Context-Engine vs sdl-mcp

Context-Engine: Context-Engine is an open-core, self-improving code search tool that integrates with AI coding assistants. It allows developers to search their codebase, get answers with citations, and enhances AI agents' ability to explore code using its MCP tools.; 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.
