Overview

Read-only CLI and MCP server for tracing GX Works3 ladder logic without opening GX Works3. It lets a human or an AI agent inspect program state and reason about why a coil never turns on.

Best for

Best for
Maintenance engineers and AI agents who need quick, safe visibility into GX Works3 ladder logic.

Use cases

• Trace coil activation paths in GX Works3 projects
• Debug why an output stays off using an AI agent
• Query ladder logic from a CI or automation script

Use cases

• Trace coil activation paths in GX Works3 projects
• Debug why an output stays off using an AI agent
• Query ladder logic from a CI or automation script

Pros

• Read-only design avoids accidental program changes
• CLI and MCP interfaces support both manual and agent-driven use
• Eliminates the need to launch GX Works3 for basic tracing

Cons

• Very early project with only 1 star, so maturity is unproven
• Python runtime and dependencies required
• Limited to tracing and diagnostics, no write or edit capability
