What is the Crawlapi Js MCP server?

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.

What you get

Official JavaScript/TypeScript SDK for CrawlAPI — web scraping API built for AI agents.

What the assistant can call

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 server

Setting it up

The 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.

Configuration and credentials

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.

Choosing this one

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.

This entry was verified against Crawlapi Js's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Before you rely on it

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the crawlapi js mcp server does with a few real requests.
