Emerging protocols

0 of 3 detected

Well-known endpoints AI agents look for. Detected here means an agent can discover and connect to your service automatically.

  • OAuth Discovery RFC 8414
    /.well-known/oauth-authorization-server
  • MCP Server Card Anthropic
    /.well-known/mcp.json
  • A2A Agent Card Google
    /.well-known/agent.json

Your site doesn't have an llms.txt file. This is the emerging standard for helping AI agents understand your site structure.

How to implement

Create an /llms.txt file following the llmstxt.org specification. Include a site description and links to your key pages.

Your page has a low ratio of actual content to total HTML. Much of the page weight is markup, scripts, or styles rather than content.

How to implement

Move CSS to external stylesheets, remove inline styles, minimize JavaScript, and ensure the HTML focuses on content structure.

Your site doesn't support Markdown for Agents. This Cloudflare standard lets AI agents request content in markdown format, reducing token usage by ~80%.

How to implement

Implement one or more: (1) Respond to Accept: text/markdown with markdown content. (2) Serve .md URLs (e.g., /page.md). (3) Add <link rel="alternate" type="text/markdown"> tags. (4) Add Link HTTP headers for markdown discovery.

{\n res.setHeader('Vary', 'Accept');\n res.setHeader('Link', '; rel=\"alternate\"; type=\"text/markdown\"');\n if ((req.headers.accept || '').includes('text/markdown')) {\n res.type('text/markdown; charset=utf-8');\n return res.send(renderMarkdown('page'));\n }\n res.render('page');\n});"},{"id":"fastify","label":"Fastify","language":"javascript","filename":"server.js","code":"// Mechanisms 1 + 4: content negotiation + Link header\nfastify.get('/page', async (req, reply) => {\n reply.header('Vary', 'Accept');\n reply.header('Link', '; rel=\"alternate\"; type=\"text/markdown\"');\n if ((req.headers.accept || '').includes('text/markdown')) {\n return reply.type('text/markdown; charset=utf-8').send(renderMarkdown('page'));\n }\n return reply.view('/page.ejs');\n});"},{"id":"nextjs","label":"Next.js","language":"typescript","filename":"app/page/route.ts","code":"// Next.js App Router — Route Handler returning Markdown\nimport { NextRequest } from 'next/server';\nimport { renderMarkdown } from '@/lib/md';\nexport async function GET(req: NextRequest) {\n const accept = req.headers.get('accept') || '';\n if (accept.includes('text/markdown')) {\n return new Response(await renderMarkdown('page'), {\n headers: {\n 'Content-Type': 'text/markdown; charset=utf-8',\n 'Vary': 'Accept',\n },\n });\n }\n // Fall through to the page component\n return new Response(null, { status: 404 });\n}"},{"id":"wordpress","label":"WordPress","language":"php","filename":"functions.php","code":"post_content));\n exit;\n});"},{"id":"static","label":"Hugo / Jekyll / Astro","language":"txt","filename":"static/page.md","code":"# Mechanism 2: serve .md alongside .html\n# Hugo: place page.md in /static/ — built unchanged\n# Jekyll: drop page.md in /assets/ — copied as-is\n# Astro: src/pages/page.md.ts that exports a GET returning markdown\n\n# Then advertise with mechanism 3 in :\n# "}] }'>

Your site doesn't have a robots.txt file. This file controls how bots (including AI agents) access your site.

How to implement

Create a /robots.txt file that allows access to your content pages. Include a Sitemap directive pointing to your sitemap.xml.

No sitemap found. A sitemap helps AI agents discover all pages on your site.

How to implement

Create a /sitemap.xml listing all your public pages. Most CMS platforms can generate this automatically.

No Content-Signal directives found. These tell AI agents how they may use your content (search indexing, AI input, training data). The recommended location is robots.txt.

How to implement

Add Content-Signal to your robots.txt: User-agent: *\nContent-Signal: search=yes, ai-input=yes, ai-train=no. You can also add it as an HTTP header on markdown responses.

