A call center agent that can help with ordering a taxi. This demo repository uses Google ADK for now. Maybe CrewAI later.
# initialize project with deps and tools
uv init
uv add google-adk
uv tool install google-adk
# run and open the demo console
# choose the simple_taxi_agent
# the agent only supports voice
adk web
open http://localhost:8000goreleaser build --snapshot --clean
goreleaser release --skip=publish --snapshot --cleanIf you want to use the tool locally, e.g. with Claude Desktop, use the following configuration for the MCP server.
{
"mcpServers": {
"gcloud": {
"command": "/Users/mario-leander.reimer/Applications/gcp-mcp-server",
"args": ["--transport", "stdio"],
"env": {
}
}
}
}Alternatively, you can use the MCP introspector for easy local development:
# as stdio binary
npx @modelcontextprotocol/inspector go run main.go
# as SSE server using
go run main.go --transport sse
npx @modelcontextprotocol/inspector npx mcp-remote@next http://localhost:8001/sse
npx @modelcontextprotocol/inspector# make sure you enabled these Google APIs
gcloud services enable cloudbuild.googleapis.com artifactregistry.googleapis.com
gcloud services enable run.googleapis.com
# deploy the MCP server first
gcloud run deploy taxi-mcp-server --source=taxi-mcp-server/ \
--region=europe-north1 \
--port=8001 --allow-unauthenticated \
--set-env-vars=BASE_URL=https://taxi-mcp-server-343509396461.europe-north1.run.app
# now we deploy the agent with UI
export GOOGLE_API_KEY=<insert here>
# we use plain gcloud CLI to perform the deployment
gcloud run deploy simple-taxi-agent --source=. \
--region=europe-north1 \
--port=8000 --allow-unauthenticated \
--set-env-vars=MCP_SERVER_URL=https://taxi-mcp-server-343509396461.europe-north1.run.app/sse,GOOGLE_API_KEY=$GOOGLE_API_KEY,GOOGLE_GENAI_USE_VERTEXAI=FALSE
# there is a `adk deploy cloud_run command`
# however, it lacks the possibility to provide ENV variables
# also, the --with_ui option does not seem to have effect
# if you need to debug have a look at the logs
gcloud run services logs read taxi-mcp-server --region=europe-north1
gcloud run services logs read simple-taxi-agent --region=europe-north1
# use these commands to delete the workloads
gcloud run services list
gcloud run services delete taxi-mcp-server --async --region=europe-north1
gcloud run services delete simple-taxi-agent --async --region=europe-north1M.-Leander Reimer (@lreimer), [email protected]
