ai-visibility-mcp
The ai-visibility-mcp server audits and fixes how AI systems (ChatGPT, Claude, Perplexity, etc.) see and access a website, closing the full audit-to-fix loop in a single session.
Audit Tools:
check_ai_bot_access(domain): Analyzesrobots.txtand Cloudflare settings to determine allow/disallow status for 22 known AI user-agents (GPTBot, ClaudeBot, PerplexityBot, etc.).audit_ai_visibility(domain): Generates a 0–100 AI visibility score with explainable deductions covering robots.txt rules, meta tags (noai/noimageai), JSON-LD structured data, sitemap.xml, llms.txt, and SPA shell detection.check_llm_mention(brand, query, aliases?, models?): Queries multiple LLMs simultaneously (Perplexity Sonar, GPT-4o-mini, Gemini 2.0 Flash by default) to measure brand/product presence in AI-generated answers, with per-model mention status, citation counts, and share-of-voice.compare_competitors(your_domain, competitor_domains): Runs parallel visibility audits across your domain and up to 10 competitors, returning a ranked side-by-side comparison of scores, blocked bots, JSON-LD presence, llms.txt, sitemap size, and Cloudflare state.
Fix-Generation Tools:
generate_robots_patch(domain, allow_bots?, deny_bots?): Produces a correctedrobots.txtthat unblocks AI bots while preserving existing rules.generate_json_ld(url, page_type?): Generates Schema.org JSON-LD structured data for a page, with auto-detection of page type.generate_llms_txt(domain, crawl_depth?, max_pages?): Crawls the site's homepage and sitemap to produce a spec-compliantllms.txtfile.
Analyzes website visibility by detecting Cloudflare's AI bot blocking defaults and provides recommendations for improving AI crawler access.
Uses Google's Gemini 2.0 Flash model (via OpenRouter) for brand mention checks and evaluates Google-Extended bot access from robots.txt.
Uses OpenAI's GPT-4o-mini model (via OpenRouter) to evaluate brand mentions in AI responses for cross-model comparison.
Queries Perplexity's sonar model to check if a brand or domain appears in LLM-generated answers, supporting brand visibility analysis.
ai-visibility-mcp
MCP server that audits and fixes how AI sees your website. Robots, schema, LLM mentions, Cloudflare AI defaults — audit the problem, generate the fix, re-audit in one loop.
Most websites are accidentally invisible to AI search. Cloudflare's bot-management defaults block GPTBot / ClaudeBot / PerplexityBot. SPAs render an empty <div id="root"> to crawlers that don't run JS. Marketing teams have no idea their brand isn't surfacing in ChatGPT, Claude, or Perplexity answers — until traffic dries up.
ai-visibility-mcp closes the audit-and-fix loop inside a single agent session:
Audit — find what's blocking AI visibility
Fix — generate the artifact that corrects it
Paste — site owner applies the output
Re-audit — verify the fix was picked up
Tools
Audit tools
Tool | Purpose | Needs API keys? |
| Per-bot robots.txt + Cloudflare AI-default flag for 22 AI user-agents | No |
| 0-100 composite score with explainable deductions (robots, meta, JSON-LD, sitemap, llms.txt, SPA shell) | No |
| Cross-model brand surfacing (Perplexity sonar + OpenAI gpt-4o-mini + Gemini 2.0 Flash by default) | Yes |
| Parallel ranked audit, max 10 in flight | No |
Generator tools (v0.3)
Tool | Purpose | LLM call? |
| Corrected robots.txt that opens access to AI bots; preserves existing rules; detects Cloudflare | No |
| Schema.org JSON-LD block for any page; auto-detects type (Product/Article/Organization/FAQPage/SoftwareApplication/WebSite); validates required fields | Yes (gpt-4o-mini) |
| spec-compliant llms.txt; crawls homepage + sitemap; graceful fallback to link extraction | Yes (gpt-4o-mini) |
Why this exists
Cloudflare flipped defaults in 2024-2025 to block AI scrapers. Most site owners never updated their config, so AI bots get challenged and bounce.
MCP marketplaces shipped in 2026 (MCP Hive, Smithery, mcp.so, Glama). Every AI agent needs tools that can audit the real web. This is one.
Brand visibility in LLM answers is the new SEO. Nobody has a clean stack for measuring it from a single MCP call.

This server makes outbound HTTP requests to caller-supplied domains and to LLM providers. v0.2 hardening:
SSRF guard. All outbound HTTP refuses loopback, link-local (AWS / GCP / Azure metadata IPs), RFC1918, CGNAT, and IPv6 ULA addresses. Redirects are re-validated.
Daily spend cap. LLM calls are gated by
MAX_DAILY_USD(default $5.00), persisted to~/.cache/ai-visibility-mcp/spend.json. Loop-amplification can't drain your Perplexity / OpenRouter credits.Per-call cost ceiling.
MAX_COST_PER_CALL(default $0.10) plusLLM_MAX_OUTPUT_TOKENS(default 1024) hard-bounds any single tool invocation.No persistence of user content. Nothing is logged to disk except the daily spend totals.
Configuration
Env var | Default | Purpose |
| — | Required for Perplexity models in |
| — | Required for OpenAI / Gemini / Claude via OpenRouter |
|
| USD ceiling per tool invocation |
|
| USD ceiling per UTC day, persisted |
|
| Hard cap on output tokens per LLM call |
|
| Override spend ledger location |
Development
uv sync --extra dev
uv run pytest # 40 tests
uv run ruff check . # lintStatus
v0.3 — audit + fix loop complete. 7 tools (4 audit + 3 generator), 40/40 tests, SSRF-hardened, spend-capped. Smoke-verified against tealhq.com / bandcamp.com / anthropic.com.
