What is the Crawlbase MCP Server?
Connect your Crawlbase (formerly ProxyCrawl) account to any AI agent and take full control of your web scraping and anonymous crawling workflows through natural conversation.
What you can do
- Standard Scraper — Identify bounded routing spaces inside the headless engine to extract explicitly attached HTML content via datacenter proxies
- JS Rendering — Discover disconnected physical limits tracking exactly what JS-rendered frames expose to extract exact single-page UI bounds
- Structured JSON Extraction — Analyzes specific global bounds driving auto-extraction pipelines to force raw HTTP outputs into structured JSON format strictly
- Screenshot Capture — Dispatch automated validation checks to generate valid proxy endpoints returning configured Crawlbase screenshot URLs
- Specialized Scraping — Leverage dedicated algorithms for Amazon products, LinkedIn profiles, Facebook pages, and Twitter (X) graph profiles natively
- Search Engine Discovery — Explain explicitly mapped proxy lists targeting Google domains to parse SERP limits and bypass CAPTCHAs limitlessly
- Custom Proxy Management — Provision highly-available request payloads generating custom proxies with specific headers and crawling logic
How it works
- Subscribe to this server
- Enter your Crawlbase Normal Token and your optional JavaScript Token (found in your Crawlbase Dashboard)
- Start scraping and crawling from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Data Analysts — extract structured web data and search engine results without writing complex scraping scripts
- Growth Hackers — monitor competitor products on Amazon or social profiles on LinkedIn and Twitter in real-time
- Developers — test and debug web extraction pipelines and JS-rendering logic through natural conversation
- Market Researchers — perform deep web crawls and capture snapshots of target sites for offline analysis

Frequently asked questions
When should I use the JavaScript (JS) Token versus the Normal Token?
Use the Normal Token for fast, static HTML extraction. Switch to the JavaScript Token when the target site uses frameworks like React or Angular, where content is rendered dynamically in the browser. The 'scrape_js_rendered' tool requires the JS Token to function.
Can my agent bypass CAPTCHAs while scraping Google or LinkedIn?
Yes. Crawlbase is built to handle CAPTCHAs and blocks natively. When you use specialized tools like 'scrape_google_serp' or 'scrape_linkedin', the agent routes your requests through Crawlbase's advanced proxy infrastructure to ensure successful data extraction.
How do I get a structured JSON response instead of raw HTML?
Use the 'scrape_json_format' tool or the specialized scraper tools (Amazon, LinkedIn, etc.). These trigger Crawlbase's auto-extraction pipelines, which analyze the page structure and return specific data fields in a clean JSON format.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your Crawlbase MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
