Context7: Context7 is an MCP server that injects up-to-date, version-specific library documentation directly into LLM prompts. Add "use context7" to any coding prompt and it fetches current docs for the library you're working with, eliminating hallucinated APIs and outdated code examples. Works with Claude Desktop, Cursor, Windsurf, and any MCP-compatible editor.; golf: Golf is a Python framework designed to streamline the creation of MCP server applications by defining capabilities as Python files. It automatically discovers, parses, and compiles these components into a runnable MCP server, minimizing boilerplate and accelerating development.
