)
print(result["messages"][-1].content)This connects to the remote AgentDeals server at https://agentdeals.dev/mcp — no npm or local install needed. The MultiServerMCPClient handles the MCP session lifecycle automatically.
You can also run AgentDeals locally via stdio transport:
"agentdeals": {
"command": "npx",
"args": ["-y", "agentdeals"],
"transport": "stdio",
}Use the agent to search for free databases, then compare the top options side by side.
result = await agent.ainvoke(
{"messages": [{"role": "user", "content":
"Search for free database hosting options, then compare "
"Supabase vs Neon vs PlanetScale. Show free tier limits "
"and risk levels."
}]}
)
print(result["messages"][-1].content)Monitor recent pricing changes for the vendors you use — catch free tier removals before they affect you.
result = await agent.ainvoke(
{"messages": [{"role": "user", "content":
"Track recent pricing changes for Vercel, Supabase, and "
"Cloudflare. Are any free tiers at risk?"
}]}
)
print(result["messages"][-1].content)Get stack recommendations with cost projections at different scale points.
result = await agent.ainvoke(
{"messages": [{"role": "user", "content":
"Plan a free stack for a SaaS MVP: I need hosting, "
"database, auth, email, and monitoring. Estimate costs "
"at 1K, 10K, and 100K monthly active users."
}]}
