From 6aa6a67d0e0404662574386419a857d38baf445c Mon Sep 17 00:00:00 2001 From: Bleyle Date: Tue, 9 Jun 2026 01:02:46 +0300 Subject: [PATCH 1/2] Release keeperhub-mcp Python 0.1.1 with py.typed, LICENSE, and retry cap. Rename distribution to keeperhub-mcp (mirrors @keeperhub/mcp). Add py.typed marker, bundle LICENSE in wheel/sdist, and cap session re-init retries to match the TypeScript client.
