Tutorial: Building Custom MCP Servers With FastMCP and Integrating AI Agents Using...
summary
Builds a working pipeline: a FastMCP server running on localhost:801 hosting tool endpoints, a Google ADK-based country agent with four tools (get country info, weather, public holidays, current date) and a sub exchange agent with two tools (get exchange rate, current date), plus an A2A server agent on port 802 and an agent gateway routing ports 3000/3001 to enforce per-agent tool access. Live API calls return JSON, agents delegate currency queries to the exchange agent, and the demo works end-to-end. FastMCP Google ADK agent gateway
