Model Context ProtocolOrganization

Model Context Protocol

@modelcontextprotocol • An open protocol that enables seamless integration between LLM applications and external data sources and tools.. Use this route to separate flagship concentration from portfolio breadth before you treat a publisher as broadly strong.

Why this rank

This organization stands out because its public portfolio is relatively balanced across 30 repositories.

Balanced portfolio across 30 reposTop 3 share 55%

Organization pages work best when you separate portfolio breadth from flagship concentration. In Model Context Protocol's case, the visible top three repositories account for about 55% of total stars in this snapshot, which helps explain whether the organization is known for one breakout project or for a broader repeatable portfolio.

The dominant language mix here is TypeScript (9), Unknown (7), Go (3). That makes this page useful not just for popularity checks, but also for seeing what technical shape an organization's public ecosystem actually has.

Source: GitHub API fallback. This is the same cache-first snapshot used by the organization ranking list, so the summary view and the detail view should stay aligned.

How to Read This Snapshot

Total stars are useful as a discovery signal, but they do not tell you whether a team maintains every repository equally. Pair this page with release cadence, maintainer activity, and the flagship concentration shown above before making adoption decisions.
