Environment variables

BACKEND_TYPErequiredWhich observability backend to query.
BACKEND_URLrequiredBackend 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 dereferenced for a live request.
BACKEND_API_KEYsecretAPI 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_APP_KEYsecretDatadog Application key, required in addition to BACKEND_API_KEY for the Datadog backend only.
BACKEND_ENVIRONMENTSComma-separated environments for the Traceloop backend only.
BACKEND_TIMEOUTRequest timeout in seconds.
BACKEND_MAX_RESPONSE_BYTESCeiling 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_LEVELLogging level.
MAX_TRACES_PER_QUERYMaximum traces validated per query (1-1000).
QUERY_CACHE_MAX_ENTRIESUpper bound on the number of cached query results held at once (1-100000); the least-recently-used entry is evicted first.
OTEL_SERVICE_NAMEService name reported in self-instrumentation spans, only used when OTEL_EXPORTER_OTLP_ENDPOINT is set.
MCP_INCLUDE_ARGS_IN_SPANSInclude tool call arguments/results as OTel span attributes when self-instrumentation is enabled. Off by default since they may contain sensitive data.

A starting point — check the repository for exact arguments and setup. Restart your client after editing the config.
