MCP · AI Agents · Model Context Protocol

AI agents are most useful when they can reach real, live data. The Model Context Protocol (MCP) is the standard for connecting agents to external tools, and today we are releasing an official OpenWeb Ninja MCP server.

Add it once with your API key, and any MCP client (Claude Desktop, Claude Code, Cursor, Cline, Windsurf, and others) gets real-time access to OpenWeb Ninja's APIs as tools. Describe what you want in plain language; the agent picks the right API, calls it, and answers. It can also chain several APIs in one task, and subscribe to an API's free tier on demand.

What you can do with it

Lead generation

Find businesses by location or industry, then enrich with emails, phone numbers, and social profiles.

Market research

Search live Google results, news, forums, and reviews to answer open questions with sources.

Price tracking & comparison

Pull product data from Amazon, eBay, Walmart, Costco, and Wayfair, and compare across them.

Jobs & talent research

Search job listings, salary estimates, and company profiles from JSearch and Glassdoor.

Finance & real estate

How it works

The server exposes one tool per API (40+ of them), plus a subscribe tool. Each tool takes an operation (which endpoint to call) and args (the parameters). The schemas are generated directly from our OpenAPI specs, so the tools always match the live APIs.

Arguments are validated and type-coerced before the request is sent, and responses return the OpenWeb Ninja data payload plus a request_id. A single call to the jsearch tool looks like this:

{
  "operation": "search",
  "args": { "query": "site reliability engineer remote", "country": "us" }
}

40+ tools, one per API

Search & discovery: Web Search, News, Forums, Images, Video, Lens, Reverse Image, Autocomplete, AI Overviews, Google AI Mode, Social Links
Local & maps: Local Business, Yelp, Trustpilot, Local Rank Tracker, Driving Directions, Waze, EV Charge Finder
Jobs & companies: JSearch, Job Salary Data, Glassdoor
Commerce & product: Amazon, Product Search, Walmart, eBay, Costco, Wayfair, Books, Play Store Apps
Real estate: Zillow, Redfin
Finance & events: Real-Time Finance Data, Events
Contact & enrichment: Website Contacts, Email Search
AI relays & utility: ChatGPT, Gemini, Copilot, Web Unblocker

Plus a subscribe tool that adds an API's free tier on demand, so the agent can reach a new data source mid-task.

Set it up

You need an OpenWeb Ninja API key. The server runs via npx, so there is nothing to install globally.

Claude Desktop (claude_desktop_config.json)

{
  "mcpServers": {
    "openwebninja": {
      "command": "npx",
      "args": ["-y", "@openwebninja/mcp-server"],
      "env": { "OPENWEBNINJA_API_KEY": "your-api-key" }
    }
  }
}

Claude Code

claude mcp add openwebninja \
  -e OPENWEBNINJA_API_KEY=your-api-key \
  -- npx -y @openwebninja/mcp-server

Cursor, Cline, Continue, Windsurf, and other clients: use the same command / args / env shape in the client's MCP config.

MCP server or agent skill?

Both connect AI agents to our APIs. Use the MCP server inside a chat client; use the OpenWeb Ninja agent skill for CLI scripts and scheduled pipelines.

	MCP server	Agent skill
Best for	Chatting with an agent (Claude Desktop, Cursor, Cline)	Scripted runs and scheduled pipelines
Setup	One config block, no code	Install the skill, add an API key
Where it runs	Any MCP-compatible client	Claude Code and other agent frameworks
Output	Answers in chat; the agent chains tools	JSON or CSV files, plus webhooks, Sheets, S3
Use it when	You want plain-language access in your assistant	You want repeatable scripts and exports

FAQ

Most common questions and answers

What is the OpenWeb Ninja MCP server?

It is the official Model Context Protocol server for OpenWeb Ninja. It connects any MCP-compatible AI agent to 40+ OpenWeb Ninja web data APIs as tools, so the agent can run web search and pull local business, jobs, e-commerce, real estate, and finance data through one connection.

Which AI clients does it work with?

Any MCP-compatible client, including Claude Desktop, Claude Code, Cursor, Cline, Continue, and Windsurf.

Do I need to install anything?

No. The server runs through npx, so nothing is installed globally. You add it to your MCP client config with your API key.

Is the MCP server free?

Yes. The server is free, and every OpenWeb Ninja API includes a free tier, so you can start without a credit card.

How does my agent authenticate?

Set your OpenWeb Ninja API key as the OPENWEBNINJA_API_KEY environment variable in the MCP config. The server sends it as the x-api-key header on every request.
