Clewso

The Open Source Context Server for AI Agents.

Clewso indexes your codebase and gives AI agents structured, navigable context by combining vector search (Qdrant) with graph traversal (Neo4j). It solves the "Lost in the Middle" problem so your agents actually understand your code.

Features

• Hybrid search — semantic vector search + code graph traversal in one query
• MCP tools — drop-in tools for Claude Code, Cursor, Copilot, and more
• Smart review — context-aware PR review powered by impact graph analysis
• Local-first — runs on your machine, indexes your repo, 100% privacy
• Three packages — install what you need:
  • clewso — CLI with review, index, and editor setup commands
  • clewso-ingestion — repo indexing pipeline
  • clewso-core — shared types and embedding client

Quick start

pip install clewso
docker compose up -d   # Neo4j + Qdrant
clewso index ./my-repo
clewso setup-editor    # auto-detect and configure your editor

See the installation guide for full setup instructions.
