I Burned a Month's AI Budget in a Week — So I Built a Code Graph
Short summary
AI API costs spike when tools dump entire code files as context. Nexus-Graph solves this by parsing your codebase into a directed symbol graph and serving token-budgeted context via MCP—the protocol Claude Code and Cursor speak natively. The result: 70% fewer tokens per query, 5–10x smaller context, and sub-100ms response times on large codebases.
- •Inefficient file-based code retrieval inflates AI API costs (the "Confusion Tax")
- •Graph-based symbol traversal provides surgical context vs. whole-file dumps
- •Achieves 70% token reduction with sub-100ms queries; MIT licensed and npm-installable
Generated with AI, which can make mistakes.
Is this a good recommendation for you?
