Prerequisites

Before using this MCP server, you need to:

• Create an account on Norman Finance
• Have your email and password ready for authentication

Remote MCP Server

Norman now offers a hosted remote MCP server at:

https://mcp.norman.finance/sse

The remote MCP is recommended because it utilizes OAuth authentication, enabling you to log in directly with your Norman account without the need to create or manage access tokens manually.

Configuration

Authentication Methods

The Norman MCP server supports two authentication methods:

1. OAuth Authentication (for SSE transport)

When using the server with MCP Inspector, Claude, or other SSE clients, the server uses OAuth 2.0 authentication:

• Start the server with SSE transport:

  python -m norman_mcp --transport sse
  

• When connecting to the server, you'll be directed to a login page

• Enter your Norman Finance credentials

• You'll be redirected back to your application with authentication tokens

2. Environment Variables (for stdio transport)

When using the server with Claude Desktop or stdin/stdout communication, provide credentials through environment variables:

# .env
NORMAN_EMAIL=[e-mail]
NORMAN_PASSWORD=your-password
NORMAN_ENVIRONMENT=production  # or "sandbox" for the development environment
NORMAN_API_TIMEOUT=200  # Request timeout in seconds

Environment Variables

The server can be configured using these environment variables:

# Authentication (for stdio transport)
NORMAN_EMAIL=[e-mail]
NORMAN_PASSWORD=your-password
NORMAN_ENVIRONMENT=production  # or "sandbox" for the development environment

# Server configuration
NORMAN_MCP_HOST=0.0.0.0  # Host to bind to
NORMAN_MCP_PORT=3001     # Port to bind to
NORMAN_MCP_PUBLIC_URL=http://example.com  # Public URL for OAuth callbacks (important for remote access)
NORMAN_API_TIMEOUT=200   # Request timeout in seconds
