Environment variables

NameDescription
BACKEND_TYPE
Required		Which observability backend to query.
BACKEND_URL
Required		Backend API endpoint, e.g. http://localhost:16686 for Jaeger, https://api.datadoghq.com for Datadog, https://api.newrelic.com/graphql for New Relic, or https://api.honeycomb.io for Honeycomb. For the X-Ray backend this is decorative only (e.g. https://xray.us-east-1.amazonaws.com) - never dereferen…
BACKEND_API_KEY
Optional, secret		API key or auth token. Required for Traceloop, Datadog, Sentry, New Relic, and Honeycomb; not used by Jaeger, Tempo, or X-Ray. For New Relic this must be a User API key, not an Ingest or License key; for Honeycomb this must be a Configuration Key, not an Ingest or Management key.
BACKEND_AWS_REGION
Optional		AWS region, e.g. us-east-1. Required for the X-Ray backend only - X-Ray authenticates via boto3's standard AWS credential chain, not BACKEND_API_KEY.
BACKEND_NEWRELIC_ACCOUNT_ID
Optional		New Relic account ID, required for the New Relic backend only - NerdGraph queries are user-scoped, not account-scoped, so this identifies which account's data to read.
BACKEND_HONEYCOMB_DATASET
Optional		Honeycomb dataset slug, required for the Honeycomb backend only - the Query Data API is dataset-scoped.
BACKEND_APP_KEY
Optional, secret		Datadog Application key, required in addition to BACKEND_API_KEY for the Datadog backend only.
BACKEND_TEMPO_INSTANCE_ID
Optional		Grafana Cloud stack/instance ID, used with BACKEND_API_KEY for Basic Auth (Tempo backend only, required for Grafana Cloud-hosted Tempo, not needed for self-hosted Tempo).
BACKEND_SENTRY_ORG
Optional		Sentry organization slug, required for the Sentry backend only.
BACKEND_SENTRY_PROJECT
Optional		Sentry project slug, optional for the Sentry backend - narrows queries to one project.
BACKEND_ENVIRONMENTS
Optional		Comma-separated environments for the Traceloop backend only.
BACKEND_TIMEOUT
Optional		Request timeout in seconds.
BACKEND_MAX_RESPONSE_BYTES
Optional		Ceiling on the decoded size of any single backend response, in bytes (1 to 1073741824). An oversized body is refused before it is buffered or parsed.
LOG_LEVEL
Optional		Logging level.
MAX_TRACES_PER_QUERY
Optional		Maximum traces validated per query (1-1000).
SLOW_REQUEST_THRESHOLD_MS
Optional		Logs a WARNING for any backend request slower than this, independent of LOG_LEVEL. Unset disables slow-request logging.
QUERY_CACHE_TTL_SECONDS
Optional		Cache backend query results for this many seconds with in-flight request coalescing; finite, > 0 and at most 86400 (one day). Unset disables the cache.
QUERY_CACHE_MAX_ENTRIES
Optional		Upper bound on the number of cached query results held at once (1-100000); the least-recently-used entry is evicted first.
OTEL_EXPORTER_OTLP_ENDPOINT
Optional		Enables opt-in OTel self-instrumentation of tool calls when set. Unset means zero overhead - no TracerProvider is configured and no middleware is registered.
OTEL_SERVICE_NAME
Optional		Service name reported in self-instrumentation spans, only used when OTEL_EXPORTER_OTLP_ENDPOINT is set.
MCP_INCLUDE_ARGS_IN_SPANS
Optional		Include tool call arguments/results as OTel span attributes when self-instrumentation is enabled. Off by default since they may contain sensitive data.
