Indautomation

RepairXpert/indautomation MCP server

AI-powered equipment diagnosis. This repo ships TWO MCP servers — one for industrial automation, and an automotive OBD-II MCP server with a built-in expert DTC database (probable causes, ranked fix steps, field tricks) — the first OBD MCP server focused on repair knowledge rather than raw PID passthrough.

MCP Servers

1. Industrial Automation (mcp_server.py)

Fault diagnosis for Allen-Bradley PLCs, conveyors, pilers, AS/RS, packaging lines, palletizers, VFDs, and CR30 relays.

Tool	Description
diagnose_fault	AI fault diagnosis from symptoms or error codes
search_parts	Search replacement parts catalog (AutomationDirect, Grainger, Amazon)
get_equipment_profile	Equipment specs, components, maintenance history
list_fault_codes	Browse 313+ fault codes by category
get_allen_bradley_fault	Rockwell-specific fault lookup
list_supported_equipment	All supported equipment types and brands
get_maintenance_checklist	Preventive maintenance schedules
get_parts_for_fault	Parts needed to fix a specific code

Coverage: 313 fault codes — 52 general industrial, 51 Allen-Bradley/Rockwell, 26 conveyors, 21 VFDs, 18 packaging, 11 AS/RS, 8 palletizers, 7 pilers, 7 CR30.

2. Automotive OBD-II (obd_mcp_server.py) — OBD MCP with Expert Diagnosis

Vehicle diagnostics via OBD-II. Works in mock mode out of the box (no hardware needed) or real mode with any ELM327 adapter (serial or Bluetooth).

Tool	Description
read_dtcs	Read stored and pending diagnostic trouble codes
clear_dtcs	Clear DTCs and reset MIL (Check Engine Light)
get_vehicle_info	VIN, ECU name, calibration IDs, OBD protocol (Mode 09)
read_pid	Live sensor data: RPM, coolant temp, MAF, fuel trims, O2, etc.
get_freeze_frame	Sensor snapshot captured at time of fault
diagnose_dtc	Expert diagnosis: probable causes, fix steps, field tricks

Coverage: 106 automotive DTCs — P0xxx generic powertrain, P1xxx/P2xxx manufacturer-specific (Ford, GM, Toyota, Honda), B/C/U body/chassis/network codes.

Modes:

• OBD_MODE=mock (default) — realistic test data, no hardware
• OBD_MODE=real — uses python-obd with ELM327 adapter (OBD_PORT=COM3 or /dev/ttyUSB0)

Quick Start

Add to your MCP client config (e.g. ~/.claude/.mcp.json):

{
  "mcpServers": {
    "repairxpert-indauto": {
      "command": "python",
      "args": ["C:/RepairXpertIndAutomation/mcp_server.py"]
    },
    "repairxpert-obd": {
      "command": "python",
      "args": ["C:/RepairXpertIndAutomation/obd_mcp_server.py"],
      "env": {
        "OBD_MODE": "mock"
      }
    }
  }
}

Restart your MCP client and both servers' tools will be available to the agent.

Requirements

• Python 3.11+
• Industrial: pip install -r requirements.txt
• Automotive (real mode only): pip install obd

Docker

docker build -t repairxpert-indauto .
docker run -p 8300:8300 repairxpert-indauto

Why This Matters

• Industrial MCP: Real Allen-Bradley/Rockwell fault coverage that no general-purpose MCP server has.
• Automotive OBD MCP: Unlike raw-PID OBD bridges, this one ships a curated expert database with probable causes and ranked fix steps so agents give actionable repair guidance, not just sensor numbers. Mock mode lets developers build against it without owning an ELM327 adapter.

Built by a working field tech, not a vendor.

Hosted Service

A hosted version of IndAutomation runs at indautomation.onrender.com with a web UI, REST API, and the same diagnostic engine the MCP servers expose.

Pricing (hosted)

Plan	Price	Includes
Free	$0	Try the diagnostic engine, limited queries
Pro	$19/mo	Unlimited diagnoses, parts search, fault history
Enterprise	$49/mo	Multi-user, priority support, custom equipment profiles

Billing is handled by Stripe. The MCP servers in this repo are free and open source — the hosted tier only exists for teams that want a managed web UI and shared history.
