# @leadloadz/mcp-server

A [Model Context Protocol (MCP)](https://modelcontextprotocol.io) server that connects AI assistants to the [Leadloadz](https://www.leadloadz.com) B2B lead generation platform.

## Features

- **Search Leads** — Find verified B2B leads using natural language queries
- **Verify Email** — Real-time email verification with deliverability scoring
- **Get Stats** — Check your usage and remaining quotas
- **Interactive Setup** — Built-in wizard to get your API key
- **Anonymous Telemetry** — Helps us improve the product (no PII, opt-out via `LEADLOADZ_DISABLE_TELEMETRY=1`)

## Quick Start

### Don't have an API key yet?

Run the setup wizard:

```bash
npx @leadloadz/mcp-server --setup
```

This will guide you through creating an account and getting your API key.

### Already have an API key?

Add it to your MCP client configuration (see below) and start using Leadloadz directly.

## Installation

### Via npx (recommended)

No installation required. AI clients can run the server directly:

```bash
npx -y @leadloadz/mcp-server
```

### Via npm

```bash
npm install -g @leadloadz/mcp-server
leadloadz-mcp
```

## Configuration

You need a Leadloadz API key to use this server.

1. Sign up at [leadloadz.com](https://www.leadloadz.com)
2. Go to **Dashboard → API Tokens**
3. Generate a new token
4. Copy the token value

      "args": ["-y", "@leadloadz/mcp-server"],
      "env": {

      }
    }
  }
}
```
