How to Set Up and Use Mantic
Mantic is a structural code search engine designed for AI agents that enables intelligent retrieval of relevant code context from large codebases. By connecting Mantic to Claude or Cursor, you gain the ability to search and understand code structure at scale, making it easier to provide agents with the precise context needed for code comprehension and modification tasks.
Prerequisites
- Node.js 18+ installed on your system
- An MCP client (Claude Desktop, Cursor, or VS Code with MCP support)
- Access to your codebase for indexing
Install Mantic via npx
Run the Mantic server using npx, which will start the structural code search engine on your system.
npx mantic-shAdd Mantic to your MCP client configuration
Update your client config file to include the Mantic server. Add a new entry under mcpServers with the Mantic command.
{
"mcpServers": {
"mantic": {
"command": "npx",
"args": ["mantic-sh"]
}
}
}Index your codebase
Point Mantic to your codebase directory so it can build an index for structural searches.
# Configure Mantic to index your project
# See repository README for exact indexing commandRestart your MCP client
Restart Claude Desktop, Cursor, or your MCP client to load the Mantic server connection.
Verify Mantic is connected
Test that Mantic is working by asking your AI agent to search for code patterns in your indexed codebase.

Example prompts for using Mantic with your AI agent
1. "Search for all function definitions that use async/await patterns in my codebase"
2. "Find all imports of the React library and show me how they're being used"
3. "Locate all error handling blocks and suggest improvements"Troubleshooting Mantic
Mantic server fails to start with 'command not found'
Ensure Node.js 18+ is installed and npx is in your PATH. Try running 'npx mantic-sh' directly in terminal to verify installation.
AI agent cannot find code patterns in search results
Verify that your codebase has been properly indexed. Consult the Mantic repository README for indexing setup and configuration options.
