  Public registry metadata endpoints (registry.npmjs.org, pypi.org, rubygems.org,
  repo1.maven.org maven-metadata.xml, api.nuget.org flat container, proxy.golang.org) plus
  api.github.com/releases/latest for agents distributed as OS packages. Cross-checked against
  https://www.elastic.co/docs/reference/apm/agents and
  https://www.elastic.co/docs/reference/opentelemetry
provider: Elastic Observability
providerId: elastic-observability
note: >-
  Elastic Observability's client surface is two generations of agent. The classic Elastic APM
  agents (elastic-apm-*, co.elastic.apm) speak the /intake/v2 event API in this repo's OpenAPI;
  the Elastic Distributions of OpenTelemetry (EDOT, co.elastic.otel / @elastic/opentelemetry-node
  / elastic-opentelemetry) speak the OTLP endpoints in the same spec. Both are first party.
  Maven Central versions were read from repo1.maven.org maven-metadata.xml because the
  search.maven.org solr index is stale (it still reported elastic-otel-javaagent 1.4.1 / 2025-04-16
  against an actual 1.12.0 / 2026-07-31).

    Last published 2025-07-01 — over a year stale. Elastic's current documented MCP surface is the
    Agent Builder MCP endpoint at {KIBANA_URL}/api/agent_builder/mcp (Stack 9.2.0+ / Serverless),
    which needs no package. Recorded as a decay signal, not as the recommended path.

    No Composer/Packagist package — repo.packagist.org returns 404 for elastic/apm-agent-php. The
    agent is a native PHP extension shipped as .deb/.rpm/.apk assets on GitHub releases, so the
    GitHub release tag is the only dated version metadata that exists.
