Context7 vs sdl-mcp
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to any coding prompt and it fetches current docs for the library you're working with, eliminating hallucinated APIs and outdated code examples.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.; sdl-mcp: SDL-MCP is a Model Context Protocol (MCP) server that transforms codebases into queryable, versioned knowledge systems for AI agents. It indexes symbols and dependencies into a SQLite-backed ledger, enabling efficient, precise context retrieval, delta analysis, and policy-gated code access.
