What it does
A Firecrawl MCP server written with Effect-TS and the Bun toolchain, designed to run as a local dev server or be deployed as a Vercel serverless function that takes MCP JSON-RPC requests over HTTP. It wraps the Firecrawl JavaScript SDK and works with Firecrawl cloud or a self-hosted instance. A cloud service mode reads each caller's Firecrawl key from request headers, and a safe mode strips interactive scrape actions and turns off browser execution and crawl webhooks. It adds request size limits, per-IP rate limiting, an origin allowlist and Prometheus metrics. Setup guides cover Claude Desktop and LM Studio.
Capabilities
- Scrape and crawl pages through Firecrawl
- Deploy as a Vercel function
- Accept per-request Firecrawl keys in cloud mode
- Export Prometheus metrics
