WebMCP

This site talks to AI agents

The site registers five tools through the W3C WebMCP API, so a browser agent can search and read articles, fetch contact details and open pages instead of scraping the HTML. Below, you can run each tool yourself.

Tools

The five tools

Each card shows what an agent sees: the name, the description and the input schema. The page runs the same definitions that the site registers, so you can try any of them here.

    Chrome 149 runs an origin trial. For local testing, enable chrome://flags/#enable-webmcp-testing and relaunch Chrome.

  2. 02

    Edge 150 has an origin trial.

  3. 03

    ChatGPT Desktop supports WebMCP. Brave has experimental support in Leo.

Under the hood

How it is built

The five tool definitions live in one module. The plugin registers them with the browser, and this page runs the same definitions, so the two cannot drift apart.

await document.modelContext.registerTool({
  name: 'search_articles',
  title: 'Search articles',
  description: 'Finds blog posts and tool reviews by keyword.',
  inputSchema: {
    type: 'object',
    properties: { query: { type: 'string', description: 'Words to search for' } },
  },
  annotations: { readOnlyHint: true },
  async execute({ query }) {
    // Return a string or a plain object. Throw an Error with a clear message to fail.
    return await findArticles(query)
  },
})

Where the tools run

The tools run in your browser. The site's server only sees the normal page and Markdown requests, and the site sends nothing to any AI provider.
