Web Scrapper Stdio MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. Or with Docker Compose: sh docker compose --profile service up -d .
Once Web Scrapper Stdio is connected, these are the calls the assistant has available:
Transport — The Transport tool exposed by this serverYou will need 3 environment variables: MCP_HTTP_HOST, CAPTCHA_API_KEY, CAPTCHA_BASE_URL. 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.
Installation goes through your MCP client rather than a global install: point it at ghcr.io/justazul/web-scrapper-stdio on a container image and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
This sits in the browser automation group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Web Scrapper Stdio's toolset — Transport — is a fair guide to whether it matches your workflow. It is maintained by JustAzul; worth a glance at recent repository activity before you build anything load-bearing on it.
