🟢 Google Skills Lab - Use Model Context Protocol (MCP) Tools with ADK Agents

• Lab - https://www.skills.google/paths/3273/course_templates/1275/labs/606599

👉 Task 1. Install the ADK and set up your environment

git clone https://github.com/nov05/gcp-adk-mcp-tools.git
cd gcp-adk-mcp-tools
export PATH=$PATH:"/home/${USER}/.local/bin"
python3 -m pip install google-adk -r adk_mcp_tools/requirements.txt

👉 Task 2. Use the Google Maps MCP server with ADK agents (ADK as an MCP client) in the ADK Dev UI

Get an API key and enable the APIs

• Go to the Google Cloud console browser tab (not your Cloud Shell Editor).
  Search for APIs in the search bar at the top of the page. Select it from the results.
  Go to APIs & Services → Library, try enabling: Places API, and click + Create Credential.
  For Name, type GOOGLE_MAPS_API_KEY. Click Create.
  The API key created dialog displays your newly created API key. Be sure to copy and save this key locally for use later in the lab.

export GOOGLE_MAPS_API_KEY=AIzaSyAOGDeMSVXFEYml9PCpWM4hpTTQvWveoo4  # ⚠️ Your own key

cd ~/gcp-adk-mcp-tools/adk_mcp_tools
cat << EOF > google_maps_mcp_agent/.env
GOOGLE_GENAI_USE_VERTEXAI=TRUE
# GOOGLE_CLOUD_PROJECT=qwiklabs-gcp-03-ade964eda587

cp google_maps_mcp_agent/.env adk_mcp_server/.env

cd ~/gcp-adk-mcp-tools/adk_mcp_tools
adk web --allow_origins "regex:https://.*\.cloudshell\.dev"

A new browser tab opens with the ADK Dev UI. From the Select an agent drop-down on the left, select the google_maps_mcp_agent. Start a conversation with the agent and run the following prompts:

Get directions from GooglePlex to SFO.

👉 Task 3. Build an MCP server with ADK tools (MCP server exposing ADK)

python3 ~/gcp-adk-mcp-tools/adk_mcp_tools/adk_mcp_server/adk_server.py

In a new terminal window:

export PATH_TO_YOUR_MCP_SERVER_SCRIPT="/home/$USER/gcp-adk-mcp-tools/adk_mcp_tools/adk_mcp_server/adk_server.py"
echo $PATH_TO_YOUR_MCP_SERVER_SCRIPT
cd ~/gcp-adk-mcp-tools/adk_mcp_tools
adk web --allow_origins "regex:https://.*\.cloudshell\.dev"

To view the web interface in a new tab, click the http://127.0.0.1:8000 link in the terminal output.
From the Select an agent drop-down on the left, select the adk_mcp_server.
Prompt the agent with the following:
