Agent Ready Cloudflare

Agent Ready — Cloudflare Scanner

Audit any website for AI agent readiness, generate actionable fix prompts, and implement improvements to increase the agent-ready score.

0. Operational Flow

Follow this flow every time this skill is activated:

Step 1 — Get the domain

If the user did not provide a domain, ask:

Which domain do you want to scan on isitagentready.com?

Step 2 — Scan via API

curl -s -X POST 'https://isitagentready.com/api/scan' \
  -H 'Content-Type: application/json' \
  -H 'User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/145.0.0.0 Safari/537.36' \
  -H 'Referer: https://isitagentready.com/' \
  -H 'Origin: https://isitagentready.com' \
  -d '{"url":"https://DOMAIN/","enabledChecks":["robotsTxt","sitemap","linkHeaders","dnsAid","markdownNegotiation","robotsTxtAiRules","contentSignals","webBotAuth","apiCatalog","oauthDiscovery","oauthProtectedResource","authMd","mcpServerCard","a2aAgentCard","agentSkills","webMcp","x402","mpp","ucp","acp","ap2"]}'

Replace DOMAIN with the target domain.

Step 3 — Generate the Markdown report

Use the API response to build a report with this structure:

# Agent Ready Scan — {domain}

> **Score:** Level {level} — {levelName}
> **Scanned:** {scannedAt}
> **Link:** [View online](https://isitagentready.com/{domain})

## Summary

| Category | Score |
|----------|-------|
| Discoverability | {passed}/{total} |
| Content | {passed}/{total} |
| Bot Access Control | {passed}/{total} |
| API, Auth, MCP & Skill Discovery | {passed}/{total} |
| Commerce (Optional) | {passed}/{total} |

## Details

### Discoverability ({passed}/{total})

- ✅ **robots.txt** — {message}
- ❌ **sitemap.xml** — {message}
  (... for each check ...)

### (... repeat for each category ...)

## 🔧 How to Implement — Agent Prompts

(... one block per failing check, see Step 4 ...)

## Next Level

**Level {nextLevel.target} — {nextLevel.name}**

To reach the next level, implement:
- {nextLevel.requirements[].description}

Step 4 — Generate "How to Implement" prompts

For every check with status: "fail" or status: "neutral", generate a prompt block using the Prompt Templates in Section 8 below. The prompt combines:

1. The Goal and Fix from the template (static per check)
2. The Issue from the API response (checks.{category}.{check}.message)
3. The Skill URL pointing to the sub-skill
4. The Docs links to the relevant RFCs/specs

Format each prompt as a fenced code block the user can copy-paste into a coding agent:

#### ❌ {check name}

**Issue:** {message from API}

```
Goal: {goal from template}

Issue: {message from API}

Fix: {fix from template}

Skill: https://isitagentready.com/.well-known/agent-skills/{skill-folder}/SKILL.md

Docs: {docs URLs from template}
```

> 📖 Reference: [{skill-folder}/SKILL.md]({skill-folder}/SKILL.md)

Step 5 — Deliver

Present the full Markdown report to the user. If they want to save it to a file, write it to the requested path.

1. What It Checks

Discoverability (4 checks)

Content (1 check)

Bot Access Control (3 checks)

API, Auth, MCP & Skill Discovery (8 checks)

Commerce — Optional (5 checks, scored only if e-commerce signals detected)

2. Levels

3. API Reference

Endpoint

POST https://isitagentready.com/api/scan
Content-Type: application/json

Required Headers (Cloudflare protection)

User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/145.0.0.0 Safari/537.36
Referer: https://isitagentready.com/
Origin: https://isitagentready.com

Request Body

{
  "url": "https://example.com/",
  "enabledChecks": [
    "robotsTxt", "sitemap", "linkHeaders", "dnsAid",
    "markdownNegotiation",
    "robotsTxtAiRules", "contentSignals", "webBotAuth",
    "apiCatalog", "oauthDiscovery", "oauthProtectedResource", "authMd",
    "mcpServerCard", "a2aAgentCard", "agentSkills", "webMcp",
    "x402", "mpp", "ucp", "acp", "ap2"
  ]
}

All checks are optional — pass only the ones you want to run.

Set "format": "agent" to get a markdown response with fix instructions instead of JSON (useful for piping directly to an LLM).

MCP Server

The scanner is also available as an MCP server:

https://isitagentready.com/mcp

Call the scan_site tool with a url parameter. See scan-site/SKILL.md.

Discovered Endpoints (isitagentready.com itself)

The scanner practices what it preaches. These are its own agent-ready endpoints:

The API Catalog links the scan API to its documentation (/llms-full.txt), its service description (/.well-known/mcp/server-card.json), and its health endpoint (/api/health).

Status Values

4. Web Interface vs API

This is why this skill includes the full prompt templates below — to reconstruct the web-quality prompts from API data.

5. Batch Scanning

For multiple domains, add a 2-second delay between requests. Write results incrementally to avoid data loss:

import json, time, urllib.request

HEADERS = {
    "Content-Type": "application/json",
    "User-Agent": "Mozilla/5.0 ...",
    "Referer": "https://isitagentready.com/",
    "Origin": "https://isitagentready.com"
}
CHECKS = ["robotsTxt","sitemap","linkHeaders","dnsAid","markdownNegotiation",
          "robotsTxtAiRules","contentSignals","webBotAuth","apiCatalog",
          "oauthDiscovery","oauthProtectedResource","authMd","mcpServerCard",
          "a2aAgentCard","agentSkills","webMcp","x402","mpp","ucp","acp","ap2"]

for domain in domains:
    body = json.dumps({"url": f"https://{domain}/", "enabledChecks": CHECKS}).encode()
    req = urllib.request.Request("https://isitagentready.com/api/scan",
                                data=body, headers=HEADERS)
    with urllib.request.urlopen(req, timeout=90) as resp:
        data = json.loads(resp.read())
    # process data...
    time.sleep(2)

Sub-skill: content-signals/SKILL.md

webBotAuth

Goal: Let your site identify itself as a bot with Web Bot Auth

Issue: {issue}

Fix: Publish a JWKS at /.well-known/http-message-signatures-directory so your site can identify itself when it sends bot or agent requests. Receiving sites can use it to verify those signed requests.

Skill: https://isitagentready.com/.well-known/agent-skills/web-bot-auth/SKILL.md

Docs: https://datatracker.ietf.org/wg/webbotauth/about/, https://developers.cloudflare.com/bots/reference/bot-verification/web-bot-auth/

Docs: https://www.rfc-editor.org/rfc/rfc9727, https://www.rfc-editor.org/rfc/rfc9264

Sub-skill: api-catalog/SKILL.md

oauthDiscovery

Goal: Publish OAuth/OIDC discovery metadata so agents can authenticate with your APIs

Issue: {issue}

Fix: If your site has protected APIs, publish /.well-known/openid-configuration (for OpenID Connect) or /.well-known/oauth-authorization-server (for pure OAuth 2.0) with your issuer, authorization_endpoint, token_endpoint, jwks_uri, and grant_types_supported. This allows AI agents to programmatically discover how to authenticate.

Skill: https://isitagentready.com/.well-known/agent-skills/oauth-discovery/SKILL.md
