Installation

npm install -g @seven.io/mcp

Authentication

This MCP server supports two authentication methods:

Option 1: OAuth 2.0 with PKCE (Recommended)

OAuth provides better security with automatic token refresh and fine-grained scopes.

1. Login via CLI:

npx @seven.io/mcp login

This will:

• Open your browser to seven.io OAuth authorization

• Request necessary permissions (SMS, Voice, RCS, etc.)

• Store tokens securely in your system keychain

• Auto-refresh tokens when they expire

CLI Commands:

# Login with OAuth
npx @seven.io/mcp login

# Check authentication status
npx @seven.io/mcp status

# Logout (remove stored tokens)
npx @seven.io/mcp logout

Option 2: API Key (Legacy)

For backwards compatibility, you can still use an API key:

export SEVEN_API_KEY="your-api-key"

Get your API key from the seven.io dashboard.

Priority

If both authentication methods are configured, OAuth takes priority.

Usage with Claude Desktop

Add this to your Claude Desktop configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

Windows: %APPDATA%\Claude\claude_desktop_config.json

Linux: ~/.config/Claude/claude_desktop_config.json

With OAuth (recommended):

{
  "mcpServers": {
    "seven": {
      "command": "npx",
      "args": ["@seven.io/mcp"]
    }
  }
}

With API Key:

{
  "mcpServers": {
    "seven": {
      "command": "npx",
      "args": ["@seven.io/mcp"],
      "env": {
        "SEVEN_API_KEY": "your-api-key"
      }
    }
  }
}

With Debug Logging: To enable request/response logging for debugging, add the SEVEN_LOG_FILE environment variable:

{
  "mcpServers": {
    "seven": {
      "command": "npx",
      "args": ["@seven.io/mcp"],
      "env": {
        "SEVEN_API_KEY": "your-api-key",
        "SEVEN_LOG_FILE": "/tmp/mcp-seven-debug.log"
      }
    }
  }
}

Then monitor the log file:

tail -f /tmp/mcp-seven-debug.log

Note: If using OAuth, run npx @seven.io/mcp login before starting Claude Desktop.

Endpoint Validation

To run endpoint validation tests that verify the API paths are correct:

SEVEN_API_KEY=your-api-key npm test

These integration tests ensure that endpoints match the seven.io API documentation and will catch issues like incorrect paths (e.g., using /logbook/received instead of /journal/inbound).
