Reflex
로컬 우선, 전체 텍스트 코드 검색 MCP 서버로 AI 코딩 에이전트용입니다. 트라이그램 기반 인덱싱으로 코드베이스를 인덱싱하여 100ms 미만의 쿼리를 제공합니다. 에이전트는 10,000개 이상의 파일을 검색하고, 언어나 심볼 종류별로 필터링하며, 구조화된 JSON 결과를 얻을 수 있습니다. 모두 오프라인에서 작동하며 API 키가 필요하지 않습니다.

Why Reflex
Fast at Scale
Indexes a 27,448-file Kubernetes checkout in 7.7s on 16 cores. Median queries on a 30 MB corpus: ~3ms for a common word, ~12ms for a regex.
Complete Coverage
Finds every occurrence — not just definitions — across the same files ripgrep searches. Whole-identifier matching by default, plus substring and case-insensitive search.
AI-Native
MCP server with 17 tools, JSON output for agent pipelines, built-in AI query assistant. In A/B tests, same task success at ~31% lower cost per task.
15 Languages + Text
Rust, TypeScript, Python, Go, Java, C/C++, and more, parsed with Tree-sitter for precise symbols. Every other non-binary file is indexed for full-text search.
Dependency Analysis
Import tracking, reverse lookups, circular detection, hotspot analysis across your entire codebase.
Deterministic
Fully local, fully offline. Same query, same results, and every response says whether the index is fresh. Your code stays on your machine.
