Security ⚠️

IMPORTANT: TWITTER CREDENTIAL PROTECTION

This MCP server requires Twitter credentials to operate. To protect these sensitive credentials:

1. NEVER share your credentials
2. NEVER run commands that display your credentials
3. NEVER allow the LLM to execute shell commands directly without your approval

Multiple Layers of Protection

This server implements several layers of security to keep your credentials safe:

1. Credential Isolation

• Your credentials are only loaded during initialization
• After loading, credentials are immediately removed from environment variables
• Credentials are never logged or transmitted to the LLM

2. Memory Protection

• Secure memory allocation using sodium-native
• Memory locking to prevent swapping to disk
• Zero-out memory buffers after use

3. Access Prevention

• Secure environment variable handling
• Strict validation of required environment variables
• Console output sanitization to prevent leaking secrets

Setup

1. Clone the repository
2. Install dependencies:

   npm install

3. Build the project:

   npm run build

Required Environment Variables

The Twitter Client MCP requires the following environment variables:

TWITTER_USERNAME=your_username
TWITTER_PASSWORD=your_password

Optionally, you can add Twitter API v2 credentials for advanced functionality:

TWITTER_API_SECRET_KEY=your_api_secret
TWITTER_ACCESS_TOKEN=your_access_token
TWITTER_ACCESS_TOKEN_SECRET=your_access_secret

      "command": "npx",
      "args": [
        "-y",
        "github:mzkrasner/twitter-client-mcp"

    }
  }
}

Development

Important Note for Development

When developing the MCP server, use console.error() instead of console.log() for all debugging and logging statements. The MCP protocol communicates with the client via stdout, so any console.log() statements will interfere with this communication.
