@metalift/mcp

Metalift MCP server for AI agents. Exposes scrape, crawl, map, and batch tools over stdio for Cursor, Claude Desktop, and other MCP clients.

What is Metalift?

Metalift Cloud is a hosted web context platform — scrape, crawl, and map sites into LLM-ready markdown for AI agents. This MCP server connects your AI client to the Metalift API.

Get an API key

1. Sign up for Metalift Cloud and verify your email.
2. Complete onboarding and copy your API key from Dashboard → API keys.

New accounts receive 1,000 free credits/month. Set METALIFT_API_KEY in your MCP config (see below). Do not commit keys to git.

Install

Published on npm as @metalift/mcp. Default config uses npx:

{
  "mcpServers": {
    "metalift": {
      "command": "npx",
      "args": ["-y", "@metalift/mcp"],
      "env": {
        "METALIFT_API_URL": "https://api.metalift.ai",
        "METALIFT_API_KEY": "YOUR_API_KEY"
      }
    }
  }
}

Claude Desktop: paste the same JSON into claude_desktop_config.json (Settings → Developer → Edit Config). See MCP setup — Claude Desktop and examples/claude-mcp.json.

Corporate Windows / SSL inspection: if npx fails with UNABLE_TO_VERIFY_LEAF_SIGNATURE, install locally and use node — see examples/claude-mcp-local.json / cursor-mcp-local.json and MCP setup troubleshooting.

Web search vs scrape

Search and scrape are separate tools with separate billing:

1. metalift_web_search — returns up to 10 search snippets (2 credits, English by default). Review titles and snippets first.
2. metalift_scrape — fetches page content for URLs you choose (1+ credits per URL). Default response_detail=compact (~16k chars, no link lists). Use standard for full articles or full for raw JSON with all links.

Do not auto-scrape every search result. See Web search for agent workflow examples.
