What the AI Agent Readiness Checker checks

Check whether AI agents and browsers can read and use a site: llms.txt syntax and links, Lighthouse’s Agentic Browsing checks, WebMCP form coverage, Markdown responses for Accept: text/markdown, and MCP or A2A agent cards. Paste an llms.txt draft to validate it before it ships.

  • llms.txt syntax and whether its links load
  • Lighthouse's Agentic Browsing checks
  • WebMCP coverage of the site's forms
  • Markdown responses for Accept: text/markdown
  • MCP and A2A agent cards

What it does not do

  • Layout shift (use the Core Web Vitals Snapshot)
  • A full accessibility audit
  • Testing JavaScript-registered tools end to end

Questions about the AI Agent Readiness Checker

What is llms.txt?
llms.txt is a proposed Markdown file at the root of a site that gives language models a short summary and links to the pages worth reading. It is optional. Paste a draft here to validate it, or draft one with the llms.txt Generator.
Why serve Markdown to AI agents?
Some agents request pages with an Accept: text/markdown header because Markdown is shorter and cleaner to read than HTML. The checker tests whether your site answers those requests with Markdown.
What are agent cards?
Discovery files that describe what an AI agent can do on a site, published for the Model Context Protocol (MCP) or the Agent2Agent (A2A) protocol. The checker looks for them and reports what it finds.
How much does the AI Agent Readiness Checker cost?
10 credits per run, shown before the run starts. An AI agent can run the same tool over the REST API or MCP with a workspace API key.
