consul-adk

This is an AI Agent Development Kit(ADK) built on top of Google ADK to implement Agentic Service Mesh. Using this and Consul CE/ENT, you can discover and scale the Agents and MCP servers and create a desired agent graph using Service intentions. The ADK help to create the desired client's for the Agents and MCP servers as soon as the intentions are defined in Consul.

Installation

pip install consul-adk

Usage Example

Below is a simple example to get you started:

A simple agent with hardcoded instructions

# 🧠 Gemini-based AI agent provided by Google's ADK
from google.adk.agents.llm_agent import LlmAgent
from google.adk.tools import FunctionTool
from utilities.consul_agent import ConsulEnabledAIAgent

class WeatherAgent(ConsulEnabledAIAgent):

    def build_agent(self) -> LlmAgent:
        """
        ⚙️ Creates and configures a Gemini agent with weather capabilities.

        Returns:
            LlmAgent: A configured agent object from Google's ADK
        """
        # Manually adding the WeatherTool to the agent's tools
        tools = [
            FunctionTool(WeatherTool(name="WeatherTool", description="Gets the realtime weather for one or more locations").get_weather)
        ]

        # Automatically add MCP tools as they are registered in Consul and Intentions are defined
        for tool_set in self._remote_mcp_tools.values():
            tools.append(tool_set)

        return LlmAgent(
            model="gemini-1.5-flash-latest",  # Gemini model version

When asked about weather, extract the 'locations' parameter as a list (even for a single location), then use the 'WeatherTool' to provide weather information.

        )
from google.adk.tools import BaseTool

An orchestrator agent which adapts its instructions by reading the child-agent card.

        )

        return ai_agent

Features

• Auto discover AI agents and creates their client connections in this agent as soon as Consul intentions are defined
• Auto-configure agents and MCP servers
• Send and manage tasks between agents
