Bumps mcp from 1.27.0 to 1.28.1.

Release notes

Sourced from mcp's releases.

v1.28.1

What's Changed

Full Changelog: modelcontextprotocol/python-sdk@v1.28.0...v1.28.1

v1.28.0

Deprecations

Two API surfaces now emit DeprecationWarning ahead of their removal in v2. Nothing is removed in 1.x, and the warnings fire only when the deprecated API is called - importing the modules stays silent.

  • WebSocket transport - mcp.client.websocket.websocket_client and mcp.server.websocket.websocket_servermodelcontextprotocol/typescript-sdk#1783
  • Experimental tasks API - ClientSession.experimental, Server.experimental, ServerSession.experimental, and the experimental_task_handlers= kwarg on ClientSession. Tasks (SEP-1686) were removed from the MCP specification and are expected to return as a separate MCP extension.

If your test suite runs with filterwarnings = ["error"] and exercises these paths, add a scoped ignore such as ignore:The experimental tasks API is deprecated:DeprecationWarning or ignore:The WebSocket .* transport is deprecated:DeprecationWarning.

See #2828 for full details.
