WebMCP

llms.txt and WebMCP: two pieces for an agentic AI-ready website

llms.txt helps guide language models and WebMCP exposes structured actions for agents inside the browser.

· ·

  • llms.txt acts as a curated map for language models.
  • WebMCP turns key actions into structured tools for agents.
  • Both are progressive enhancements that must sit on top of visible quality content.

What llms.txt adds

An llms.txt file summarises what your business is, which pages matter and which resources a model should read if it wants to understand you. It does not replace the sitemap or website content: it organises them for an AI context.

What WebMCP adds

WebMCP lets a page expose JavaScript tools with descriptions and schemas. For example, an agent could open the consultation questionnaire or read a service summary without guessing how the interface works.

How we apply it

At VisibleAI we add these pieces when they make sense: llms.txt for curated content, JSON-LD for entities and progressive WebMCP for important actions. Everything starts with a fast, accessible and clear website for humans.

  • llms.txt map
  • Schema per page
  • Safe WebMCP tools
  • Visible and verifiable content

How this guide was prepared

This guide combines official search and AI-platform documentation with technical criteria that small businesses can apply. We separate what a website controls—clarity, crawlability, performance, structure and conversion—from decisions made by third-party platforms.

Before prioritising a change, measure the baseline in Search Console and record where each enquiry comes from. That makes it possible to distinguish a useful improvement from a short-lived fluctuation without promising rankings or recommendations.

  • Review indexing, queries and pages before publishing more content.
  • Verify every business claim against a reliable source.
  • Measure clicks, calls and messages, not only impressions.
