About

mcp-agent builds agents that connect to MCP servers for tools, resources and prompts, and it can expose agents themselves as MCP servers. It implements the composable patterns from Anthropic's Building Effective Agents guide, such as orchestrator, router and evaluator, and it can run durable workflows on Temporal that pause and resume. Observability uses OpenTelemetry, and the docs describe deploying MCP servers and agents to a managed cloud through a CLI.

Use cases: agent-orchestration, api-integration
