9d7afdf8e6Adds a workflow that drives this checkout's FastMCP through the latest releases of two major consumers, modeled on uv's ecosystem tests. pydantic-ai's MCPToolset is built on fastmcp.Client, so it runs in the project environment and connects in-process, over stdio, and over streamable HTTP. langchain-mcp-adapters pins mcp<2, so it cannot share an environment with FastMCP 4; it runs in its own environment and reaches the server over stdio and HTTP, covering handshake-era clients. Each path runs an agent loop with a scripted model, direct tool calls, structured output, tool errors, elicitation, progress, logging, resources, resource templates, and prompts.
