Representing Agents as MCP Servers

In plain words

mcp-agent is a lightweight framework that enables AI agents to function as Model Context Protocol (MCP) servers. This allows any MCP client to invoke and orchestrate agents alongside other tools and resources using a unified protocol. The framework implements standard agent patterns and handles MCP server and client management. It is designed for developers building multi-agent systems and applications that need to integrate agentic behavior with existing MCP-compatible tools.

Build effective agents using Model Context Protocol and simple workflow patterns - mcp-agent/examples/mcp_agent_server at main · lastmile-ai/mcp-agent

This directory contains examples of exposing MCP Agent workflows as MCP servers. It demonstrates how to build, launch, and interact with agent-powered MCP servers in different execution environments. The MCP Agent Server pattern represents a significant evolution in agent architecture. While traditional MCP clients (like Claude, Cursor, VS Code) often act as agents consuming MCP server tools, these examples flip the paradigm: Each implementation directory contains its own README with detailed instructions. Prefer the decorator-based tool definition ( @app.tool / @app.async_tool ) for the simplest developer experience: from mcp_agent . app import MCPApp app = MCPApp ( name =…from github.com

In the maker’s words, at launch

Hey HN! A few months ago we shared mcp-agent (https://github.com/lastmile-ai/mcp-agent) [1][2], a lightweight framework that implements every agent pattern from Anthropic’s Building Effective Agents blog [3] and handles MCP server/client management seamlessly. Our core bet is that connecting…

  Mcp-Agent – Build effective agents with Model Context Protocol2025 · github.com · ▲80

  Hey HN, I spent my xmas break building an agent framework called mcp-agent [1](https://github.com/lastmile-ai/mcp-agent) for Model Context Protocol [2]. It makes it easy to build AI apps with MCP servers, and implements every pattern from the popular Building Effective Agents blog [3] as well as OpenAI’s Swarm [4]. I’m sharing it early to get community feedback on where to take it from here, and to ask for contributions. For those who aren’t familiar with MCP, I think of it as a standardized interface to let AI communicate with software via tool calls, resources and…

  Fast-agent – Compose MCP enabled Agents and Workflows in minutes2025 · github.com · ▲29

  Hello, HN. I've created fast-agent to make building my own products easier - and remove the friction between defining Prompts, MCP Servers and their composition. It uses a simple, declarative style that's easy to work with and source control - with inbuilt support for the patterns in the Building Effective Agents paper. Because you can "warm-up" and interact with Agents before, during or after the workflows, it's easy to diagnose and tune Agent prompts and behaviour for later runs. Being able to set these workflows up makes LLM Context Management and Tool Selection a lot easier and can…

  Tapflow 2.0▲1,125

  We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship. Fully bootstrapped and just launched on PH today →…
