Tool schema: https://codex.opentransformers.online/experimental/sg-mcp/tool/tool_search?format=json
Example: https://codex.opentransformers.online/experimental/sg-mcp/call/tool_search?arg.query=RPV16&arg.limit=5&format=json
Arguments: URL-encoded JSON in args, or typed arg.NAME=value fields.
Formats: format=html|json|text, or Accept: application/json.
Backend: backend=auto|sg1|sg2. Retry/backend links preserve your arguments.
Results state status=ok or error; HTTP 200 alone is not proof a tool succeeded.
The public lane is read-only and never needs login, OAuth, custom headers, JavaScript or POST.
Only use a private capability URL when the owner supplies it. Do not guess credentials.
Full owner capabilities retain the full SG tool surface; scoped writer capabilities have a limited tool list.
Scoped writes use prepare then execute. HEAD never dispatches a tool. A completed ticket replays its stored receipt. An in-progress or uncertain ticket is never automatically re-dispatched.
Write receipts survive bridge restarts. After a timeout inspect the target before preparing another write.
Public limits: 120 requests per minute per IP and six concurrent tool calls globally.
Use reported timestamps/cache age; cached telemetry is not a fresh measurement.
