What is code-graph-context CLAUDE.md?

An MCP server that turns a TypeScript codebase into a searchable graph of files, code elements, and their relationships. MCP is a standard way for tools to provide context to an AI assistant.

Use it to search a TypeScript project, follow connections between code elements, inspect the effects of changes, and provide structured code context to an AI assistant.

It helps an AI assistant understand how code is connected instead of searching files as unrelated text. The graph can support semantic search, relationship tracing, and impact analysis.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked

Security

Grade A, and why

code-graph-context CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Agent Guide — Code Graph Context

Guidance for AI coding agents (Claude Code, Cursor, Codex, Aider, etc.) working in this repository.

Project Overview

Code Graph Context is an MCP (Model Context Protocol) server that builds code graphs to provide rich context to LLMs. It parses TypeScript codebases using AST analysis (ts-morph), stores the graph in Neo4j with vector embeddings, and provides semantic search and graph traversal tools.

Build & Development Commands

npm run build          # Compile TypeScript to dist/
npm run dev            # Watch mode compilation
npm run mcp            # Run MCP server: node dist/mcp/mcp.server.js
npm run lint           # ESLint with auto-fix
npm run format         # Prettier formatting

Architecture

Data Flow

TypeScript Project → AST Parser (ts-morph) → Graph Nodes/Edges → Neo4j + Vector Embeddings → MCP Tools

Key Directories

src/mcp/ - MCP server entry point and tools
- mcp.server.ts - Server initialization
- tools/ - 7 MCP tools (search_codebase, traverse_from_node, impact_analysis, etc.)
- handlers/ - Business logic for graph generation and traversal
src/core/ - Core business logic
- parsers/typescript-parser.ts - Main AST parser (~1000 lines)
- config/schema.ts - Core graph schema definitions
- config/nestjs-framework-schema.ts - NestJS semantic patterns
- embeddings/ - OpenAI embeddings and NL-to-Cypher services
src/storage/neo4j/ - Neo4j driver and queries

Dual-Schema System

The parser uses two schema layers:

Core Schema (AST-level): ClassDeclaration, MethodDeclaration, PropertyDeclaration, ImportDeclaration, etc.
Framework Schema (Semantic): Controller, Service, Module, Guard, Repository, etc. (NestJS patterns)

Nodes have both coreType (AST) and semanticType (framework interpretation).

Projects and Memory

One Neo4j holds many projects. Every tool takes projectId: an id (proj_<12-hex-chars>), a name, or a path. A path inside a registered project resolves to that project, and a git worktree to its main repository. A project has one of three kinds:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
