toolhive-registry-server

Provides a standards-compliant MCP Registry Server with a central registry catalog and an Admin API for managing sources/registries/entries. It supports multiple backend data sources (API/Git/File/Managed/Kubernetes) and optional PostgreSQL storage, with OAuth/OIDC-based enterprise auth support.

Best When

You need an internal/external governance layer for MCP registries, with OAuth/OIDC security and support for multiple registry data sources (including Git/file and optional DB).

Avoid When

You cannot provide network-level security (HTTPS) or you need a simpler unauthenticated public registry without governance features.

Use Cases

  • Centralized discovery and governance of MCP servers and tool/skill metadata
  • Federating multiple MCP registry backends (upstream, internal Git/File, managed/custom, and Kubernetes discovery) into a unified catalog
  • Enterprise administration of registry sources and published entries with auditability
  • Integrating MCP clients with a single registry endpoint that implements the MCP Registry API v0.1

Not For

  • A lightweight, no-auth internal service with minimal operational overhead (it’s enterprise-oriented and may require DB/OIDC setup)
  • A real-time registry of highly dynamic tool availability where only on-demand sources aren’t sufficient
  • Workloads needing streaming/webhook event delivery rather than pull-based REST APIs

README indicates OAuth/OIDC with roles such as manageSources/manageRegistries/manageEntries for Admin API write operations; exact scope names and token claims are not fully detailed in the provided excerpt.

Known Gotchas

  • Admin endpoints require appropriate roles (manageSources/manageRegistries/manageEntries). Agents without auth/roles may receive authorization failures.
  • Some data sources are on-demand (Managed/Kubernetes) rather than continuously synced, so results may differ from expectations during or immediately after startup.
  • Pagination behavior for list endpoints is not described in the provided excerpt; agents should not assume cursor-based pagination support without checking the full API reference.
