Configuração por cliente MCP

Claude Desktop (stdio)

Edite claude_desktop_config.json:

{
  "mcpServers": {
    "liguelead": {
      "command": "npx",
      "args": ["-y", "@liguelead/mcp-server"],
      "env": {

      }
    }
  }
}

Claude Code

claude mcp add -s user liguelead \

  -e LIGUELEAD_APP_ID=seu-app-id \
  -e TRANSPORT=stdio \
  -- npx -y @liguelead/mcp-server

Quick start

Option 1: npx (recommended)

No installation needed — just add to your MCP client config:

{
  "mcpServers": {
    "liguelead": {
      "command": "npx",
      "args": ["-y", "@liguelead/mcp-server"],
      "env": {
        "LIGUELEAD_API_TOKEN": "your-token",
        "LIGUELEAD_APP_ID": "your-app-id",
        "TRANSPORT": "stdio"
      }
    }
  }
}

Option 2: Clone & build

git clone https://github.com/liguelead/mcp.git
cd mcp
npm install
cp .env.example .env  # Edit with your credentials
npm run build
npm start

The server starts at http://localhost:3000 by default.

Getting your credentials

1. Go to areadocliente.liguelead.app.br
2. Navigate to Integrações → API Token
3. Create an App and copy the API Token and App ID

Client configuration

Claude Desktop (stdio)

Edit claude_desktop_config.json:

{
  "mcpServers": {
    "liguelead": {
      "command": "npx",
      "args": ["-y", "@liguelead/mcp-server"],
      "env": {
        "LIGUELEAD_API_TOKEN": "your-token",
        "LIGUELEAD_APP_ID": "your-app-id",
        "TRANSPORT": "stdio"
      }
    }
  }
}

Claude Code

claude mcp add -s user liguelead \
  -e LIGUELEAD_API_TOKEN=your-token \
  -e LIGUELEAD_APP_ID=your-app-id \
  -e TRANSPORT=stdio \
  -- npx -y @liguelead/mcp-server

Cursor / Windsurf

Add to your MCP settings with the same configuration as Claude Desktop above.

Remote HTTP server

Any MCP client that supports Streamable HTTP can connect via:

POST https://your-server.com/mcp

Credentials stay on the server — the client doesn't need them.

mcp-remote bridge

For clients that don't support HTTP natively (e.g., Claude Desktop connecting to a remote server):

{
  "mcpServers": {
    "liguelead": {
      "command": "npx",
      "args": ["mcp-remote", "https://your-server.com/mcp"]
    }
  }
}

Deploy

Docker

docker build -t liguelead-mcp .
docker run -d -p 3000:3000 \
  -e LIGUELEAD_API_TOKEN=your-token \
  -e LIGUELEAD_APP_ID=your-app-id \
  liguelead-mcp

Railway / Render

1. Connect the Git repository
2. Set environment variables: LIGUELEAD_API_TOKEN, LIGUELEAD_APP_ID
