What is Crawlbase MCP?

Crawlbase MCP is a Model Context Protocol (MCP) server that bridges AI agents and the live web. Instead of relying on outdated training data, your LLMs can now fetch fresh, structured, real-time content — powered by Crawlbase’s proven crawling infrastructure trusted by 70,000+ developers worldwide.

It handles the complexity of scraping for you:

JavaScript rendering for modern web apps
Proxy rotation & anti-bot evasion
Structured outputs (HTML, Markdown, screenshots)