{\n res.setHeader('Content-Signal', 'search=yes, ai-input=yes, ai-train=no');\n next();\n});\n\n// Fastify\nfastify.addHook('onSend', (request, reply, payload, done) => {\n reply.header('Content-Signal', 'search=yes, ai-input=yes, ai-train=no');\n done();\n});"}] }'>

Many elements have inline style attributes. These add noise for AI agents extracting content.

How to implement

Move all inline styles to CSS classes in your stylesheet. Use utility CSS frameworks like Tailwind if you need many unique styles.

No Schema.org structured data found. JSON-LD helps AI agents extract factual, structured information from your pages.

How to implement

Add a <script type="application/ld+json"> block with Schema.org markup. Use appropriate types: Article for blog posts, Product for products, Organization for your company page.

No canonical URL found. This helps AI agents identify the preferred version of a page and avoid duplicate content.

How to implement

Add a <link rel="canonical" href="..."> tag pointing to the canonical URL of the page.

[Lightpanda](https://lightpanda.io/) is a headless browser engine built from scratch in Zig for machines. It starts instantly, uses 10x less memory than Chrome, and executes 10x faster.

agent-browser manages Lightpanda the same way it manages Chrome -- spawning the process, connecting via CDP, and shutting it down. All downstream commands (snapshot, click, fill, screenshot, etc.) work through the same CDP protocol path.

## Installation[#](https://agent-browser.dev/engines/lightpanda#installation)

Install the Lightpanda binary before using it with agent-browser:

| Platform | Command |
| --- | --- |
| macOS (Apple Silicon) | `curl -L -o lightpanda https://github.com/lightpanda-io/browser/releases/download/nightly/lightpanda-aarch64-macos && chmod a+x ./lightpanda` |
| Linux (x86\_64) | `curl -L -o lightpanda https://github.com/lightpanda-io/browser/releases/download/nightly/lightpanda-x86_64-linux && chmod a+x ./lightpanda` |

Move the binary somewhere in your `PATH` (e.g. `/usr/local/bin/lightpanda` or `~/.local/bin/lightpanda`).

See the [Lightpanda installation docs](https://lightpanda.io/docs/open-source/installation) for more options.

## Usage[#](https://agent-browser.dev/engines/lightpanda#usage)

Use the `--engine` flag to select Lightpanda:

```
agent-browser --engine lightpanda open example.com
agent-browser --engine lightpanda snapshot
agent-browser --engine lightpanda screenshot
```

Or set it as the default via environment variable:

```
export AGENT_BROWSER_ENGINE=lightpanda
agent-browser open example.com
```

Or in your `agent-browser.json` config:

```
{
  "engine": "lightpanda"
}
```

## Custom Binary Path[#](https://agent-browser.dev/engines/lightpanda#custom-binary-path)

If the `lightpanda` binary is not in your `PATH`, use `--executable-path`:

```
agent-browser --engine lightpanda --executable-path /path/to/lightpanda open example.com
```

## Differences from Chrome[#](https://agent-browser.dev/engines/lightpanda#differences-from-chrome)

Lightpanda is a purpose-built headless engine. Some Chrome-specific features are not available:

| Feature | Status |
| --- | --- |
| Extensions (`--extension`) | Not supported |
| Persistent profiles (`--profile`) | Not supported |
| Storage state (`--state`) | Not supported |
| File access (`--allow-file-access`) | Not supported |
| Headed mode (`--headed`) | Not applicable (headless only) |
| Screenshots | Depends on Lightpanda CDP support |

agent-browser returns a clear error if you combine `--engine lightpanda` with unsupported flags.

## When to Use Lightpanda[#](https://agent-browser.dev/engines/lightpanda#when-to-use-lightpanda)

Lightpanda is a good fit for:

-   Fast web scraping and data extraction
-   AI agent workflows where speed and low memory matter
-   CI/CD environments with constrained resources
-   High-volume parallel automation

Use Chrome when you need full browser fidelity, extensions, or persistent profiles.
