Best for
  • Developers building AI assistants or agents that need to integrate with Mastercard Developers APIs.
  • Teams looking for quick access to Mastercard API documentation within their development environment.
  • Developers auditing NPM dependencies within AI workflows
  • Teams performing supply chain security assessments
  • Users of Claude Desktop, Cursor, or VS Code
Not for
  • Not suitable for users needing actual API calls or transactions; this server only provides information retrieval.
  • Not for generic documentation searches unrelated to Mastercard Developers.
  • 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
  • No authentication or API keys required for the server itself, as it accesses only public documentation and API specifications.
  • Client requires ability to execute `npx` command.
  • 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
  • Documentation and API specs may not be the most up-to-date since information comes from the public developer portal.
  • Dependent on network connectivity; server may not work if Mastercard developer portal is unreachable.
  • As a third-party extension, there could be undiscovered bugs or limitations.
  • 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
