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to any coding prompt and it fetches current docs for the library you're working with, eliminating hallucinated APIs and outdated code examples.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.; mcp-language-server: The MCP Language Server exposes language server capabilities like definition, references, and diagnostics to Large Language Models. It helps MCP-enabled clients navigate codebases more easily by providing semantic tools for code understanding and manipulation.
