Buchpilot
Let Claude create invoices, contacts, and vouchers in sevDesk or Lexoffice without leaving the agent for DACH solo businesses.
Overview
Buchpilot is a MCP server for the Operate phase that connects sevDesk and Lexoffice so your agent can create invoices, contacts, and vouchers.
What is this MCP server?
- Stdio npm package buchpilot-mcp v0.1.2 with optional LEXOFFICE_API_KEY and SEVDESK_API_KEY
- Create and manage invoices, contacts, and accounting vouchers via MCP tools
- Bridges two common German SMB stacks: sevDesk and Lexoffice APIs
- Designed for DACH founders who already use cloud Buchhaltung instead of spreadsheets
- Agent-driven accounting actions without custom OAuth glue in your own repo
- Server version 0.1.2
- Two optional secret env vars: LEXOFFICE_API_KEY, SEVESK_API_KEY
- Transport: stdio via npm identifier buchpilot-mcp
What problem does it solve?
Switching between Claude and German accounting UIs slows down invoicing and contact updates when you are running the business alone.
Who is it for?
DACH solo founders already on sevDesk or Lexoffice who want agent-assisted invoice and contact workflows.
Skip if: Builders outside DACH stacks, teams on DATEV-only workflows, or anyone who needs EN 16931 e-invoice validation without those tools.
What do I get? / Deliverables
After install, your agent can perform Lexoffice and sevDesk accounting actions from one MCP session using your API keys.
- Agent-callable invoice, contact, and voucher operations against configured DACH accounting APIs
- Stdio MCP registration ready for local agent sessions

Journey fit
Bookkeeping and outgoing invoices are ongoing production work after you are shipping, not one-off build tasks. Iterate covers recurring finance ops—contacts, vouchers, and invoice drafts you adjust as clients and deals change.
How it compares
Live accounting API bridge for sevDesk/Lexoffice, not a spreadsheet expense tracker or XRechnung converter.
