# X402 Industrial Intelligence — MCP Server

**The first and only MCP server for PLC (Programmable Logic Controller) intelligence.**  
Give any AI agent direct access to industrial automation data — ladder logic, tag databases, cross-references, fault root cause analysis, and sequence blockers.

## 🏭 What This Does

This MCP server connects AI agents to real industrial PLC data. It indexes **67 programs, 13,505 ladder rungs, 131,174 cross-references, and 8,534 PLC tags** across multiple controllers.

## 🔧 Tools (6 total)

| Tool | Description | Price |
|------|-------------|-------|
| `x402_plc_tag_references` | Cross-reference any PLC tag across 131K indexed locations | $0.05 |
| `x402_plc_cause_trace` | Trace upstream rungs and blocking conditions for any tag across 13K rungs | $0.50 |
| `x402_plc_fault_rca` | Fault root cause from 6.8K cause maps + 17.8K operator descriptions | $0.50 |
| `x402_start_sequence_blockers` | What is blocking a machine start sequence (560 sequence steps) | $0.50 |
