### Example MCP Server Configuration (JSON)

Source: https://kiro.dev/docs/autonomous-agent/sandbox/mcp

This JSON object demonstrates how to configure an AWS knowledge MCP server. It specifies the command to run and its arguments, allowing the agent to access external data sources during task execution. The configuration is loaded when the sandbox starts.

```json
{
  "mcpServers": {
    "aws-knowledge-mcp-server": {
      "command": "uvx",
      "args": [
        "fastmcp",
        "run",
        "https://knowledge-mcp.global.api.aws"
      ],
      "env": {}
    }
  }
}
```

### Dockerfile Configuration for Node.js Application

Source: https://kiro.dev/docs/autonomous-agent/sandbox/devfile

This Dockerfile sets up a Node.js application environment. It uses the `node:18` image, installs dependencies using `npm`, copies application code, sets the environment to production, exposes port 3000, and defines the start command. Requires `npm` and Node.js.

```dockerfile
FROM node:18

WORKDIR /app

# Install dependencies
COPY package*.json ./
RUN npm install

# Copy application code
COPY . .

# Set environment variables
ENV NODE_ENV=production

# Expose port
EXPOSE 3000

# Start command
CMD ["npm", "start"]

```

### MCP Configuration with Environment Variables and Secrets (JSON)

Source: https://kiro.dev/docs/autonomous-agent/sandbox/mcp

This JSON configuration illustrates how to securely pass credentials and configuration values to MCP servers using environment variables and secrets. The `${key_name}` syntax is used to reference these values, which are resolved when the sandbox starts.

```json
{
  "mcpServers": {
    "server-name": {
      "command": "executable",
      "args": ["arg1", "arg2"],
      "env": {
        "ENV_VAR_KEY": "${my_env_var_key}",
        "SECRET_KEY": "${my_secret_key}"
      }
    }
  }
}
```

### DevFile Configuration for Node.js Project

Source: https://kiro.dev/docs/autonomous-agent/sandbox/devfile

This DevFile configures a Node.js project environment. It specifies the container image, memory limits, source mounting, and commands for installing dependencies, running the application, and testing. It requires `npm` to be available in the `node:18` image.

```yaml
schemaVersion: 2.2.0
metadata:
  name: nodejs-app
  version: 1.0.0

components:
  - name: runtime
    container:
      image: node:18
      memoryLimit: 1024Mi
      mountSources: true

commands:
  - id: install
    exec:
      component: runtime
      commandLine: npm install
      workingDir: ${PROJECT_SOURCE}
  
  - id: run
    exec:
      component: runtime
      commandLine: npm start
      workingDir: ${PROJECT_SOURCE}
  
  - id: test
    exec:
      component: runtime
      commandLine: npm test
      workingDir: ${PROJECT_SOURCE}

```
