SCIP indexing (optional)

When SCIP_INDEXER=true in your CGC config (~/.codegraphcontext/.env), some languages use external SCIP indexers for more accurate calls and inheritance than Tree-sitter heuristics alone.

C and C++ use scip-clang, which requires a compile_commands.json file (a JSON compilation database): one entry per translation unit with the real compiler command (include paths, -D defines, -std, etc.). Without it, scip-clang cannot run; CGC logs a warning and falls back to Tree-sitter for that repo. Typical ways to produce the file: CMake with -DCMAKE_EXPORT_COMPILE_COMMANDS=ON, or wrap your real build with Bear (e.g. bear -- make). CGC also looks under build/ and cmake-build-*/ for that filename.

C# uses scip-dotnet (Roslyn); you need a normal .csproj / .sln and a successful restore—no compile_commands.json.

SCIP is independent of which graph database you use (Kuzu, Neo4j, etc.); the same flag applies to all backends.

🤖 For MCP Server Mode

Configure your AI assistant to use CodeGraphContext:

1. Setup: Run the MCP setup wizard to configure your IDE/AI assistant:

   codegraphcontext mcp setup

   The wizard can automatically detect and configure:

   • VS Code
   • Cursor
   • Windsurf
   • Zed
   • Claude
   • Gemini CLI
   • ChatGPT Codex
   • Cline
   • RooCode
   • Amazon Q Developer
   • Kiro
   • Goose
   • OpenCode

   Upon successful configuration, codegraphcontext mcp setup will generate and place the necessary configuration files:

   • It creates an mcp.json file in your current directory for reference.
   • It stores your database credentials securely in ~/.codegraphcontext/.env.
   • It updates the settings file of your chosen IDE/CLI (e.g., .claude.json or VS Code’s settings.json).

2. Start: Launch the MCP server:

   codegraphcontext mcp start

3. Use: Now interact with your codebase through your AI assistant using natural language! See examples below.

---

Ignoring Files (.cgcignore)

You can tell CodeGraphContext to ignore specific files and directories by creating a .cgcignore file in the root of your project. This file uses the same syntax as .gitignore.

Example .cgcignore file:

# Ignore build artifacts
/build/
/dist/

# Ignore dependencies
/node_modules/
/vendor/

# Ignore logs
*.log

---

MCP Client Configuration

The codegraphcontext mcp setup command attempts to automatically configure your IDE/CLI. If you choose not to use the automatic setup, or if your tool is not supported, you can configure it manually.

Add the following server configuration to your client’s settings file (e.g., VS Code’s settings.json or .claude.json):

{
  "mcpServers": {
    "CodeGraphContext": {
      "command": "codegraphcontext",
      "args": [
        "mcp",
        "start"
      ],
      "env": {
        "NEO4J_URI": "YOUR_NEO4J_URI",
        "NEO4J_USERNAME": "YOUR_NEO4J_USERNAME",
        "NEO4J_PASSWORD": "YOUR_NEO4J_PASSWORD"
      },
      "disabled": false,
      "alwaysAllow": []
    }
  }
}

OpenCode Configuration

For instructions on installing and configuring MCP servers with OpenCode, see the OpenCode MCP Guide.

If installed via pipx

If you installed CodeGraphContext using pipx, use the following configuration instead:

{
  "mcpServers": {
    "CodeGraphContext": {
      "command": "pipx",
      "args": [
        "run",
        "codegraphcontext",
        "mcp",
        "start"
      ],
      "env": {
        "NEO4J_URI": "YOUR_NEO4J_URI",
        "NEO4J_USERNAME": "YOUR_NEO4J_USERNAME",
        "NEO4J_PASSWORD": "YOUR_NEO4J_PASSWORD"
      },
      "disabled": false,
      "alwaysAllow": []
    }
  }
}

Natural Language Interaction Examples

Once the server is running, you can interact with it through your AI assistant using plain English. Here are some examples of what you can say:

Indexing and Watching Files

• To index a new project:

  • “Please index the code in the /path/to/my-project directory.” OR
  • “Add the project at ~/dev/my-other-project to the code graph.”

• To start watching a directory for live changes:

  • “Watch the /path/to/my-active-project directory for changes.” OR
  • “Keep the code graph updated for the project I’m working on at ~/dev/main-app.”

  When you ask to watch a directory, the system performs two actions at once:

  1. It kicks off a full scan to index all the code in that directory. This process runs in the background, and you’ll receive a job_id to track its progress.
  2. It begins watching the directory for any file changes to keep the graph updated in real-time.

  This means you can start by simply telling the system to watch a directory, and it will handle both the initial indexing and the continuous updates automatically.

Querying and Understanding Code

• Finding where code is defined:

  • “Where is the process_payment function?”
  • “Find the User class for me.”
  • “Show me any code related to ‘database connection’.”

• Analyzing relationships and impact:

  • “What other functions call the get_user_by_id function?”
  • “If I change the calculate_tax function, what other parts of the code will be affected?”
  • “Show me the inheritance hierarchy for the BaseController class.”
  • “What methods does the Order class have?”

• Exploring dependencies:

  • “Which files import the requests library?”
  • “Find all implementations of the render method.”

• Advanced Call Chain and Dependency Tracking (Spanning Hundreds of Files): The CodeGraphContext excels at tracing complex execution flows and dependencies across vast codebases. Leveraging the power of graph databases, it can identify direct and indirect callers and callees, even when a function is called through multiple layers of abstraction or across numerous files. This is invaluable for:

  • Impact Analysis: Understand the full ripple effect of a change to a core function.

  • Debugging: Trace the path of execution from an entry point to a specific bug.

  • Code Comprehension: Grasp how different parts of a large system interact.

  • “Show me the full call chain from the main function to process_data.”

  • “Find all functions that directly or indirectly call validate_input.”

  • “What are all the functions that initialize_system eventually calls?”

  • “Trace the dependencies of the DatabaseManager module.”

• Code Quality and Maintenance:

  • “Is there any dead or unused code in this project?”
  • “Calculate the cyclomatic complexity of the process_data function in src/utils.py.”
  • “Find the 5 most complex functions in the codebase.”

• Repository Management:

  • “List all currently indexed repositories.”
  • “Delete the indexed repository at /path/to/old-project.”
