Environment variables

Defined in the server's official registry manifest. Required secrets are shown as <YOUR_…> placeholders in the configs above.

TRANSPORT required — MCP transport. Fixed to stdio for this package.
WAGO_PLC_HOSTS required — Comma-separated IPs of the WAGO PLCs, reachable from this machine
DEFAULT_PLC_USERNAME required — WBM username on the PLCs
DEFAULT_PLC_PASSWORD required secret — WBM password, same on all listed PLCs
WAGO_TIMEOUT_SECONDS — WDA request timeout. CC100 needs 45 or more, other controllers work with 15
WAGO_ALLOW_WRITES required — true lets the agent change parameters, run methods and upload files. Anything else keeps every PLC read-only
AUDIT_LOG_FILE — Optional path for the tamper-evident audit log of writes and refusals
