- short-description:
- Datadog MCP + runtime observability
VKC Datadog Observability
Always pair with $vkc-repo-guardrails. For MCP connection issues, also use Cursor plugin skill ddsetup / ddconfig.
Three layers (do not confuse)
| Layer | Where | Purpose |
|-------|-------|---------|
| Cursor MCP | plugin-datadog-datadog + .cursor/settings.json | Agent queries logs/metrics/monitors without browser |
| Runtime telemetry | Vercel env | App errors/traces/metrics in Datadog org |
| Monitor contract | config/ops/datadog/monitors-contract.json | Required alert surfaces (operator creates monitors in UI) |
MCP rules
- Server id:
plugin-datadog-datadogonly (never duplicate manual~/.cursor/mcp.jsondatadog entries). - Site: US5 →
DD_MCP_DOMAIN=mcp.us5.datadoghq.com(org: infoflowpartners). - Cloud automations do not inherit local MCP OAuth — set Plugins Domain on cursor.com if cloud shows
not-setup.
Commands
npm run qa:datadog:preflight
npm run qa:monitoring:config
MONITORING_STRICT=true npm run qa:monitoring:config:strict
MCP triage sequence (interactive / automation)
- Confirm MCP connected (search dashboards or metric
datadog.mcp.session.starts). search_datadog_monitors— alert/no-data monitors.aggregate_eventsorsearch_datadog_logs— only if log indexes exist.get_datadog_metric— route/API error metrics forservice:viet-k-connect.- Append findings to
OPEN_LOOPS.md(cloud automations: REPORT ONLY).
Runtime env (Vercel / GitHub)
| Variable | Required | Default |
|----------|----------|---------|
| DD_API_KEY or DATADOG_API_KEY | yes for telemetry | — |
| DD_SITE | recommended | us5.datadoghq.com |
| DD_SERVICE | recommended | viet-k-connect |
| DD_ENV | recommended | production / preview / development |
| DD_VERSION | optional | Vercel commit sha |
| DD_MCP_DOMAIN | Cursor only | mcp.us5.datadoghq.com |
[!WARNING] Vercel APM 불가, infra-only. APM is disabled. Use Sentry + Analytics for traces.
Privacy (non-negotiable)
- Never log passport, ARC, student ID, phone, private email, raw verification evidence.
- Use
sanitizeDatadogTags()fromsrc/lib/observability/datadog-config.ts. - E2E/synthetic traffic must not pollute production dashboards.
