Arachne checks machine-readable signals, then tests whether a bounded agent can actually understand your offer, find the right path, and stop before unsafe actions.
Enter a public website URL once. Arachne checks machine-readable signals, then automatically tests a bounded agent task and builds one combined result.
No signup. No card. Just the Agent Readiness Score.
By submitting a URL, you agree that Arachne may scan publicly accessible pages and signals to generate an Agent Readiness result. Arachne does not log in, bypass access controls, or perform write actions without authorization. See our Privacy Policy.
Arachne turns its capability model into an implementation plan for the interfaces your business actually needs. Existing hosted MCP and OpenAPI outputs remain available, while discovery, browser-agent, agent-to-agent, and commerce surfaces are recommended only when evidence supports them.
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.
Agents and scrapers can already read public pages. Arachne turns that invisible traffic into a governed, logged interface.
Publishing a Shadow API does not grant blanket write access. Reads are structured, writes default to draft_only, high-risk actions require approval, and page content is treated as data rather than instructions. Every call lands in a tamper-evident ledger.
The trade is unmanaged scraping versus accountable access.
Arachne combines structural readiness with live agent validation. Structural readiness measures capabilities across discovery, interfaces, governance, machine understanding, and evidence quality. Signals such as ARD, MCP, A2A, OpenAPI, WebMCP, structured data, sitemaps, and other applicable protocols contribute evidence, but no single file or protocol defines readiness.
When live validation is available, the combined score weights structural evidence at 45% and live agent validation at 55%. Grade: A (90+) · B (75+) · C (60+) · D (40+) · F (<40)
The $99 Agent Readiness Implementation Pack breaks down the evidence, applicable interfaces, prioritized remediation, and the projected score after Arachne compiles supported managed surfaces.
Instant redirect to your Implementation Pack — 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, which starts at $750 setup plus $299/mo and is 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.
