fast-agent is a Python CLI-first framework for building, running, and evaluating LLM agents with first-class MCP, ACP, and A2A protocol support. It provides an interactive terminal UI with shell integration, skills/plugins, workflow orchestration, and broad provider support including local llama.cpp models.

Use cases

  • build and evaluate llm agents from the terminal
  • coding agent with shell and subagent support
  • connect and test mcp servers with sampling and elicitation
  • expose an agent as an a2a or acp endpoint
  • run local llama.cpp models with an agent harness
  • evaluate model accuracy and cost across providers
  • manage agent skills and plugins

When to choose

  • you want a terminal-native, scriptable agent harness with strong MCP support
  • you need ACP/A2A client and server interoperability
  • you want broad provider coverage including local models and Codex subscriptions
  • you need agent evaluation and workflow tooling in Python

When to avoid

  • you need a hosted GUI or web-based agent builder
  • you only want a simple chatbot SDK without protocol integrations
  • you require a non-Python runtime
