Tools

This server runs locally, so its tools are listed by your MCP client once it starts.

Environment variables

NameDescription
NEW_RELIC_LICENSE_KEY
Optional, secret		New Relic ingest license key. Optional: while NR_AI_MODE is unset or local, Preflight runs local-only with the dashboard at localhost:7777. A license key with no mode set by NR_AI_MODE or the config file makes the server fail to start.
NR_AI_MODE
Optional		Where telemetry goes: "cloud" (New Relic only), "both" (New Relic plus the local dashboard) or "local". Required when NEW_RELIC_LICENSE_KEY is set, unless the config file sets a mode. cloud turns off the local dashboard and local alerts.
NEW_RELIC_ACCOUNT_ID
Optional		New Relic account id. Required when NR_AI_MODE is cloud or both; also used for dashboard and alert deployment.
