Does the ADK LLM Agent use MCP prompt and resources?

[shivsant]

The MCP servers can contains tools (I am using Stdio MCP server) - I can use them in the adk framework,

Can I similarly use prompt and resource decorators? Any examples?

Response from ADK Answering Agent (experimental, answer may be inaccurate)

TLDR: The @prompt and @resource decorators are part of the MCP server implementation, not something you use directly in your ADK agent code. To use tools, prompts, and resources from an MCP server, you should use the MCPToolset in your ADK agent.

Hello! That's a great question. The way ADK interacts with MCP servers can be a bit nuanced. Here's a breakdown:

The @prompt and @resource decorators you're asking about are typically used on the MCP server side to define and expose resources and prompts to clients. You wouldn't use these decorators directly within your ADK agent's code.

In the ADK framework, you act as a client to the MCP server. To connect your LlmAgent to an MCP server and use its capabilities (including tools, and by extension, the prompts and resources the server provides), you should use the MCPToolset.

Here's an example of how you would connect to an MCP server from your ADK agent:

from adk.llm import LlmAgent
from adk.mcp import MCPToolset

# The address of your MCP server
mcp_server_address = '0.0.0.0:12345'

# Create an MCPToolset to connect to the server
mcp_tools = MCPToolset(mcp_server_address=mcp_server_address)

# Create your agent and pass the toolset
my_agent = LlmAgent(
    tools=[mcp_tools]
)

# Now your agent can use the tools from the MCP server
my_agent.chat("Use the tools from the MCP server to do something.")

So, while you can't use the decorators directly, you can certainly leverage the functionality they provide on the server by connecting your agent to it as shown above.

For more details on how to use MCPToolset and integrate with MCP servers, you can refer to the official documentation. [1]
