常见问题

What is the advantage over traditional web scrapers?

Fetcher MCP uses Playwright to execute JavaScript, enabling it to handle dynamic web content and modern web applications that traditional scrapers cannot.

What are the runtime requirements?

Requires Node.js and Playwright's Chromium browser. Can be run via npx or Docker.

How does content extraction work?

The built-in Readability algorithm automatically extracts the main content from web pages, removing ads, navigation, and other non‑essential elements.

Can I fetch multiple URLs at once?

Yes, the `fetch_urls` tool enables concurrent fetching of multiple URLs with parallel processing for improved efficiency.

What transports are supported?

The server supports both Streamable HTTP endpoint (`/mcp`) and SSE endpoint (`/sse`) when started with `--transport=http`.
