Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| pingA | Health check — verify the server is running. |
| correlate_projectsA | Build a full correlation map between an Ignition project and an L5X PLC project. Walks all Ignition OPC tags, maps each to its L5X counterpart via OPC item path normalization, and returns matched pairs plus unmatched tags on both sides. Args: ignition_path: Path to Ignition project directory or .zip export. l5x_path: Path to Studio 5000 .l5x file. mapping_file: Optional JSON file with explicit tag mappings (overrides convention). |
| trace_tagA | Trace a single tag end-to-end: Ignition config → OPC path → L5X tag → PLC logic. Returns the complete signal chain showing where the tag is defined in Ignition, what PLC tag it maps to, and every rung/line of PLC logic that references it. Args: ignition_path: Path to Ignition project directory or .zip export. l5x_path: Path to Studio 5000 .l5x file. tag_name: Ignition tag name to trace (e.g. "Running", "Conveyors/Line1/Speed"). mapping_file: Optional JSON file with explicit tag mappings. |
| find_unmapped_tagsA | Find tags that exist on one side but not the other — commissioning gap analysis. Returns Ignition OPC tags with no L5X match and L5X tags with no Ignition reference. Args: ignition_path: Path to Ignition project directory or .zip export. l5x_path: Path to Studio 5000 .l5x file. mapping_file: Optional JSON file with explicit tag mappings. |

Scored across 4 tools
correlate_projects and find_unmapped_tags substantially overlap: the former already returns unmatched tags on both sides, making the latter a redundant subset. ping and trace_tag are distinct, but the boundary between the two correlation tools is unclear.
The three main tools follow a clear verb_noun snake_case pattern (correlate_projects, trace_tag, find_unmapped_tags). ping breaks the pattern slightly, but it is a standard health-check name and does not cause confusion.
Four tools is well-scoped for a specialized Ignition-to-L5X bridging server. Each tool addresses a distinct high-level need: health verification, full correlation, single-tag tracing, and gap analysis.
The server covers the primary domain workflows: full project correlation, deep single-tag tracing, and commissioning gap analysis. It lacks explicit export/write functionality for generated mappings, but agents can work around this since the returned data is structured.
