# AgentGauge — full reference

> AgentGauge scans any website and grades how ready it is for AI agents — whether an agent can discover, understand, trust, and transact with the site. The scan is free and returns an instant letter grade against the AgentReady standard, cross-referenced with Cloudflare's Agent Readiness and specification.website. It reads a site exactly the way an agent does: raw HTTP, no browser.

## What we check

AgentGauge grades six areas, mapped to the AgentReady standard and the agent buying journey:

- **Discoverability (Find)** — robots.txt AI policy, sitemap.xml, llms.txt, llms-full.txt, HTTP Link headers. If these are missing, agents never see you.
- **Content for agents (Evaluate)** — Schema.org JSON-LD, Markdown content negotiation, an /index.md fallback, and whether your content is readable without JavaScript.
- **AI Visibility (Recommend)** — will AI answer engines (ChatGPT, Perplexity, Google AI Overviews) cite you? Citable content blocks, answer-shaped pages, author/entity signals, freshness.
- **Capabilities (Use tools)** — MCP servers, A2A Agent Cards, OpenAPI specs, and an /agents entry point.
- **Identity & access (Trust)** — no bot wall blocking agents, Web Bot Auth, OAuth discovery, and discoverable policies.
- **Commerce (Transact)** — agent payment protocols, Product/Offer schema, reachable checkout, and machine-readable pricing.

Each check carries a stable AgentReady ID (e.g. AR-DISC-01) and a strength (MUST / SHOULD / MAY). The report leads with a letter grade plus a baseline-conformance badge.

### Watch by AgentGauge — US$99/year
Your agent readiness silently decays as you ship: a deploy removes your llms.txt, a CMS change strips your JSON-LD, or a new standard lands. Watch (https://www.agentgauge.ai/watch) re-runs the full scan every week and emails you the moment your grade changes — with the fix — plus a short monthly all-clear otherwise. Billed annually, auto-renews, cancel anytime.

### MCP server
Agents can run scans directly: AgentGauge exposes a public MCP server (streamable HTTP, no authentication) at https://mcp.agentgauge.ai/mcp with one tool, scan_website. Connect from Claude Code with: claude mcp add --transport http agentgauge https://mcp.agentgauge.ai/mcp. Metadata at /.well-known/mcp.json and /.well-known/mcp/server-card.json.
