Fast Agent

• source
  • fork : (~/projects/wgong/MCP/fast-agent)
• story

A framework with complete, end-to-end tested MCP Feature support including Sampling, which helps create and interact with sophisticated Agents and Workflows in minutes. Both Anthropic (Haiku, Sonnet, Opus) and OpenAI models (gpt-4o/gpt-4.1 family, o1/o3 family) are supported

Demos

FastMCP

A fastmcp tutorial

• MCP server:
  • mcp_server.py: collection of tools/resources like calculator, trigonometry function, yahoo finance API call
• MCP clients:
  • mcp_client_simple.py: simple client with rule-based query parsing
  • mcp_client_llm.py: client with LLM-based query parsing
  • mcp_client_llm_resource.py: client with LLM parsing and calling tool/resource (see readme_tool_resource.md for details)

see readme_gemini.md for more details
