String Web Access — Grok Build plugin

Fetch, search and map any website as clean, LLM-ready Markdown, without getting blocked.

String Web Access handles proxy rotation, anti-bot protection, CAPTCHAs and JavaScript rendering, so the agent gets the page instead of a block screen.

Install

grok plugin install string-web-access

Then set your API key:

export STRING_API_KEY=...

Keys come from portal.usestring.ai.

Tools

Tool	What it does
web_access_fetch	Fetch one URL as Markdown
web_access_request	Send a POST, PUT or PATCH with a body to a URL
web_access_search	Web search with structured results
web_access_sitemap	Crawl a site and return its URLs

web_access_fetch and web_access_search are read-only. web_access_request writes, and web_access_sitemap creates billed crawl jobs, so both prompt before they run. Backed by the hosted MCP server at https://mcp.usestring.ai/v1/mcp.
