Norman Finance MCP Server is a Model Context Protocol (MCP) server that enables AI to interact with the Norman Finance API, granting access to accounting, invoices, companies, clients, taxes, documents, and more through a standardized MCP interface. The server is currently in Beta, and user feedback is encouraged via issues. A remote hosted MCP endpoint is available at https://mcp.norman.finance/sse, which uses OAuth authentication for seamless login with your Norman Finance account without handling access tokens manually. The README describes prerequisites (a Norman Finance account and ready credentials) and provides integration guidance for Cursor and Claude.ai products, including configuration details for Claude Desktop and Claude integration workflows. The server supports two authentication modes: OAuth authentication for SSE transport and environment-variable based credentials for stdio transport. Environment variables control the account credentials, environment (production or sandbox), host, port, and OAuth callback URL for remote access. Core capabilities include authentication, company management (balance and VAT insights), accounting (transactions and categorization), e-invoicing (creation, viewing, sending, recurring), client management, tax information and reports, and document attachments.
