Bumps mcp from 1.26.0 to 1.28.1.

Release notes

Sourced from mcp's releases.

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.
