sdl-mcp vs CogniLayer

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.; CogniLayer: CogniLayer is an advanced tool that equips AI agents with persistent knowledge and deep code intelligence, preventing them from repeatedly learning your codebase. It significantly saves tokens by compressing context and providing immediate access to architectural understanding, past decisions, and bug fixes.
