Overview

Research summary

The official Model Context Protocol SDK catalogue is a reference for choosing a maintained implementation in a developer's preferred language. Linked libraries support building servers that expose tools, resources, and prompts, and clients that consume those capabilities over supported transports. The catalogue describes SDK tiers based on protocol coverage and maintenance expectations.

The directory covers SDK implementations in multiple languages and is not itself an SDK package. Releases, implementation details, and licenses belong to the individual SDK repositories, so there is no aggregate package version or repository activity snapshot.
