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to any coding prompt and it fetches current docs for the library you're working with, eliminating hallucinated APIs and outdated code examples.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.; agentic-cursorrules: This tool helps AI agents navigate large codebases by partitioning them into domain-specific contexts. It generates isolated markdown files that define explicit file-tree boundaries, preventing agents from interfering with unrelated modules and improving workflow focus.
