# NOTE: 2.0.0 is a breaking upstream release: mcp.server.fastmcp is gone
# (replaced by mcp.server.mcpserver), the wire types moved into the
# mcp-types dist (exact ==${PV} pin upstream), and httpx was swapped for
# the pydantic fork httpx2. ::guru carries 1.28.1 for consumers that
# still need the 1.x API (e.g. dev-python/fastmcp).
