Zenrows MCP Server

The Zenrows MCP (Model Context Protocol) server is the standard way AI systems use Zenrows' web data infrastructure. A single connection gives your AI assistant, agent, or application reliable, real-time access to the live web, including the protected web.

Why Zenrows MCP

• Reach sites that normally block bots. Get reliable access to protected sites at scale, without building anti-bot handling yourself.

• Managed web data infrastructure. Proxy rotation, headless browser orchestration, anti-bot handling, and session management run on Zenrows' infrastructure.

• Plug into any AI you already use. Works with any MCP client, including AI assistants, agent frameworks, AI SDKs, IDE plugins, and custom applications.

• Plain English, no scraping code. Describe the task naturally and the AI picks the right tool. No selectors, no proxy management, no anti-bot tuning.

Quick start

Zenrows MCP supports two transport options. Both expose the same set of tools and capabilities. Pick the one that fits your client.

Remote MCP server

Use the hosted Zenrows MCP server when your AI application calls an LLM API directly. The server runs on Zenrows' infrastructure, so there is nothing to install, configure, or update.

Server URL:

https://mcp.zenrows.com/mcp

Transport: Streamable HTTP

Authentication: OAuth or API key as Bearer token. Pass your Zenrows API key in the Authorization header on every request (or complete OAuth in clients that support it).

Authorization: Bearer YOUR_ZENROWS_API_KEY

Most MCP clients accept this through an authorization shorthand field on the tool config and forward it as the Bearer token automatically. Some clients use a free-form headers field instead. Either approach works.

Remote MCP does not auto-create accounts. Use OAuth “Create Free account” in the client, or pass an existing API key.

Example: OpenAI Responses API

import os
from openai import OpenAI

ZENROWS_API_KEY = os.environ["ZENROWS_API_KEY"]
client = OpenAI(api_key=os.environ["OPENAI_API_KEY"])

response = client.responses.create(
    model="gpt-5",
    tools=[
        {
            "type": "mcp",
            "server_label": "zenrows",
            "server_description": "Web scraping MCP server for accessing live web content.",
            "server_url": "https://mcp.zenrows.com/mcp",
            "authorization": ZENROWS_API_KEY,
            "require_approval": "never",
        }
    ],
    input="Visit https://news.ycombinator.com/ and summarize the three most recent posts.",
)

print(response.output_text)

Local MCP server

Use the local stdio configuration when your MCP client runs the server as a local subprocess instead of calling a remote URL. This is the standard setup for desktop AI tools and IDE plugins, including Claude Desktop, Claude Code, Cursor, Windsurf, VS Code, Zed, and JetBrains IDEs.

Package: @zenrows/mcp on npm

Authentication:

1. ZENROWS_API_KEY environment variable, or

2. Key previously stored in ~/.zenrows/secrets.json, or

3. Auto-signup (default): if neither is set, stdio provisions a Free plan account via POST /api/agent/signup, persists the key + claim metadata under ~/.zenrows/ (secrets.json + account.json, mode 0600), and prints a claim URL on stderr. Opt out with ZENROWS_AUTO_SIGNUP=false.

Requirements: Node.js installed (for npx to work).

Configuration (with your own key):

{
  "mcpServers": {
    "zenrows": {
      "command": "npx",
      "args": ["-y", "@zenrows/mcp"],
      "env": {
        "ZENROWS_API_KEY": "YOUR_ZENROWS_API_KEY"
      }
    }
  }
}

Zero-config (auto-signup):

{
  "mcpServers": {
    "zenrows": {
      "command": "npx",
      "args": ["-y", "@zenrows/mcp"]
    }
  }
}

The exact location of this config varies by client. See the per-client setup guides for the file path for your client.

Tools

The Zenrows MCP exposes these tool families:

The AI selects the right tool from your prompt. You don't call tools directly in code.

See the full tool reference for every tool, parameter, and return value.

Development

git clone https://github.com/ZenRows/zenrows-mcp
cd zenrows-mcp
npm install
cp .env.example .env   # Optional: add your API key (stdio can auto-signup)
npm run dev            # Run with .env loaded (requires Node.js 20.6+)
npm run build          # Compile to dist/
npm run inspect        # Open the MCP inspector UI
