Frihet Launches Spain's First Official Open-Source MCP Server for ERP

Frihet lanza el primer servidor MCP oficial de un ERP español

Frihet has launched the first official Model Context Protocol (MCP) server for a Spanish ERP. The system exposes 31 tools across 6 resources, allowing AI assistants like Claude to manage financial data directly without manual data entry.

Why This Matters

Traditional ERP integration requires custom code and significant development investment to bridge the gap between AI assistants and business data. By implementing MCP, Frihet replaces high-friction REST API calls with a standardized conversational protocol, allowing AI models to execute business logic directly. This transition from manual API management to standardized tool-calling reduces the barrier for non-developers to automate complex financial workflows. It shifts the paradigm from mechanical automation to intelligent assistance where the software understands natural language intent.

Key Insights

• Frihet released 31 specific tools for ERP management in 2026 including invoice and expense modules.
• Model Context Protocol (MCP) was established by Anthropic as a universal standard for AI tool integration.
• The @frihet/mcp-server package enables local stdio communication for development tools like Cursor and Windsurf.
• Cloudflare Workers power the remote mcp.frihet.io implementation to support distributed teams.
• The server is released under the MIT license to ensure transparency in processing sensitive financial data.

Working Examples

Practical Applications

• Freelance designers using Claude to generate tax-compliant invoices through natural language commands. Pitfall: Missing FRIHET_API_KEY environment variables will cause authentication errors.
• Development teams querying real-time product sales data within Cursor to maintain coding context. Pitfall: Incorrect stdio configuration in IDE settings prevents the AI from discovering available tools.
