Agent Readiness Check
www.primitive.dev
Checked 2026-09-08 06:04 UTC
This site is agent-ready
An agent can reach, read and operate this site. What is left is depth: tools it can call, protocols other systems can discover.
Three fixes worth doing first
Ordered by the points still on the table. Each one comes from a documented check and, where it exists, with the code that fixes it.
01Honest annotations on tools
+5 ptsTools are registered without annotations, so an agent cannot tell reads from writes.
How to fix it Set readOnlyHint on every tool that only reads. Set untrustedContentHint where a tool returns text written by other users. Put a confirmation step in front of anything that spends money or changes state.
02Declarative tools on forms
+4 pts1 form(s) could be exposed as tools but none is annotated.
How to fix it Annotate the forms you already ship. Because the attribute names are still marked TODO in the explainer, verify them against the current specification before rolling this out widely.
03robots.txt lets AI crawlers in
+2.5 ptsCCBot cannot read this page.
How to fix it Publish a robots.txt that names the AI agents you want and allows the paths you want cited. Blocking is a legitimate choice — but make it a decision, not an accident.

Your first WebMCP tool, matched to this page
The crawl found a a shop on this site, so the example below registers that as a tool an agent can call. Paste it, point it at your own endpoint, and the page stops being guessed at and starts being called.
registerTool
// Register the first tool an agent can call on this page.
// Works today with the polyfill: npm install @mcp-b/global
await document.modelContext.registerTool({
name: "search_products",

inputSchema: {
type: "object",
properties: { query: { type: "string", description: "Free-text search term" } },
required: ["query"],
},
annotations: { readOnlyHint: true },
execute: async ({ query }, { signal }) => {
const res = await fetch(`/api/products?q=${encodeURIComponent(query)}`, { signal });
return { content: [{ type: "text", text: JSON.stringify(await res.json()) }] };

The full report, plus a re-check in 30 days
Every check with the evidence it was judged on and the code that fixes it, sent as a link that always re-scans. In 30 days we scan again and tell you what moved.
- All checks, pass by pass, with the exact header, count or path behind each verdict
- Copy-paste fixes generated from your own markup
- A re-check in 30 days with the difference, confirmed by you with one click
One email with the report, one re-check after you confirm it, and nothing else unless you ask. No account. Five reports per company per day. What we do with the address.
Agent Tracking
You know whether agents can read this site. Want to know what they do with it?
One line of script records which assistants send visitors, which pages they fetch, which WebMCP tools they call and whether they finish. No cookies, no personal data, hosted in Germany. The check score shows up in the dashboard and is re-scanned monthly.
