Marcelo Trylesinski b42d5cd5fe Extract protocol types into a standalone mcp-types package

Convert the repository into a uv workspace mirroring pydantic/httpx2. The
root pyproject becomes a pure coordinator (package = false) and the two
distributable packages live nested under src/<pkg>/<pkg>/ each with their
own pyproject:

- src/mcp/mcp/ -> mcp
- src/mcp-types/mcp_types/ -> mcp-types (import mcp_types)

The protocol types (_types.py, jsonrpc.py) move into mcp_types, which only
depends on pydantic and typing-extensions. mcp depends on mcp-types via
uv-dynamic-versioning, so installing mcp still pulls the types in. The
mcp.types module path is removed; all imports now use mcp_types. The
curated re-exports on the top-level mcp package are unchanged.

Simple Task Server

A minimal MCP server demonstrating the experimental tasks feature over streamable HTTP.

Running

cd examples/servers/simple-task
uv run mcp-simple-task

The server starts on http://localhost:8000/mcp by default. Use --port to change.

What it does

This server exposes a single tool long_running_task that:

Must be called as a task (with task metadata in the request)
Takes ~3 seconds to complete
Sends status updates during execution
Returns a result when complete

Usage with the client

In one terminal, start the server:

cd examples/servers/simple-task
uv run mcp-simple-task

In another terminal, run the client:

cd examples/clients/simple-task-client
uv run mcp-simple-task-client
