grafana/mcp-grafana v1.6.1

on GitHub

Fixed

• The stdio server no longer stops answering requests once a client opens a subscriptions/listen stream on protocol 2026-07-28, which made tools/list time out in clients such as Claude Code and GitHub Copilot CLI (#1236)
• Blank optional fields in the Claude Desktop extension (MCPB) no longer pass literal ${user_config.*} placeholders as credentials, so username/password auth works when the service account token field is left empty (#1249)
