## Documentation

## What the ATLASS OS MCP server does

The ATLASS OS MCP server provides 58 tools covering three areas: field-service CRM, scheduling, and double-entry accounting. It is intended for agents that need to work across operational and financial workflows through the Model Context Protocol.

The available description identifies the tool categories but does not list individual tool names or define the exact actions each tool supports. As a result, the documented scope is broad rather than a detailed action-by-action reference. Developers evaluating it should confirm the available tools and their parameters through the hosted service before building an agent workflow around a specific operation.

## How it works

ATLASS OS is hosted and is used with a bring-your-own-agent model. In practice, the agent is supplied by the user, while ATLASS OS provides the MCP-accessible tools for the supported CRM, scheduling, and accounting domains. The supplied material does not identify a local package, runtime, database, or deployment process for running the service yourself.

The published source is `https://app.atlass-os.com/mcp`. The available information does not specify whether this address should be configured as a particular MCP transport, nor does it document authentication or account requirements. Those details should be checked in the service's current configuration instructions.

## Setup and configuration

Use the hosted ATLASS OS service with an MCP-compatible agent rather than expecting a local installation. The listing does not provide environment variables, command-line steps, configuration examples, or client-specific instructions. It also does not state which agent clients have been tested.

Before adoption, verify the connection format required by the hosted URL, how credentials are supplied, and whether access to all 58 tools depends on an account or plan. None of those conditions are described in the available material.

## Tools and capabilities

The documented capabilities are:

- Field-service CRM tools
- Scheduling tools
- Double-entry accounting tools
- A total of 58 MCP tools across those areas

These categories may suit an agent that needs to combine service operations, scheduling work, and accounting workflows. The description does not provide schemas, required inputs, return formats, permissions, or examples, so individual tool behavior cannot be specified here.

## Limitations and notes

The ATLASS OS MCP server has limited public documentation in the supplied material. There is no README, tool catalog, authentication guide, compatibility matrix, license information, or statement of data-handling behavior. The listing also does not clarify whether the tools only retrieve information, make changes, or support both types of operation.

Treat the 58-tool count and three domain categories as the confirmed scope. Confirm write behavior, access controls, supported clients, and operational limits before connecting the server to production CRM or accounting workflows.
