- server.py: `mcp.server.mcpserver.MCPServer`; StrictArgsFastMCP becomes StrictArgsMCPServer, whose call_tool takes and forwards v2's `context` and raises ToolError (the SDK logs anything else as an unexpected crash; the message reaches the caller either way). - stateless_http and transport_security moved from the constructor to `streamable_http_app(...)` in mount_mcp, with their reasons. - Per-request user identity is unchanged: the contextvar set around the ASGI call reaches the handler on both v2 paths (legacy stateless spawns from the request task; the 2026-07-28 modern path opens its task group inside the request). - pyproject: mcp[cli]>=2.2, no ceiling (installs are --locked). uv.lock regenerated with --upgrade-package mcp in the ci-python image: only mcp and its own dependencies moved (106 → 110 packages).
