for_ai identify gaps in AI-crawler reach, CorpusIQ's Search Console connector tracks conventional Google performance on the same pages, and GA4 confirms whether traffic actually follows. For link campaigns, build_utm_url output can be fed straight into CorpusIQ's campaign tracking rather than hand-built tagging.

Limitations¶

13 tools live (the directory submission lists 19; the endpoint exposes 13 as of Aug 21, 2026)
Read-only QA tooling plus a UTM builder and MD5 hash - no crawl infrastructure, no indexing writes
No published rate limits on the free keyless endpoint
Tools operate on one URL per call; bulk site audits require the agent to loop
