🛠️ Advanced Configuration & Security

Custom Tool Development

Develop new MCP tools by leveraging the built-in template script:

bun run scripts/create-tool.ts weather

This command creates a new directory for the tool, complete with basic implementation files and updates to the main tool index.

Environment Variable Management

Environment variables can be configured via the env section in your MCP client configuration. Below is an example of setting up environment variables:

{
  "mcpServers": {
    "weatherServer": {
      "command": "node",
      "args": ["/path/to/your/project/dist/main.js", "some_argument"],
      "env": {
        "API_KEY": process.env.API_KEY,
        "SECRET_KEY": process.env.SECRET_KEY
      }
    }
  }
}
