Middleman MCP

Security proxy for enterprise integrations for LLMs using the Model Context Protocol (MCP).

Installation & Configuration

1. Add to Cursor's MCP Settings

Add the following configuration to your Cursor MCP settings file:

{
  "mcpServers": {
    "middleman": {
      "command": "npx",
      "args": ["@trymiddleman/mcp"]
    }
  }
}

2. With API Key

If you have an API key, you can pass it as an argument:

{
  "mcpServers": {
    "middleman": {
      "command": "npx",
      "args": ["@trymiddleman/mcp", "YOUR_API_KEY"]
    }
  }
}

Authentication

On first run without an API key, Middleman will:

1. Start a local authentication server
2. Open your browser for authentication
3. Store your credentials securely for future use

Features

Middleman acts as a security proxy between your LLM applications and enterprise services, providing:

• Secure credential management
• Enterprise integration capabilities
• MCP-compliant server implementation
• Seamless authentication flow

Requirements

• Node.js >= 20
• Cursor IDE with MCP support

Troubleshooting

Clear Stored Credentials

If you need to reset your authentication:

npx @trymiddleman/mcp clear-credentials

Or run the clear credentials script directly:

node node_modules/@trymiddleman/mcp/dist/scripts/clear-credentials.js
