OAPPS MCP Gateway

Internal bookkeeping automation tool for OAPPS LLC. Not for public distribution.

About this application

OAPPS MCP Gateway is a Model Context Protocol (MCP) server that lets approved AI assistants used by OAPPS LLC — e.g. Claude Desktop, Cursor, Perplexity Computer — read from and write to the company's own QuickBooks Online books.

The application is operated by OAPPS LLC for OAPPS LLC. It is not offered to, nor intended for, any third party. It is not listed on the Intuit App Store.

How it works

Authenticates to QuickBooks Online via OAuth 2.0 with the com.intuit.quickbooks.accounting scope.
Persists refresh tokens on company-owned infrastructure in a file with 0600 permissions, encrypted at rest.
Every API call goes through a token manager that auto-refreshes access tokens and rotates refresh tokens as returned by Intuit.
All mutating tool calls write a structured audit record (/var/log/quickbooks-mcp/audit.jsonl) with actor token id, tool name, parameters, and Intuit response id.
No data is sold, shared, or transmitted to any third party besides Intuit.
