MCP server

POST /mcp mounts a Streamable HTTP MCP transport (stateless). Reachable through the same three access paths as GET /take (x402 / API key / keyless).

Tools

  • screenshot — capture a URL as an image. Params: url, format (png/jpeg/webp), plus the common render params (viewport, delay, wait_until, block_ads, block_cookie_banners, dark_mode, full_page).
  • pdf — capture a URL as a PDF. Same common render params; format is fixed to pdf.
  • capture_element — capture a URL after waiting for a CSS selector to appear. Same params as screenshot plus a required selector.

All three tools declare ToolAnnotations: { readOnlyHint: true, destructiveHint: false, idempotentHint: true, openWorldHint: true } and return image + extracted text/metadata content blocks in one call.

Tool-level failures (bad params, navigation failure, timeout) come back as MCP isError: true results with a self-correcting message — never as an HTTP error status, per MCP convention.

Every request must send Accept: application/json, text/event-stream — application/json alone is rejected with 406.
