Best for
  • DevOps teams looking to integrate Prometheus metric querying into AI workflows.
  • Users who want to query metrics directly in MCP clients like Claude Desktop.
  • Scenarios requiring lightweight deployment via Docker or Helm.
  • Developers auditing NPM dependencies within AI workflows
  • Teams performing supply chain security assessments
  • Users of Claude Desktop, Cursor, or VS Code
Not for
  • Users without Prometheus or MCP needs.
  • Organizations requiring official support or strict certification (this server is community-maintained).
  • High-throughput batch data extraction with low latency requirements (MCP interaction may not be suitable).
  • Projects outside the NPM ecosystem (e.g., pure Python/Go)
  • Environments without network access to deps.dev, OSV.dev, and the npm registry
  • Scenarios requiring maintenance by an official upstream vendor
Required permissions
  • Network access to the Prometheus server specified by PROMETHEUS_URL.
  • Authentication credentials if Prometheus requires them (username/password or token).
  • Ability to send custom headers via PROMETHEUS_CUSTOM_HEADERS.
  • If using TLS, certificate files or SSL verification settings.
  • Network access to the NPM registry and external services (deps.dev, OSV.dev, OpenSSF, npms.io, GitHub)
  • Read access to workspace lockfiles (pnpm-lock.yaml, package-lock., yarn.lock) for cache invalidation
Risks and side effects
  • Exposing Prometheus query endpoints could increase data leakage risk; ensure network access is restricted.
  • Queries may hang if timeout is not set, but the server has a default 30-second timeout.
  • Incorrect configuration can lead to authentication failures or connection errors.
  • May consume significant context tokens in MCP clients; disabling links can mitigate.
  • Third-party READMEs and changelogs are untrusted external content; they are wrapped in tags with _meta flags but should still be handled cautiously
  • Depends on availability and accuracy of external services
  • Batch requests are capped at 25 packages to prevent registry enumeration; larger sets require batching
  • Third-party open source project, not officially maintained by NPM or Anthropic
