⚙️ Configuration

Creating New Tools

The project includes a script to help create new MCP tools:

npm run scripts/create-tool.ts <tool-name>

This will:

1. Create a new tool directory under src/tools/<tool-name>
2. Generate the basic tool structure including:
   • index.ts (main implementation)
   • schema.ts (JSON schema for tool parameters)
   • test.ts (test file)
3. Update the tools index file to export the new tool

Example:

npm run scripts/create-tool.ts weather
