What is CoreStory

From Raw Code to Code Intelligence.

AI coding agents are only as good as the context they receive. When you throw raw source code at a coding agent, it re-ingests the same modules, schemas, and functions every single session — burning tokens on context it already processed.

CoreStory transforms your entire codebase into a persistent Code Intelligence Model — a complete specification of how your code works. Instead of raw code files, AI coding agents receive structured intelligence.

The result: AI agents produce correct code on the first attempt — no guessing at dependencies, no hallucinating business rules, no repeated correction rounds, no wasted tokens.

How CoreStory Works

  1. Ingest your codebase once
    Static analysis, call graph extraction, and data flow tracing across your entire codebase.

  2. Get a full Code Intelligence Model
    A persistent Code Intelligence Model captures architecture, business rules, behavior contracts — not raw implementation code.

  3. Deliver context via MCP
    Any MCP-compatible agent queries the CIM and gets exactly what it needs. Works with Claude Code, Cursor, Copilot, Devin, IBM Bob...

  4. Generate code right, first try
    Fewer tokens consumed, fewer correction rounds, fewer hallucinations. Right output on the first attempt.

Proven Results

Beyond cost savings. Real quality gains.

Token savings are the most measurable benefit. The compounding effect on code quality and team productivity can be even more significant.

  • 73% Fewer Input Tokens
    In a real enterprise evaluation, Claude Code paired with CoreStory MCP consumed 73% fewer input tokens for a complex feature implementation task.

  • 51% Accuracy Improvement
    Microsoft + GitHub co-research found a 51% accuracy improvement when AI agents operate from CoreStory specifications rather than raw source code.

  • 44% More Tasks Completed
    Teams using CoreStory get 44% more tasks completed - measured against the hardest tasks in SWE-benchmark, the industry standard for agentic code generation performance.

Platform

Works with the tools your team already uses.

CoreStory integrates via MCP — no rip-and-replace, no new workflows. Your agents get smarter; your team keeps working the same way.

  1. MCP Integration
    CoreStory exposes your CIM as an MCP server. Claude Code, Cursor, GitHub Copilot, Devin, and any MCP-compatible agent can query it immediately.

  2. Multi-Language Support
    Java, C#, Python, COBOL, PowerBuilder, SystemVerilog, and many more. CoreStory handles the polyglot enterprise codebase as-is.

  3. Always Current
    CIMs are regenerated from source, so they always reflect the actual codebase — not the last time someone updated the wiki.
