MCP Goes Mainstream as Anthropic Ships Registry, Perplexity Tightens Citation Logic
Anthropic's official MCP server registry launched in late June, giving businesses a verified channel to expose tools directly to Claude agents — and Perplexity quietly updated its ranking signals to weight structured business data more heavily in answer cards. Both moves sharpen the cost of being AI-invisible.
This Week's Signals
Anthropic Launches Official MCP Server Registry, Opening Verified Agent Discovery Channel
Why it matters for your score
Businesses that publish a compliant MCP server and submit to Anthropic's registry can now be surfaced directly inside Claude-powered agents and products — no intermediary needed. This is the first vendor-maintained, crawlable index of agent-callable business endpoints, meaning unregistered competitors become invisible by default. If your service has bookable, purchasable, or queryable actions, not having an MCP endpoint is now a structural discoverability gap.
Perplexity Updates Answer Engine to Prioritize JSON-LD Business Schema in Local and Service Queries
Why it matters for your score
Perplexity confirmed that LocalBusiness, Service, and FAQPage JSON-LD schema now feeds directly into its answer card generation, with structured-data-present pages showing measurably higher citation rates in their internal evals. Businesses without valid schema are being passed over in favor of structured competitors even when raw content quality is comparable. This is the clearest signal yet that schema is a ranking input — not just a formatting nicety — for AI answer engines.
llms.txt Adoption Crosses 40,000 Verified Domains as Cloudflare Adds Native llms.txt Serving to Workers
Why it matters for your score
Cloudflare's Workers platform now auto-serves a validated llms.txt route with one configuration toggle, removing the last major deployment friction for non-technical teams. With 40,000+ domains now publishing the file, AI crawlers including ClaudeBot and PerplexityBot are actively indexing it as a primary context source before touching page HTML. Businesses still without an llms.txt are ceding the first-impression slot to competitors who've claimed it.
What to do this week
- 1
Register your MCP endpoint this week: if you have a bookable, purchasable, or queryable service, use Faro's agent-facing API guidance to build a minimal MCP server and submit to Anthropic's registry before your category fills with early movers. Even a read-only endpoint exposing pricing and availability puts you inside Claude agent workflows.

Run Faro's /tools/ai-schema tool against your homepage and top service pages to validate LocalBusiness and Service JSON-LD — specifically check that 'priceRange', 'areaServed', and 'hasOfferCatalog' fields are populated, since those map directly to the fields Perplexity's June update elevated for answer card generation.

If your llms.txt is missing or stale, regenerate it now with Faro's /tools/llms-txt generator and deploy via Cloudflare Workers using the new native toggle — this gets ClaudeBot and PerplexityBot reading your machine-readable summary before they touch your HTML, giving you control over how AI agents describe your business in recommendations.
