AI agents are coming to your site whether you're ready or not. Get a free readiness score in seconds — then unlock the full report with the exact fixes that make your site safe and legible for autonomous agents.
No signup. No card. Just the score.
After unlocking, you'll also see a live preview of the Shadow API Arachne would compile for your domain — with the option to commission a hosted build if you want us to make it real.
Arachne compiles your site into a Shadow API — a native MCP server, an OpenAPI surface, and an agent policy — without you touching your codebase. Preview the exact Shadow API we'd build for you, right now.
We'll verify your domain and get your Shadow API live. No charge until your build is scheduled.
The questions buyers ask most often before clicking unlock.
Your front door is already open. Arachne replaces it with a glass door and a guest log.
Agents are scraping your site right now, anonymously and unauditably. Arachne doesn't make them possible — it makes them visible and accountable. Writes default to draft_only and require explicit approval. Page content is flagged as data, not instructions (the canonical defense against prompt injection). Every call lands in a hash-chained audit ledger you can re-walk. You're trading invisibility for accountability.
Deterministic, 7 weighted signals, max 100. Each is binary — full weight or zero. The weights sum to 100.

| MCP server endpoint | 35 |
| OpenAPI spec at root | 25 |
| llms.txt | 15 |
| sitemap.xml | 10 |
| robots.txt | 5 |
| JSON-LD on homepage | 5 |
| Semantic forms | 5 |

The full $49 report breaks down exactly which signal you missed, why it matters, and your projected score after Arachne compiles a Shadow API.
Instant redirect to your full report — every readiness signal scored with the specific detail, a prioritized fix list, and your projected score after Arachne. Plus a live preview of the Shadow API we'd compile for your domain (real manifest, real tools), and the option to commission a hosted build.
No. One-time, per domain. You only enter subscription territory if you commission a hosted Shadow API ($500 setup + $99/mo), and that's an explicit separate decision on the next page.
The Shadow API works with any MCP-capable agent. Most common: Claude Desktop, plus Claude Code, Cursor, Continue, and custom agents built with LangChain MCP adapters or the OpenAI Agents SDK. One URL, every client.
No. Arachne is fully egress-side — we only see what a normal browser sees on your public site. Domain ownership is proven via a single DNS TXT record. We never touch your code, your database, or your auth system.
