Quick Start

Prerequisites

• Node.js >= 20
• QuickBooks Online OAuth2 app credentials (requires an Intuit developer account)

Install and Build

npm install
npm run build

Run (stdio mode)

QBO_ACCESS_TOKEN=your-access-token QBO_REALM_ID=your-realm-id npm start

Run (HTTP mode)

MCP_TRANSPORT=http QBO_ACCESS_TOKEN=your-access-token QBO_REALM_ID=your-realm-id npm start

The server listens on http://0.0.0.0:8080/mcp by default.

Docker

docker build -t qbo-mcp .
docker run -p 8080:8080 \
  -e MCP_TRANSPORT=http \
  -e QBO_ACCESS_TOKEN=your-access-token \
  -e QBO_REALM_ID=your-realm-id \
  qbo-mcp

Environment Variables

Variable	Required	Default	Description
QBO_ACCESS_TOKEN	Yes (env mode)	—	QuickBooks Online OAuth2 access token
QBO_REALM_ID	Yes (env mode)	—	QuickBooks Online company (realm) ID
MCP_TRANSPORT	No	stdio	Transport type: stdio or http
MCP_HTTP_PORT	No	8080	HTTP server port
MCP_HTTP_HOST	No	0.0.0.0	HTTP server bind address
AUTH_MODE	No	env	Auth mode: env or gateway

Gateway Mode

When AUTH_MODE=gateway, credentials are passed per-request via HTTP headers instead of environment variables:

• X-Qbo-Access-Token — OAuth2 access token
• X-Qbo-Realm-Id — QuickBooks Online company (realm) ID

This allows a gateway/proxy to manage multi-tenant credentials.
