## Tools (as reported by the server, not verified)

- `audit\_nodeset\_compatibility`: Compare two complete OPC UA NodeSet2 XML documents when both fit in a single request. Pass old\_nodeset\_xml as the full baseline revision and new\_nodeset\_xml as the full candidate revision. The deterministic report returns result \(COMPATIBLE, REVIEW\_REQUIRED, BREAKING, or INSUFFICIENT\_INPUT\), old\_nod
- `nodeset\_compatibility\_status`: Return bounded service metadata for OPC UA NodeSet Compatibility Gate. Use this only to discover deployment stage, deterministic static-analysis scope, production availability and payment status; do not use it to compare NodeSets. The result includes the shared MCP endpoint and explicitly lists whic
- `begin\_nodeset\_upload`: Start one temporary in-memory upload for a large NodeSet2 XML document. Call this once for the old baseline and once for the new candidate when the complete XML documents are too large for audit\_nodeset\_compatibility. It returns upload\_id and max\_total\_chars. Append that document's chunks in origina
- `append\_nodeset\_chunk`: Append the next unmodified text chunk to a temporary NodeSet2 upload created by begin\_nodeset\_upload. Pass upload\_id exactly as returned by begin\_nodeset\_upload and chunk as the next consecutive XML text segment; send every chunk in original order without overlap, omission or reformatting. On succes
- `audit\_uploaded\_nodesets`: Compare two large NodeSet2 XML revisions after both have been fully staged with begin\_nodeset\_upload and append\_nodeset\_chunk. Pass old\_upload\_id for the baseline revision and new\_upload\_id for the candidate revision. This call consumes both upload IDs, so do not reuse them afterward. The report has
