🚀 LeadMagic MCP Server

> [!IMPORTANT]

> This local MCP server is deprecated. LeadMagic now ships a hosted MCP server with OAuth sign-in (no API keys in your client) and the full current tool surface — people/company/jobs search, enrichment, ads research, and bulk:

>

> `https://mcp.leadmagic.io/mcp`

>

> - Setup for every client (Claude, Claude Code, ChatGPT, Codex, Cursor, and more): leadmagic.io/docs/mcp/setup

> - Agent skills: `npx skills add LeadMagic/leadmagic-skills`

> - Claude Code plugin: LeadMagic/leadmagic-claude-plugin · Cursor plugin: LeadMagic/leadmagic-cursor-plugin

>

> The npm package below still works against the REST API with an `X-API-Key`, but it is no longer maintained and misses newer tools. Please migrate to the hosted server.

🚀 Super Easy Installation

⚡ Option 1: Interactive Installer (Recommended)

The easiest way to get started - works on macOS, Windows, and Linux. Our new interactive installer, built with React and Ink, makes setup a breeze.

# 🔥 Using npx (no installation required)
npx leadmagic-mcp-server install

✨ The installer will:

• ✅ Validate your API key in real-time and show your remaining credits.
• ✅ Automatically detect and configure your preferred AI tool (Claude, Cursor, VS Code, etc.).
• ✅ Create all necessary config files and a local `.env` for development.
• ✅ Provide usage examples and helpful links.

📱 Option 2: Quick Manual Setup

If you prefer manual setup or are using a client like Aider, you can add the server configuration directly to your client's settings file. The interactive installer provides copy-pasteable snippets for this.

Run the installer and choose the "Other (Manual Setup)" option:

npx leadmagic-mcp-server install

🔑 Get Your API Key

1. 🌐 Visit LeadMagic Dashboard

2. 📝 Sign up for free (if needed)

3. 🔐 Generate your API key

4. 📋 Paste it into the interactive installer when prompted.

⚡ npx Usage (Zero Installation)

You can use the server without installing, which is great for quick tests or containerized environments:

# 🚀 Run directly with your API key
LEADMAGIC_API_KEY=your-key npx leadmagic-mcp-server

# 📋 Run the interactive installer
npx leadmagic-mcp-server install

# ❓ Check available commands
npx leadmagic-mcp-server --help
