CaptureKit MCP updated to the 2026-07-28 spec

We updated the CaptureKit MCP server to the MCP 2026-07-28 specification.

This version of the protocol moves to a stateless request/response core, tightens authorization, and introduces a formal extensions framework. Our server is ready for Claude and other MCP clients as they roll out support.

Nothing changes on your side for day-to-day use. You still get screenshots, content extraction, Markdown, and crawling at https://mcp.capturekit.dev/.

Quick setup

Cursor (Settings → MCP):

{
  "mcpServers": {

      "headers": {
        "x-api-key": "YOUR_API_KEY"
      }
    }
  }
}
