About Ctx Sys
Ctx Sys is an MCP server in the RAG category: local hybrid RAG over a code knowledge graph. Indexes your codebase with tree-sitter + embeddings + a relationship graph and serves precise context to any AI assistant over MCP — fusing keyword (FTS5), vector, and graph search with reciprocal rank fusion. Local-first via Ollama; works with Claude Code, Cursor, and any MCP client.
