Spider Cloud plugin for Grok Build

The fastest web crawling, scraping, search, and browser automation for AI agents — delivered through the hosted Spider Cloud MCP server, with built-in anti-bot bypass, proxy rotation, and AI-driven extraction.

What this plugin ships

• 1 MCP server — the hosted Spider endpoint at https://mcp.spider.cloud/mcp, exposing crawl, scrape, search, links, screenshot, unblocker, transform, credits, AI extraction, and remote browser-automation tools.
• 3 skills — spider (overview + tool-selection guide), spider-crawl-scrape (crawling, scraping, search, bot bypass), and spider-browser (interactive browser sessions).

Authentication

The Spider MCP server uses OAuth — on first connection the agent prompts you to authorize in the browser, with no API key to paste. The bundled .mcp.json just points at the hosted endpoint:

{
  "mcpServers": {
    "spider": {
      "type": "http",
      "url": "https://mcp.spider.cloud/mcp"
    }
  }
}

The endpoint advertises OAuth via protected-resource metadata with dynamic client registration and PKCE, so MCP clients authorize automatically.

API-key alternative. The server also accepts a Bearer API key if you prefer not to use OAuth — add an Authorization header to the config:

"headers": { "Authorization": "Bearer ${SPIDER_API_KEY}" }

with SPIDER_API_KEY from https://spider.cloud/api-keys.

Core tools run on pay-per-use credits (no subscription required). The AI tools require an AI subscription.

Network & credentials (for review)

• Endpoint called: https://mcp.spider.cloud/mcp (the official Spider Cloud hosted MCP server) and its OAuth discovery/authorization endpoints under the same host. No other network endpoints.
• Credential: none stored by the plugin. Auth is OAuth (browser authorization, tokens managed by the MCP client) or, optionally, a user-supplied SPIDER_API_KEY sent only as the Authorization: Bearer header to the endpoint above. Nothing is read from the filesystem and no telemetry is collected by this plugin.
