JavaScript/TypeScript SDK for CrawlAPI — web scraping API for AI agents
Crawlapi Js MCP server exists for a simple reason — assistants are far more useful when they can act on Crawlapi Js directly instead of describing what you should do. JavaScript/TypeScript SDK for CrawlAPI — web scraping API for AI agents.
Official JavaScript/TypeScript SDK for CrawlAPI — web scraping API built for AI agents.
Once Crawlapi Js is connected, these are the calls the assistant has available:
LangChain — const client = new CrawlAPI({ apiKey: process.env.RAPIDAPI_KEY });Setup — The Setup tool exposed by this serverThe server ships on npm as crawlapi-js, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
You will need 4 environment variables: CRAWLAPI_KEY, YOUR_RAPIDAPI_KEY, RAPIDAPI_KEY, YOUR_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
This sits in the search and retrieval group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Crawlapi Js's toolset — LangChain, Setup — is a fair guide to whether it matches your workflow. It is maintained by jdwolf96; worth a glance at recent repository activity before you build anything load-bearing on it.
