Feature & Specification Comparison

Specification	Rag Rat cq27-dev Knowledge & Memory	Ctxfile ctxfile Knowledge & Memory
Summary	Local repo-intelligence index and MCP server for coding agents — "what a repository knows about itself." Hybrid BM25 + vector semantic search, a tree-sitter code graph (callers/callees/imports across Rust, TS/TSX, Kotlin, C/C++, Python) with an optional compiler-grade SCIP oracle, queryable git/GitHub history, and typed, source-anchored repo memories (Invariant, Decision, Risk, …) that persist across sessions. Every result carries provenance — confidence labels and coverage warnings. Keeps source read-only; a background watcher keeps queries fresh. PreToolUse hooks augment grep and flag near-duplicate code as you write it. cargo install rag-rat	Local-first MCP server that snapshots your project's working state — files, git, plan, and decisions — into one structured context object and hands it to any MCP client in a single call. Save a session in one agent, continue it in another. Zero network calls by default; read-only over your project. Works with Claude Code, Cursor, and any MCP client. npx -y ctxfile
