Context7 vs pg-aiguide
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to any coding prompt and it fetches current docs for the library you're working with, eliminating hallucinated APIs and outdated code examples.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.; pg-aiguide: pg-aiguide enhances AI coding tools by providing deep, versioned PostgreSQL knowledge and proven best practices, helping them generate dramatically better database code. It prevents AI from producing outdated, incomplete, or non-optimal Postgres schemas by integrating semantic search of manuals and AI-optimized "skills."
