About

npm MCP server (`billy-mcp`, Thourum) wrapping the Billy accounting API: invoice and journal-entry management, trial balance, and bank reconciliation. Write operations are gated behind explicit human-approval protection rather than being fully autonomous.

Agent Use Cases

  • 01Draft invoices or journal entries in Billy from an accounting agent, subject to human approval
  • 02Reconcile bank transactions against Billy records
  • 03Pull a trial balance for a bookkeeping review

Notes

Community MCP — not affiliated with Billy/Visma. Requires a Billy API key. Small (1 GitHub star) but actively maintained — three npm releases through July 2026. Human-approval gating on writes is a good sign but still verify before granting write scope.
