How to Set Up and Use Deep Graph
The Deep Graph MCP server (mcp-code-graph) connects AI coding assistants to DeepGraph and CodeGPT code graph indexes, enabling semantic search over repository architecture, direct source code retrieval, dependency analysis, and documentation search through natural language. It exposes seven specialized tools that understand code relationships rather than just text patterns, making it possible for an AI agent to navigate large codebases, understand how components connect, and reason about the impact of proposed changes. It supports both public GitHub repositories and private graphs authenticated via CodeGPT API keys.
Prerequisites
- Node.js 18+ with npx available
- An MCP-compatible client such as Claude Code or Claude Desktop
- For public graphs: a GitHub repository name in the format owner/repository-name
- For private graphs: a CodeGPT API key (CODEGPT_API_KEY), organization ID, and graph ID from codegpt.co
Add the server for a public GitHub repository
For publicly indexed repositories, pass the owner/repository path as the argument to mcp-code-graph. No API key is needed.
claude mcp add "Deep Graph MCP" npx -- -y mcp-code-graph@latest owner/repository-nameAdd the server for a private CodeGPT graph
For private code graphs, pass your CodeGPT API key, organization ID, and graph ID as positional arguments.
claude mcp add "Deep Graph MCP" npx -- -y mcp-code-graph@latest YOUR_CODEGPT_API_KEY YOUR_ORG_ID YOUR_GRAPH_IDShare the server with a project team
Add the -s project flag to store the MCP configuration in the project's .mcp.json file so all team members share the same code graph connection.
claude mcp add -s project "Deep Graph MCP" npx -- -y mcp-code-graph@latest owner/repository-nameVerify the server is registered
List registered MCP servers and inspect the Deep Graph entry to confirm it is active and pointing at the correct repository.
claude mcp list
claude mcp get "Deep Graph MCP"Add to Claude Desktop config (alternative)
If using Claude Desktop rather than Claude Code CLI, add the server block manually to claude_desktop_config.json.

}Deep Graph Examples
Client configuration (public repository)
Connect Claude Desktop to the mcp-code-graph server for a public GitHub repository. Replace owner/repo with the actual repository path.

}
}
}Prompts to try
Use these prompts to explore code architecture and relationships once the server is connected.
- "List all available code graphs for this repository"
- "Semantically search for functions related to user authentication in this codebase"
- "Show me the direct dependencies of the DatabaseService class"
- "What would break if I changed the getUserData function in DatabaseService?"
- "Retrieve the source code for the payment processing module"
- "Give me the folder structure of the src directory"Troubleshooting Deep Graph
nodes-semantic-search returns no results for a public repository
Not all repositories have been indexed by DeepGraph. Check if the repository appears on deepgraph.com or codegpt.co. If it is not indexed, you will need to create a private graph using the CodeGPT platform.
Authentication fails for private graphs with CODEGPT_API_KEY
Ensure the API key, org ID, and graph ID are passed in the correct positional order as arguments to mcp-code-graph. Verify your API key is active in the CodeGPT dashboard at codegpt.co.
npx -y mcp-code-graph@latest is very slow to start
npx downloads the package on first run. Install it globally with 'npm install -g mcp-code-graph' for faster startup, then replace 'npx -y mcp-code-graph@latest' with 'mcp-code-graph' in your config.
