About tracehub-mcp
tracehub-mcp is an MCP server published by the GitHub account mcpsmiths. Query OTel traces across Jaeger, Tempo, Traceloop, Datadog, Sentry, X-Ray, New Relic, Honeycomb.
It runs on your own machine: your AI client starts it from the PyPI package tracehub-mcp at version 0.13.0.
It asks for 2 secrets: BACKEND_API_KEY and BACKEND_APP_KEY. Give it a key with the least access that still works.
It also needs BACKEND_TYPE and BACKEND_URL set before it starts.
Version 0.13.0 was published on 14 October 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 0 warn, 0 fail, 2 info. How we check.
What it asks for
| Variable | Required | Secret | Description |
|---|---|---|---|
BACKEND_TYPE | Yes | No | Which observability backend to query. |
BACKEND_URL | Yes | No | 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 dereferenced for a live request. |
BACKEND_API_KEY | No | Yes | 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 | No | No | 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 | No | No | 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 | No | No | Honeycomb dataset slug, required for the Honeycomb backend only - the Query Data API is dataset-scoped. |
BACKEND_APP_KEY | No | Yes | Datadog Application key, required in addition to BACKEND_API_KEY for the Datadog backend only. |
BACKEND_TEMPO_INSTANCE_ID | No | No | 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 | No | No | Sentry organization slug, required for the Sentry backend only. |
BACKEND_SENTRY_PROJECT | No | No | Sentry project slug, optional for the Sentry backend - narrows queries to one project. |
BACKEND_ENVIRONMENTS | No | No | Comma-separated environments for the Traceloop backend only. |
BACKEND_TIMEOUT | No | No | Request timeout in seconds. |
BACKEND_MAX_RESPONSE_BYTES | No | No | 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 | No | No | Logging level. |
MAX_TRACES_PER_QUERY | No | No | Maximum traces validated per query (1-1000). |
SLOW_REQUEST_THRESHOLD_MS | No | No | Logs a WARNING for any backend request slower than this, independent of LOG_LEVEL. Unset disables slow-request logging. |
QUERY_CACHE_TTL_SECONDS | No | No | 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 | No | No | 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 | No | No | 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 | No | No | Service name reported in self-instrumentation spans, only used when OTEL_EXPORTER_OTLP_ENDPOINT is set. |
MCP_INCLUDE_ARGS_IN_SPANS | No | No | Include tool call arguments/results as OTel span attributes when self-instrumentation is enabled. Off by default since they may contain sensitive data. |
