Beyond tools, MCP agents can expose resources (read-only data) and prompt templates (reusable message patterns). These follow the standard MCP specification.

​
Resources

Resources represent data that MCP clients can read but not modify.

​
resources/list

Discover available resources: 
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "resources/list"
}
Response: 
{
  "jsonrpc": "2.0",
  "id": 1,
  "result": {
    "resources": [
      {
        "uri": "beeos://agent/config",
        "name": "Agent Configuration",
        "description": "Current agent configuration and capabilities",
        "mimeType": "application/json"
      },
      {
        "uri": "beeos://agent/skills",
        "name": "Skill Registry",
        "description": "List of all registered skills with metadata",
        "mimeType": "application/json"
      }
    ]
  }
}

​
resources/read

Read a specific resource by URI: 
{
  "jsonrpc": "2.0",
  "id": 2,
  "method": "resources/read",
  "params": {
    "uri": "beeos://agent/config"
  }
}
Response: 
{
  "jsonrpc": "2.0",
  "id": 2,
  "result": {
    "contents": [
      {
        "uri": "beeos://agent/config",
        "mimeType": "application/json",
        "text": "{\"name\":\"Research Assistant\",\"model\":\"gpt-4o\",\"skills\":[\"web_search\",\"summarize\"]}"
      }
    ]
  }
}

​
Prompt templates

Prompt templates are reusable message patterns that MCP clients can present to users.

​
prompts/list

{
  "jsonrpc": "2.0",
  "id": 3,
  "method": "prompts/list"
}
Response: 
{
  "jsonrpc": "2.0",
  "id": 3,
  "result": {
    "prompts": [
      {
        "name": "research",
        "description": "Research a topic and provide a summary",
        "arguments": [
          {
            "name": "topic",
            "description": "The topic to research",
            "required": true
          },
          {
            "name": "depth",
            "description": "Research depth: brief, standard, or deep",
            "required": false
          }
        ]
      }
    ]
  }
}

​
prompts/get

Render a prompt template with arguments: 
{
  "jsonrpc": "2.0",
  "id": 4,
  "method": "prompts/get",
  "params": {
    "name": "research",
    "arguments": {
      "topic": "quantum computing",
      "depth": "deep"
    }
  }
}
Response: 
{
  "jsonrpc": "2.0",
  "id": 4,
  "result": {
    "messages": [
      {
        "role": "user",
        "content": {
          "type": "text",
          "text": "Research quantum computing in depth. Provide a comprehensive summary covering recent advances, key players, and practical applications."
        }
      }
    ]
  }
}

​
Example: full resource flow

# List resources
curl -s -X POST "https://mcp.beeos.ai/${AGENT_ID}/mcp" \
  -H "X-Agent-API-Key: bak_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"resources/list"}' | jq '.result.resources'

# Read a resource
curl -s -X POST "https://mcp.beeos.ai/${AGENT_ID}/mcp" \
  -H "X-Agent-API-Key: bak_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":2,"method":"resources/read","params":{"uri":"beeos://agent/config"}}' | jq

# List prompts
curl -s -X POST "https://mcp.beeos.ai/${AGENT_ID}/mcp" \
  -H "X-Agent-API-Key: bak_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":3,"method":"prompts/list"}' | jq '.result.prompts'

​
Availability

Not all agents expose resources or prompts. The response may contain an empty array if the agent has not registered any: 
{
  "jsonrpc": "2.0",
  "id": 1,
  "result": {
    "resources": []
  }
}
This is normal behavior and not an error.
