WebMCP Protocols & Briefs
Technical compliance briefs, standards documentation, and reference implementations for engineering teams building machine-readable layouts.
1. Declarative WebMCP Attributes
Conventional search crawlers index static textual pages, but autonomous AI agents (like Claude and OpenAI models) need to click buttons, fill forms, and complete actions. Declarative WebMCP attributes enable developers to decorate native HTML <form> inputs with structured descriptions.
<form
toolname="submit_quote_request"
tooldescription="Submit custom development project requirements to WebMCP"
toolaction="/api/leads"
>
<input type="text" name="domain" required placeholder="https://example.com" />
<input type="email" name="contact" required placeholder="email@domain.com" />
</form>2. /.well-known/webmcp Manifests
Placing a schema manifest file at `/.well-known/webmcp` lets search agents discover valid API parameters without scraping the raw HTML body. Think of it as a `robots.txt` specifically for generative AI actions.
{
"webmcp_version": "1.0",
"tools": [
{
"name": "generate_audit_score",
"description": "Calculates the WebMCP readiness score for a domain URL",

},
"required": ["url"]
}
}

}3. llms.txt Context Indices
The `llms.txt` file format is a newly emerging markdown standard designed to serve concise, structured information specifically to LLMs during their lookup phase. We include complete `llms.txt` maps with every professional integration.
