An open-source Model Context Protocol (MCP) server that adds a persistent code intelligence layer to AI coding assistants — Claude Code, VS Code Copilot, Cursor, and Claude Desktop. Unlike static RAG or batch-oriented GraphRAG, lxDIG MCP is a live, incrementally-updated intelligence graph that turns any repository into a queryable knowledge graph — so agents can answer architectural questions, track decisions across sessions, coordinate safely in multi-agent workflows, and run only the tests that actually changed — without re-reading the entire codebase on every turn.
It is purpose-built for the agentic coding loop: the cycle of understand → plan → implement → verify → remember that AI agents (Claude, Copilot, Cursor) repeat continuously.
The core problem it solves: most AI coding assistants are stateless and architecturally blind. They re-read unchanged files on every session, miss cross-file relationships, forget past decisions, and collide when multiple agents work in parallel. lxDIG MCP is the memory and structure layer that fixes all four.
Most code intelligence tools solve one of these problems. lxDIG solves all of them together:

init_project_setup — sets workspace, rebuilds graph, generates Copilot instructionssetup_copilot_instructions — generates .github/copilot-instructions.md from your repo's topologylxDIG runs as an MCP server over stdio or HTTP and coordinates three data planes behind a single tool interface:

When you call graph_query in natural language mode, retrieval runs as hybrid fusion:
The result: structurally accurate, semantically relevant answers — not just the closest embedding match.
lxDIG Visual is the open-source browser-based visualization layer for lxDIG MCP. It renders your code dependency graph as an interactive, navigable canvas — turning abstract code relationships into a tangible spatial representation you can explore.
Key features:
Setup (shares the same Memgraph instance as lxDIG MCP — no extra database needed):
git clone https://github.com/lexCoder2/lxDIG-visual.git
cd lxDIG-visual
npm install && cp .env.example .env
npm run dev:all
# Open http://localhost:5173
After indexing with graph_rebuild, changes appear in the visual explorer immediately — no manual refresh required.
Recommended setup: Memgraph + Qdrant in Docker, MCP server on your host via stdio. Your editor spawns and owns the process — no HTTP ports, no session headers.
git clone https://github.com/lexCoder2/lxDIG-MCP.git
cd lxDIG-MCP
npm install && npm run build
docker compose up -d memgraph qdrant
docker compose ps # wait for "healthy" (~30 s)

This single call sets the workspace context, rebuilds the code graph, and generates .github/copilot-instructions.md for your project. Your agent is ready to query.
Total setup time: ~5 minutes. See QUICK_START.md for the full guide including Docker, Claude Desktop, and HTTP transport.

src/tools/; include testssrc/parsers/lxDIG MCP is built and maintained in personal time — researching graph retrieval techniques, designing the tool surface, writing tests, and keeping everything working across MCP protocol updates. If it saves you time or makes your AI-assisted workflows meaningfully better, consider supporting the work:
Q: Does lxDIG require a cloud service or API key? No. lxDIG runs entirely on your machine. Memgraph and Qdrant run in Docker containers you control. No data leaves your environment.
Q: Does it work with Cursor? Yes. Any MCP-compatible client works. Add the stdio config to Cursor's MCP settings the same way as VS Code.
Q: How large a codebase can it handle?
The graph plane (Memgraph) scales to millions of nodes. For very large monorepos, use sourceDir to scope indexing to the relevant subdirectory. Incremental rebuilds keep the graph fresh without re-indexing everything.
Q: Do I need to run Qdrant?
Qdrant is optional but recommended for large codebases. Without it, semantic_search and find_similar_code are unavailable; all other tools continue to work via graph-only or BM25 retrieval.
Q: Can multiple developers on a team share one lxDIG instance? Yes, via HTTP transport. One running instance handles multiple independent sessions. Team-level shared memory is on the lxDIG Cloud roadmap.
Q: Is this production-ready? The core tools are stable and tested (402 tests, all green). Treat it as beta — APIs may change before a 1.0 release. Pin your version and watch the changelog.
Q: Is lxDIG MCP the same as GraphRAG? No. GraphRAG is a batch retrieval technique applied to documents. lxDIG MCP is a live, incrementally-updated code graph with persistent agent memory, multi-agent coordination, and impact-scoped test selection — not just a retrieval improvement.
Q: How do I add persistent memory to Claude Code?
Install lxDIG MCP, add the stdio config to .vscode/mcp.json, and call init_project_setup once per repository. From that point, Claude Code can call episode_add / episode_recall and decision_query to read and write memory that persists across sessions.
Q: Can I visualize the code graph?
Yes. lxDIG Visual is the companion browser-based graph explorer. It shares the same Memgraph instance — run npm run dev:all in the lxDIG-visual repo and open http://localhost:5173.
