Learn to build a knowledge graph from enterprise source code to transform a codebase into a structured, queryable model

intermediate Published 15 May 2026
Action Steps
  1. Parse source code into Abstract Syntax Trees (ASTs) using tools like GitNexus
  2. Extract relationships between code entities from ASTs
  3. Store the graph in a database like CodeGraph
  4. Implement incremental updates to keep the graph up-to-date
  5. Deliver agent-based insights via Model Serving Platforms (MCP)

TL;DR A code knowledge graph transforms a codebase from a collection of text files into a structured, queryable model of how the system actually works. The architecture involves five phases: AST parsing, relationship extraction, graph storage, incremental updates, and agent delivery via MCP. Open-source tools like GitNexus, Potpie AI, and CodeGraph have proven the approach works for individual developers. CoreStory's Code Intelligence Model applies the same archi
