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.
