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to any coding prompt and it fetches current docs for the library you're working with, eliminating hallucinated APIs and outdated code examples.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.; codex-mcp-tool: This MCP server integrates Claude/Cursor with the Codex CLI, enhancing AI-powered code interactions. It enables advanced features like file analysis, multi-turn conversations, sandboxed code execution, and structured change management.
