MCP-agent Python workflows

lastmile-ai/mcp-agent is a Python framework for building MCP-connected agents with orchestrator-worker, router, evaluator-optimizer, map-reduce, durable execution, human input, token accounting, and OpenTelemetry patterns. Why it matters: MCP projects can become heavy quickly. A Python-first framework with normal control flow and observability hooks may be easier to evaluate than adopting a larger graph stack by default.

Try this: Review one example that combines MCP tools, token accounting, and durable execution; only adopt the framework if those features match a concrete agent use case.
