Bumps mcp from 1.27.1 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.

Resolved by #343, merged at f4234f9e481dd9c54e10048a2d67f7216a75f9e1, for Agentic 26.10.1.

Lock MCP 2.3.0 and FastMCP 4.1.0, satisfying the patched-version intent and the current consumer protocol contract.

The combined change preserves compatible provider extras and is qualified as one dependency graph. The resolution record records all requests and the six remaining optional-package advisories. This closes the superseded proposal while retaining its full history.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
