SDKs

> Software Development Kits for MCP server development.

How are SDKs ordered?

SDKs are ordered by their popularity as determined by GitHub stars.

If an SDK is part of a monorepo, it should have a name in the form of github-owner/github-repo#project-name.

If an SDK is part of a monorepo, its popularity is counted as 0 stars.
