About

What is mcp-agent?

mcp-agent is an open-source framework designed for building effective AI agents using the Model Context Protocol (MCP). It provides a simple, composable approach, implementing patterns described in Anthropic's "Building Effective Agents" guide. The framework offers full MCP support, managing server connections and agent lifecycles automatically. It enables developers to connect LLMs to MCP servers using patterns like map-reduce, orchestrator, and router. A key differentiator is its durable execution capabilities, scaling to production workloads with Temporal as the backend, allowing agents to pause, resume, and recover without API changes. mcp-agent is Pythonic, using decorators and context managers for easy integration, and supports deployment to cloud environments.

Best used for

Ideal for developers who need to build robust and scalable AI agents, integrate various tools via Model Context Protocol, and ensure durable execution for production workloads. Especially valuable for creating agents that can perform complex tasks like file system interactions, web fetching, and multi-turn conversations.

FAQs

What is the Model Context Protocol (MCP) and how does mcp-agent utilize it?

The Model Context Protocol (MCP) is a standard for agents to interact with tools and resources. mcp-agent fully implements MCP, handling the lifecycle of MCP server connections. This allows agents to seamlessly integrate with various MCP servers like filesystem, fetch, or custom services, enabling them to use diverse tools without complex setup.

Does mcp-agent support durable execution for long-running agent workflows?

Yes, mcp-agent supports durable execution by integrating with Temporal as its agent runtime backend. This allows agents to pause, resume, and recover from failures without requiring any changes to the agent's API. This feature is crucial for building robust, production-ready agent applications that can handle sophisticated, long-running workflows.

What kind of LLMs can be integrated with mcp-agent?

mcp-agent can integrate with various LLM providers through its Augmented LLM feature. It supports providers like OpenAI, Anthropic, Google, Azure, and Bedrock. Developers can attach these LLMs to agents, enabling them to leverage the agent's tools, memory, and structured output helpers for tasks like generating text or structured data.
