# ATLASS OS

As of 2026-10-14.

ATLASS OS is a business operating system for field-service companies. It covers
CRM, scheduling and dispatch, estimating, invoicing, banking, accounts
payable, payroll, and double-entry books in one application.

## MCP

ATLASS OS exposes a native Model Context Protocol (MCP) server: 216 tools across
79 scopes. An AI client drives the application through that one surface, using
an access token minted inside the app and limited to the scopes it is granted.

- Business data requires authentication. Tools act only within the scopes of
  the token presented, and only on that token's business.
