What changed

Remediates Dependabot #35 (GHSA-vj7q-gjh5-988w, high — "MCP Python SDK: WebSocket server transport does not support Host/Origin validation", fixed 1.28.1), a residual surfaced after #328. The semantic-kernel 1.44 bump left mcp resolving to 1.27.2 (still vulnerable). semantic-kernel only floors mcp>=1.26.0 (no cap), so this adds a direct mcp>=1.28.1 requirement to python/semantic-kernel-tool-policy/pyproject.toml, forcing the patched 1.28.1. The example runs no mcp WebSocket server (the vuln is server-transport-only, not reachable here) — pinned patched regardless.

…988w)

The semantic-kernel 1.44 bump (#328) left mcp resolving to 1.27.2, still
vulnerable to GHSA-vj7q-gjh5-988w (mcp WebSocket server Host/Origin
validation, fixed 1.28.1) — Dependabot #35. semantic-kernel only floors
mcp>=1.26.0, so add a direct mcp>=1.28.1 requirement to force the patched
version. The example runs no mcp WebSocket server (vuln not reachable) but
pin it patched regardless. uv sync --extra dev resolves; 6/6 tests pass.
