Both projects crawl websites and return Markdown, and both can run on your own machines. That is where the overlap ends. Firecrawl MCP is a thin MCP layer over a crawl platform that is usually hosted. Crawl4AI is an open-source crawler whose Docker server also speaks MCP. This post puts their MCP interfaces on the same rubric rows, checked against each project's docs on 2026-10-27.

Transport and tool surface

Firecrawl's MCP server runs over stdio, as a local Streamable HTTP server, or at a hosted URL with an API key. Its README lists a full profile of more than 25 tools: scrape, map, crawl, search, interaction, agents and monitors. In a client that loads every tool definition upfront, all of those descriptions reach the model in each session unless you use a narrower endpoint.

Crawl4AI's Docker server exposes MCP over SSE at /mcp/sse and WebSocket at /mcp/ws. It registers seven tools: md, html, screenshot, pdf, execute_js, crawl and ask. That is a much smaller footprint in context, but clients that only speak stdio or Streamable HTTP need a bridge.

License and hosting

These are two separate questions. Firecrawl's MCP server is MIT, while Firecrawl's core is AGPL-3.0, and the README says the cloud version has features the self-hosted one lacks. Crawl4AI is Apache-2.0, with an attribution request in its README. If you plan to offer a modified crawler over a network, have someone read the AGPL obligations before choosing. This is not legal advice.

What a failed call costs

Firecrawl's pricing page says requests that return no result are not charged, but a page that responds with an error status such as 403 or 404 is returned and costs one credit. Crawl4AI has no bill: every call, failed or not, costs your own compute and the time someone spends keeping the server healthy. The pricing models guide shows how to estimate a month under each shape.

Which one fits

Choose Firecrawl MCP when you want map, crawl and search behind one hosted URL and do not want to run browsers. Choose Crawl4AI when crawling must stay on your infrastructure, when a permissive license matters, or when seven tools suit your context budget better. If neither crawling nor interaction is the job, a single-page reader may be enough; the Firecrawl MCP alternatives guide sorts every option by reason to switch, and the rubric guide has all ten rows for both.

Frequently asked questions

Can Firecrawl MCP run without the Firecrawl cloud?

Yes. The README documents FIRECRAWL_API_URL for pointing the MCP server at a self-hosted Firecrawl. The core is AGPL-3.0, and the main Firecrawl repository's README notes that the cloud version includes additional features.

Does Crawl4AI's MCP server work over stdio?

The self-hosting guide documents MCP over SSE at /mcp/sse and WebSocket at /mcp/ws on the Docker server. A client that only speaks stdio needs a bridge or a different server.
