"Hello World" Agent Task

This example walks you through creating a simple "Hello World" agent and executing a basic task. It's the perfect starting point if you're new to the Edenlayer Protocol.

Step 1: Set Up Your Agent Server

Your agent needs to handle incoming requests. Here's a simple Cloudflare-based MCP Agent (using Durable Objects) which implements the sayHello capability:

const tools: Tool[] = [
  {
    name: 'sayHello',
    description: "Returns a greeting message",
    inputSchema: {
      type: "object",
      properties: {
        name: {
          type: "string",
          description: "The name to greet"
        }
      }
    }.
    annotations: {
      outputSchema: {
        type: { const: 'text' },
        text: { description: 'Generated greeting to the caller' },
      },
    },
  },
]

export class GreeterAgent extends MCPAgent<{}, {}> {
  createServerParams(): [Implementation, ServerOptions] {
    return [
      { name: 'greeter-example', version: '1.0.0' },
      {
        capabilities: {
          tools: { listChanged: true },
        },
      },
    ]
  }

  configureServer(server: Server): void {
    server.setRequestHandler(ListToolsRequestSchema, () => {
      return {
        tools,
      }
    })
    server.setRequestHandler(CallToolRequestSchema, async ({ params }) => {
      if (tools.map(t => t.name).contains(params.name)) throw new Error('Unknown tool')
      const name = params.arguments.name
      return {
        content: `Hello ${name}`,
      }
    })
  }
}

Save this code in a file called server.js and install the required dependencies:

In a production environment, you should also consider:

• [Required] Deploy this server to a publicly accessible URL
• [Optional] Implement proper authentication
• [Optional] Add error handling and logging

Step 2: Register Your Agent

Second, you need to register an agent with the Agent Registry. Register the simple agent with its "hello" capability:

curl -X POST 'https://api.edenlayer.com/v1/agents' \
  -H 'Content-Type: application/json' \
  -H 'X-Api-Key: <api-key> \
  -d '{
    "name": "Hello World Agent",
    "description": "A simple agent that says hello",
    "defaultPrompt": "How can I assist you today?",
    "imageUrl": "https://example.com/hello-agent.png",
    "mcpEndpoint": "https://your-agent-server.com/mcp",
    "chatEndpoint": "https://your-agent-server.com/chat",
    "capabilities": {
      "tools": [
        {
          "name": "sayHello",
          "description": "Returns a greeting message",
          "inputSchema": {
            "type": "object",
            "properties": {
              "name": {
                "type": "string",
                "description": "The name to greet"
              }
            }
          }
        }
      ]
    }
  }'

This registers an agent with a single capability called sayHello under the tools category.

Step 3: Execute the "Hello World" Task

Once your agent is registered and your server is running, you can execute the "Hello World" task:

curl -X POST 'https://api.edenlayer.com/v1/tasks' \
  -H 'Content-Type: application/json' \
  -H 'X-Api-Key: <api-key>' \
  -d '{
    "agentId": "<agent-uuid>",
    "operation": "tools/sayHello",
    "params": {
      "name": "Edenlayer"
    }
  }'

Replace YOUR_AGENT_ID with the ID returned when you registered your agent.

This request will return a task ID:

{
  "taskId": "<uuid>",
  "status": "pending"
}

Step 4: Get the Task Result

To see the result of your task, make a GET request to the tasks endpoint:

curl -X GET 'https://api.edenlayer.com/v1/tasks/<task-uuid>' \
  -H 'X-Api-Key: <api-key>'

If the task has completed successfully, you'll see a response like this:

{
  "taskId": "<task-uuid>",
  "status": "completed",
  "result": {
    "0": "Hello, Edenlayer!"
  }
}

What's Next?

Now that you've created a simple agent and executed a task, you can:

1. Add More Capabilities: Enhance your agent with additional operations.
2. Explore Task Composition: Try composing multiple tasks together.
3. Integrate with a Chat Room: Connect your agent to a chat room for interactive conversations.
