What is the Spider MCP Server?
Connect your AI agent to Spider.cloud — the fastest web scraping API in the market, built in Rust for maximum performance.
What you can do
- Scrape Pages — Extract content from any URL as Markdown, HTML, or plain text. Spider handles JavaScript rendering, anti-bot protection, and proxy rotation
- Crawl Sites — Recursively crawl entire websites at speeds exceeding 100K pages/second. Follow internal links and extract structured data at scale
- Search & Scrape — Search the web and scrape results in a single API call. Combines discovery with extraction for maximum efficiency
How it works
- Subscribe to this server
- Enter your Spider API key (500 free credits to start)
- Your agent can now crawl the web at blazing speed
Why Spider over alternatives?
- 10-20x faster than Firecrawl for large crawls (Rust engine vs Node.js)
- Lower cost per page at high volume
- Built-in stealth mode with fingerprint rotation and residential proxies
Built-in capabilities (3)
Spider.cloud Rust engine follows internal links and scrapes each page. Configure depth and page limits to control scope. Crawl an entire website at blazing speed — up to 100K+ pages/second. Returns content from multiple pages following internal links
cloud Rust-powered engine to scrape a single URL. Handles JavaScript rendering, anti-bot protection, and proxy rotation automatically. Supports multiple output formats: markdown (default), html, text. Scrape a single web page at high speed using Spider.cloud. Returns clean content in Markdown, HTML, or plain text format
Combines search + scrape in one API call for maximum efficiency. Search the web and scrape results in a single high-performance request via Spider.cloud

Frequently asked questions
How is Spider different from Firecrawl?
Spider is built in Rust and optimized for raw speed and volume — it can crawl 100K+ pages per second, making it 10-20x faster than Firecrawl for large-scale operations. Spider also offers lower per-page costs at high volume, built-in stealth mode with fingerprint rotation, and multiple request modes (HTTP, Smart, Chrome). Firecrawl excels at simplicity and LLM-specific features like JSON extraction.
What output formats does Spider support?
Spider supports Markdown, HTML, raw HTML, plain text, JSON (structured extraction), screenshots, and PDF output. You can specify the desired format via the return_format parameter in each request.
How does Spider pricing work?
Spider offers 500 free credits to get started (no credit card required). Paid plans are usage-based with credits consumed per page scraped. The Starter plan begins at $15/month with 12,000 credits. Enterprise plans offer custom pricing with dedicated infrastructure and unlimited concurrency.
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 Spider MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
