Build effective agents with Model Context Protocol using simple, composable patterns.

mcp-agent is a simple, composable framework to build agents using Model Context Protocol.

We believe that MCP is all you need to build agents. In practice, that means:

• Agents connect to the outside world via MCP. Tools, resources, and prompts are exposed via MCP servers, leading to simple agent design.
• Agents expose themselves over MCP. Agents themselves can be deployed as MCP servers, so any MCP client can invoke your agent, and agents can even invoke other agents over the same vendor-neutral protocol.

MCP-Cloud

mcp-c is the cloud platform for deploying mcp-agents and MCP servers. Without code changes, mcp-c lets you deploy mcp-agents as remote MCP servers (SSE/streaming HTTP) and execute tools as durable, long-running, fault-tolerant (Temporal) workflows.
