[`mcp-agent`](https://github.com/lastmile-ai/mcp-agent) is a simple, composable framework to build effective agents using [Model Context Protocol](https://modelcontextprotocol.io/introduction).

**mcp-agent**'s vision is that MCP is all you need to build agents, and that simple patterns are more robust than complex architectures for shipping high-quality agents.
When you're ready to deploy, [`mcp-c`](https://docs.mcp-agent.com/get-started/cloud) let's you deploy any kind of MCP server to a managed Cloud. You can even deploy agents as MCP servers!

            name="researcher",
            instruction="Use available tools to gather concise answers.",
            server_names=["fetch", "filesystem"],
        )

        async with agent:
            llm = await agent.attach_llm(OpenAIAugmentedLLM)
            report = await llm.generate_str("Summarize the latest MCP news")
            print(report)
