Fakturai MCP MCP server

Fakturai provides an official hosted MCP server for generating and validating German B2B e-invoices. It supports ZUGFeRD, Factur-X, and XRechnung standards, ensuring compliance with EN 16931 and KoSIT validation before delivery. The server allows agents to create structured invoices, validate existing documents, and check compliance status via tools like generate_einvoice and validate_einvoice.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http fakturai-mcp https://fakturai.de/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add fakturai-mcp --url https://fakturai.de/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable fakturai-mcp in your MCP settings.

  "mcpServers": {
    "fakturai-mcp": {
      "url": "https://fakturai.de/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.

Cline configuration

{
  "mcpServers": {
    "fakturai-mcp": {
      "type": "streamableHttp",
      "url": "https://fakturai.de/mcp",
      "disabled": false
