MCP server for Trane Technologies Tracer SC+ Building Automation System (BAS) API.

Overview

This MCP server provides AI agents with read access to Trane Tracer SC+ building automation systems. It wraps the Tracer SC+ API Builder surface to enable inventory and telemetry retrieval for buildings, equipment, BACnet points, alarms, schedules, and trend logs.

Tracer SC+ is a self-hosted building automation controller from Trane Technologies. This server connects to a customer's deployment and exposes 8 tools for agent-based BAS operations.

Related MCP server: @inscada/mcp-server

Features

  • Read-only by default - All tools are read operations that do not modify HVAC behavior

  • 8 BAS tools - Buildings, equipment, points, alarms, schedules, and trends

  • Setpoint writes gated - Requires explicit TRANE_ALLOW_SETPOINT_WRITE=true env var

  • Async httpx client - Non-blocking API calls with 60s timeout

  • Pydantic v2 schemas - Type-safe inputs and outputs

  • SSL verification toggle - Supports self-signed dev certificates

Installation

Available Tools

8 tools
get_equipmentA

Get full metadata for a single equipment unit including current health flags, model, and linked points.

Inputs: equipment_id (required).

list_alarmsB

List active alarms across the operator's Tracer SC+ deployment. Used by an on-call agent triaging what is unhealthy.

Inputs: status, limit.

list_buildingsA

List buildings managed by the operator's Trane Tracer SC+ instance. Standard read path for an agent that needs to enumerate the BAS surface.

Inputs: no named parameters.

list_equipmentA

List HVAC equipment at a building (AHUs, chillers, boilers, VAV boxes, fan coils, etc.). Used by an agent scoping work for a building.

Inputs: building_id (required).

list_schedulesB

Inventory operating schedules for buildings + equipment. Used by an agent planning around occupancy or seasonal modes.

Inputs: limit.

read_pointB

Read the current value of a BACnet point on equipment (e.g. supply-air temperature, zone setpoint, damper position). Standard read path for live BAS state.

Inputs: equipment_id (required), point_name (required).

set_setpointA

Write a new setpoint value to equipment. Gated by TRANE_ALLOW_SETPOINT_WRITE=true because writes change real HVAC behavior in real buildings. The MCP refuses unless the operator has explicitly authorized writes.

Inputs: equipment_id (required), point_name (required), value (required).

    A3.7/5.0

    Scored across 8 tools

    Disambiguation5/5

    Each tool targets a distinct resource or action: equipment metadata, alarms, buildings, equipment list, schedules, trends, point read, setpoint write. No overlapping purposes.

    Naming Consistency5/5

    All tools follow a consistent verb_noun pattern in snake_case (get_, list_, read_, set_). No mixing of conventions.

    Tool Count5/5

    8 tools are well-scoped for a HVAC building management server, covering inventory, alarms, live data, and control without being excessive.

    Completeness4/5

    Covers monitoring and basic control (setpoint write) but lacks operations like schedule modification or alarm acknowledgment, which are minor gaps for the typical use case.
